Abstract
OBJECTIVES: The purpose of this study was to evaluate the efficiency of bleaching
after combining ozone and 38% H2O2 in comparison to the sole use of 38% H2O2.
METHODS: Consecutive 26 participants (13 males and 13 females) were recruited into
this study. They were randomly allocated into 2 groups (n=13 for each group). In group
1 (test group); the participants' upper anterior teeth were treated with 38% H2O2 for
20min then the teeth were exposed to ozone for 60s (healOzone(®) X4, KaVo Dental,
Biberach, Germany). In group 2 (controls); the upper anterior teeth were treated with
20min of 38% H2O2 only. The shade of teeth was evaluated by recording the L* a* b*
values and Vita Classic shades at study baseline and after bleaching in both groups. The
statistically significant changes were set at P≤0.05.
RESULTS: Tooth sensitivity and teeth shades were comparable between groups at study
baseline (p>0.05). Controls reported more tooth sensitivity following bleaching
(p<0.001). Teeth achieved better Vita shades, higher L* values (lighter shades), and
lower a* and b* values (lighter shades) after bleaching in both groups (P≤0.05).
However, teeth bleached with H2O2 and ozone achieved better Vita shades, higher L*
values and lower a* values (lighter shades) than those bleached with H2O2 alone
(p<0.001). Changes in b* values were not significantly different between groups.
CONCLUSIONS: Bleaching with 38% H2O2 for 20min followed by 60s of ozone
application would result in teeth with lighter shades than bleaching with 38% H2O2
alone. KEYWORDS: Bleaching; H(2)O(2); HealOzone; Ozone; Tooth shade. Copyright

Abstract
This study aimed to evaluate the use of ozone to treat recurrent aphthous stomatitis
(RAS). Consecutive sixty-nine participants with RAS were recruited into this nonrandomized double blind, controlled cohort observational study (test group). A control
group of 69 RAS patients who matched test group with age and gender was recruited.
RAS lesions in test group were exposed to ozone in air for 60 seconds while controls
received only air. Ulcer size and pain were recorded for each participant at baseline and
daily for 15 days. Ulcer duration was determined by recording the time taken for ulcers to
disappear. The main outcome measures were pain due to the ulcer, ulcer size and ulcer
duration. 138 RAS participants (69 participants and 69 controls) were analyzed. Ulcer
1
size was reduced starting from the second day in test group and from the fourth day in
controls (p ≤ 0.004). Pain levels were reduced starting from the first day in the test group
and from the third day in controls (p ≤ 0.001). Ulcer duration, ulcer size after day 2 and
pain levels were more reduced in the test group. In conclusion, application of ozone on
RAS lesions for 60 seconds reduced pain levels and enhanced ulcers' healing by reducing
ulcers' size and duration.

Improved tooth bleaching combining ozone and hydrogen peroxide--A blinded
study.
Al-Omiri MK1, Abul Hassan RS2, AlZarea BK3, Lynch E4.
Author information
Abstract
OBJECTIVES: To evaluate the efficacy of tooth bleaching using ozone after hydrogen
peroxide (H2O2) in comparison to the use of H2O2 alone.
METHODS: 70 extracted teeth were randomly distributed into two groups. Teeth
surfaces in group 1 (n=35) were treated using 38% H2O2 and then were exposed to
ozone for 60s and this ozonated peroxide mixture was left on the teeth for 20 min.
Meanwhile, teeth in group 2 (n=35) were treated with H2O2 38% for 20 min. The L* a*
b* and Vita Classic shade values of teeth were evaluated in both groups at base line,
after application of H2O2 and ozone in group 1, and after application of H2O2 and then
again after another application of ozone in group 2. The statistically significant changes
were set at P ≤ 0.05.
RESULTS: Baseline L* a* b* and Vita shade values were comparable between groups
(P>0.05). Teeth obtained lighter shades following bleaching with both H2O2 and ozone
or with H2O2 alone (P ≤ 0.05). Further bleaching with ozone for teeth already bleached
with H2O2 alone showed further improvement of the shades of teeth (P<0.001). Teeth
treated with H2O2 and ozone had more shade improvements than those only treated with
H2O2 (P<0.001). Also, L* values were increased while b* values were decreased (teeth
obtained lighter shades) following bleaching in both groups (P ≤ 0.05). More changes
were obtained when both ozone and H2O2 were used (P ≤ 0.05).
CONCLUSIONS: Bleaching with 38% H2O2 and ozone resulted in teeth with lighter
shades than bleaching with 38% H2O2 alone. KEYWORDS: Bleaching; HealOzone;

Abstract
2
OBJECTIVE: The aim of the current investigation was to study the prevalence of
temporomandibular disorder (TMD) among university students of North Saudi Arabia.
METHODS: A specifically constructed questionnaire was distributed to 489 university
students to investigate the prevalence of temporomandibular joint (TMJ) findings among
them. The study sample consisted of 346 males and 143 females (age range was 1825 years). The data were analyzed, and probability values were set at P ≤ 0.05.
RESULTS: A total of 49.7% of participants had at least one sign or symptom of TMD.
Clicking was the most reported finding. Pain in or about the ears/cheeks was the second
most common finding. In all, 24.3% of the participants reported one TMJ finding;
meanwhile, 0.4% reported the presence of five concurrent TMJ signs and symptoms.
Females reported more TMJ signs and symptoms than males (P < 0.05). Science and
health students reported more TMD findings than humanitarian college students
(P < 0.05).
DISCUSSION: University students in north Saudi Arabia reported high prevalence of
TMD. Also, students from science and health colleges reported higher prevalence of
TMD findings than humanitarian college students. Clicking and pain are the most
prevalent findings of TMD among university students. The results of this investigation
highlight the need for additional research to shed more light on the risk factors and
findings related to TMD. This will facilitate drawing adequate guidelines for prevention
and management of TMD.

Relationship between impact of maxillary anterior fixed prosthodontic
rehabilitation on daily living, satisfaction, and personality profiles.
Sghaireen MG1, Al-Omiri MK2.
Author information
Abstract
STATEMENT OF PROBLEM: Personality profiles may affect the impact of dental
treatment on daily living and patient satisfaction.
PURPOSE: The purpose of this clinical trial was to evaluate the impact of maxillary
anterior fixed prosthodontic rehabilitation on daily living and the satisfaction of patients
and to investigate its relationship with personality profiles.
MATERIAL AND METHODS: Fifty-nine participants (25 men and 34 women; mean
age 32.4 ± 6.9 years) received maxillary anterior partial fixed dental prostheses. The
clinical success of the prostheses was evaluated following specific criteria. The Dental
Impact on Daily Living (DIDL) questionnaire was used to measure satisfaction with the
prostheses and their impact on daily living. The Neuroticism-Extraversion-Openness
Five-Factor Inventory (NEO-FFI) was used to measure patients' personality profiles. The
paired sample t test was used to compare satisfaction and personality scores before and
after treatment (α=.05).
RESULTS: Participants' total satisfaction and their satisfaction with appearance, pain
tolerance, oral comfort, general performance, and eating improved after treatment
(P<.05). Before treatment, women were less satisfied with general performance (P=.047)
3
and scored higher on the Neuroticism score (P=.039); however, after treatment, women
were more satisfied with appearance (P=.004). Age and sex had no significant
correlation with personality profiles after treatment. Before treatment, Neuroticism,
Openness, and Conscientiousness scores were associated with dental satisfaction and
impact on daily life (P<.05). After treatment, Neuroticism, Openness, and Extraversion
scores were associated with dental satisfaction and impact on daily life (P<.05).
CONCLUSIONS: Patient satisfaction with their oral condition improved after partial
fixed dental prosthetic rehabilitation in the maxillary anterior esthetic zone.
Psychological profiles (Neuroticism, Extraversion, Openness, and Conscientiousness)
may be involved in and explain the impact on daily living and the degree of patient
satisfaction with their prostheses.

Antifungal prescribing pattern and attitude towards the treatment of oral
candidiasis among dentists in Jordan.
Al-Shayyab MH1, Abu-Hammad OA2, Al-Omiri MK3, Dar-Odeh NS4.
Author information
Abstract
AIM: The aim of this study was to evaluate the attitude of Jordanian dentists towards the
treatment of oral candidiasis and their current antifungal prescribing habits, shedding
more light on the possible influence of their socio-professional factors on the pattern of
prescribing and practice.
METHODS: A structured validated questionnaire was developed and tested; it was then
emailed to a random sample of 600 Jordanian dental practitioners during the period of
this cross-sectional survey. The questionnaire recorded practitioners' personal details and
their attitude and prescribing of antifungal therapy for oral candidiasis. Statistical
significance was based on probability values of <0.05 and was measured using the chisquare and Fisher's exact tests. Multiple logistic regression analysis was used to analyse
the influence of respondents' socio-professional factors on their attitude towards oral
candidiasis.
RESULTS: Of the 423 questionnaires returned, only 330 were included. The attitude of
respondents was significantly influenced by their experience [odds ratio (OR) = 0.14; P
< 0.001] and workplace (OR = 4.70; P < 0.001). Nystatin was the most commonly
prescribed antifungal agent (78.2%), followed by miconazole (62.4%), which was
prescribed for topical use. Systemic antifungals were prescribed by 21.2% of
respondents, with a significant (P < 0.05) association with the country in which their
qualification was obtained.
CONCLUSION: The attitude towards the treatment of oral candidiasis is much better
among the least-experienced dentists working in private practice. Nystatin and
miconazole are the most popular choices of antifungal agents among Jordanian dentists.

perception and experience before and after orthodontic treatment.
Abu Alhaija ES1, Abu Nabaa MA, Al Maaitah EF, Al-Omiri MK.
Author information
Abstract
OBJECTIVE: To compare personality traits, attitude toward orthodontic treatment, and
pain perception and experience before and after orthodontic treatment.
MATERIALS AND METHODS: One hundred subjects (50 male and 50 female) were
included in this study. The mean (SD) age was 17.5 (2.05) years at T1 and 19.15 (2.32)
years at T2. The instruments for data collection were questionnaires that included
assessment of patients' personality traits, attitudes toward orthodontic treatment, and pain
perception/experience. Subjects completed the questionnaires at two different times:
before orthodontic treatment (T1) and after fixed orthodontic treatment (T2). Subjects
5
were treated by fixed orthodontic appliances for an average (SD) period of 18.64 (0.35)
months. Paired sample t-test and chi-square test were used to detect any differences.
RESULTS: Significant changes in personality traits were detected after orthodontic
treatment irrespective of gender. Neuroticism, openness, agreeableness, and
conscientiousness scores were improved (P < .001). A positive attitude toward
orthodontic treatment was reported at T1 (4.31 [±1.26]) and improved at T2 (3.98
[±1.16]) irrespective of gender (P < .05). The average (SD) expected pain score (T1) was
4.73 (1.88) and the average (SD) experienced pain score (T2) was 4.63 (1.58).
Significant difference in the expected and experienced pain scores was not detected (P = .11). CONCLUSIONS: Personality traits and attitude toward orthodontic treatment
improved after orthodontic treatment. Reported actual pain experience during
orthodontic treatment was similar to that expected before treatment. KEYWORDS:

Abstract
OBJECTIVES: This study aimed to clinically quantify the apicoincisal height of the
upper interproximal areas directly in patients' mouths compared to measurements on
stone models.
SUBJECTS AND METHODS: One hundred and fifty participants (75 females and 75
males, age range 20-45 years) were recruited for this study. A digital caliper was used to
measure the anterior maxillary interproximal contact areas directly in patients' mouths
and on stone models. The digital caliper accuracy was up to 0.01. The Statistical Package
for Social Sciences software (SPSS, version 19.0, Chicago, Ill., USA) was used for
statistical analysis. Statistical significance was based on probability values <0.05.
RESULTS: The intraoral measurement of proximal contacts as well as the measurement
on stone models showed that the dimensions of interproximal contacts on both sides of
each tooth were significantly different (p < 0.001) and that the dimension of the mesial
contact point was larger than that of the distal contact point of each tooth. The largest
contact point was the one between the central incisors (direct intraoral measurement =
2.9-6.49 mm; model measurement = 3.31-6.91 mm). On the other hand, the contact point
between the canine and first premolar was the smallest on both sides of the arch (0.632.52 mm intraorally, 0.98-2.88 mm on models). The intraoral measurement of contact
points was more accurate than model measurements, and the differences were
statistically significant (p < 0.001).
CONCLUSIONS: The clinical evaluation of contact point dimensions using a digital
caliper was more precise than measuring contact points on stone models; hence, it is a
viable, quick and adequate method to be used routinely.

Abstract
INTRODUCTION: The aim of this study was to investigate whether there is a
relationship between self-reported bullying because of dentofacial features and oral
health-related quality of life among a representative sample of Jordanian schoolchildren.
METHODS: This was a cross-sectional study in which a representative sample of sixthgrade students (age, 11-12 years) from randomly selected schools in Amman, Jordan,
were asked to complete questionnaires distributed in the classroom in the presence of the
researchers. The questionnaire used for this purpose was the short form of the Child
Perceptions Questionnaire for 11- to 14-year-old children. The final sample size was 920
children (470 girls, 450 boys).
RESULTS: There were significant differences between the sexes for the total Child
Perceptions Questionnaire score and for the oral symptoms and the social well-being
subscales, with boys reporting higher scores and thus more negative effects on their oral
health-related quality of life. Comparison of the total scores and subscales scores for
boys and girls subdivided into those who reported being bullied and not being bullied
about their teeth showed that bullied boys had significantly greater effects on overall oral
health-related quality of life and on all subscales than did not-bullied boys (P <0.001 for
all comparisons). Bullied girls also had significantly greater effects on the overall oral
health-related quality of life and all subscales than did not-bullied girls (P <0.001 for all
comparisons). However, bullied boys and girls reported similar scores for the different
subscales of the Child Perceptions Questionnaire; there were no significant differences.
CONCLUSIONS: This study demonstrated a significant relationship between bullying
because of dentofacial features and negative effects on oral health-related quality of life.
The results highlight the importance of addressing the bullying problem among
schoolchildren and provide important data for educational authorities to create
antibullying programs to help students receive education in a safe and healthy
environment. Copyright © 2014 American Association of Orthodontists. Published by

Recurrent aphthous stomatitis (RAS): a preliminary within-subject study of quality
of life, oral health impacts and personality profiles.
Al-Omiri MK1, Karasneh J, Alhijawi MM, Zwiri AM, Scully C, Lynch E.
Author information
Abstract
BACKGROUND: RAS may affect quality of life and impacts oral health and daily
activities; consequently, psychological factors, dental needs and patients' perceptions.
Professionals should understand this relation to adequately manage oral ulcers. This
study aimed at investigating the relationship between oral health impacts, oral health7
related quality of life and psychological profiles in patients with recurrent aphthous
stomatitis (RAS).
METHODS:Fifty-three patients (30 men and 23 women, mean age: 31.1 ± 10.1 years)
with RAS participated in this study. During ulcer episodes, participants completed
Hospital Anxiety and Depression Scale (HAD), Neuroticism-Extraversion-Openness
Five Factor Inventory (NEO-FFI), Oral Health Impact Profile (OHIP-14) and United
Kingdom Oral Health-Related Quality of Life measure (OHQoL-UK) proformas.
Patients completed OHIP-14 and OHQoL-UK again when they were ulcer-free. The
statistically significance levels were set at P ≤ 0.05.
RESULTS:During ulcer episodes, patients reported worse oral health impacts and an
inferior quality of life in comparison with ulcer-free times (P < 0.0001). Higher OHIP
scores were significantly associated with higher HAD depression (P = 0.036) and anxiety
(P = 0.012) scores. NEO-FFI scores had no significant relations with OHIP and OHQoLUK scores (P > 0.05). During ulcer-free periods, no relationships were detected between
OHIP, OHQoL-UK, HAD and NEO-FFI scores (P > 0.05), except between OHQoL-UK
and conscientiousness scores (P = 0.05).
CONCLUSIONS:RAS increased the negative oral health impacts on patients and
consequently lowered their quality of life. Stressful situations and conditions (including
anxiety and depression), rather than inherent personality profiles and stable
psychological traits, were related to oral health impacts and quality of life in patients
with RAS. KEYWORDS: HAD scale; NEO-FFI; OHIP-14; OHQoL-UK; recurrent

Abstract
The objective of this study was to collect information regarding methods, materials, and
attitudes employed during the endodontic treatment by dentists in north of Saudi Arabia.
A questionnaire was designed and distributed among 300 dentists in north of Saudi
Arabia to collect the data about the standard protocols of endodontic treatment. The
collected data was analyzed by using the SPSS 10 computer software. Out of a total of
300 surveyed dentists, the 66% response rate showed that this study was true
representation of the endodontic treatment performed by the dentists in north of Saudi
Arabia. 152 (76%) were general dentists and 48 (24%) were endodontists. 18 (9%) were
using rubber dam as the method of isolation during endodontic treatment. 173 (86.5%)
were using only measurement radiographs for working length determination and 27
(13.5%) were using both electronic apex locator and measurement radiographs. 95
(47.5%) of the respondents were using standardized technique and 25 (12.5%) were using
8
step-down as a root canal preparation technique. 127 (63.5%) of the respondents were
using lateral condensation technique, with gutta percha points for root canal obturation.

Maximum bite force following unilateral implant-supported prosthetic treatment:
within-subject comparison to opposite dentate side.
Al-Omiri MK1, Sghaireen MG, Alhijawi MM, Alzoubi IA, Lynch CD, Lynch E.
Author information
Abstract
Bite force is a significant component of chewing and masticatory function. The literature
lacks studies that compare bite force values of implant-supported fixed bridges to natural
dentition within same subjects. The objective of the study was to assess maximum
occlusal bite force (MBF) among patients with an implant-supported fixed prosthesis and
compare it to their opposite dentate side and also to determine the effect of gender, age
and Body Mass Index (BMI) on maximum occlusal bite force. Forty patients (20 males
and 20 females, mean age = 42.7 ± 9.6 years) with an implant-supported fixed prosthetic
rehabilitation on one side and dentate on the other side were recruited into this study.
Participants' MBF were measured bilaterally at the first molar region using a digital
hydraulic occlusal force gauge (GM10). The measurements were repeated three times
(with 45 s intervals between times) for each side, and the highest value of the bite force
(MBF) was recorded for each side. The mean MBF was 577.9 N at the implant-supported
prosthesis side and 595.1 N at the dentate side. The average MBF was higher at the
dentulous side (P < 0.05). Maximum occlusal bite force was higher in males and
participants with higher weight and height. However, BMI was not significantly related
to MBF values. Maximum occlusal bite force values at the dentate side were slightly
(3%) but significantly higher than MBF at implant-supported prosthesis side. Males,
taller patients and patients with higher weights had higher MBF values. Body mass index
was not significantly related to MBF values. KEYWORDS: bite force; bite force

Abstract
OBJECTIVES: To clinically quantify the apicoincisal height of interproximal areas
directly in patients' mouths.
METHODOLOGY: Thirty participants (11 females and 9 males, mean age=26±1.5
years) were recruited into this study. Measurement of interproximal contact areas was
carried out directly in patients' mouths using digital caliper (TERENSA, USA) with
measuring accuracy of 0.01 mm. The interproximal contact areas that were measured
are: central incisor to central incisor, central incisor to lateral incisor, lateral incisor to
canine, and canine to first premolar on both sides of the jaw. Statistical significance was
based on probability values less than 0.05 (p<0.05).
RESULTS: The largest contact point was the one present between central incisors and it
ranged from 2.9 to 6.5 mm. On the other hand, the contact point between canine and first
premolar was the smallest on both sides of the arch and ranged from 0.6 to 2.5 mm. The
dimensions of the contact points declined as we move from anterior area backwards.
Statistical analysis using t-test showed that there were significant differences between
the measurements of interproximal points of each tooth (P<0.05).
CONCLUSIONS: the apicogingival dimension of the contact point decreased as we
moved from anterior to posterior teeth. The contact area between the central incisors was
largest and the one between canine and premolar was the smallest. This study is the first
to report direct intra-oral clinical measurement of contact points. Clinical evaluation of
contact point dimensions using digital caliber is a viable, quick and accurate method to
use. KEYWORDS: Contact point; Interproximal contact; anterior teeth; dental

living, satisfaction and personality profiles.
Al-Omiri MK1, Sghaireen MG2, Al-Qudah AA3, Hammad OA4, Lynch CD5, Lynch E6.
Author information
Abstract
OBJECTIVES: To investigate dental impacts on daily living and satisfaction with
removable complete and partial prosthodontic rehabilitations, and to identify their
relationship with personality profiles.
METHODS: Sixty-eight patients (38 males and 30 females; mean age=53.2±11.8 years)
received removable prostheses (32 complete dentures and 36 removable partial
dentures). Clinical success of prostheses was assessed according specific criteria. The
Dental Impact on Daily Living (DIDL) questionnaire was utilized to assess satisfaction
with prostheses and impacts on daily living. NEO Five Factor Inventory (NEO-FFI) was
utilized to assess patients' personality profiles.
RESULTS: Participants' total satisfaction and satisfaction with appearance, pain
tolerance, oral comfort, and eating improved after treatment (p<.05). Position of
prosthesis and age had no significant relationships with satisfaction or personality scores
(p>.05). Females were less satisfied with appearance (p<.05). Patients who received
partial dentures were more satisfied with eating and scored higher total satisfaction
scores than those who had complete dentures (p<.05). Before treatment; Neuroticism and
Openness scores were associated with dental satisfaction and impacts (p<.05). After
10
treatment, Conscientiousness and Extraversion scores were associated with dental
satisfaction and impacts (p<.05).
CONCLUSIONS: Patients satisfaction with oral condition improved following using
removable prosthetic rehabilitation with RPD having better impacts than CD.
Psychological profiles (e.g. Neuroticism, Extraversion, Openness and
Conscientiousness) might play a role and explain prosthetic impacts on daily living and
patients' satisfaction with prostheses. KEYWORDS: DIDL; Impacts on daily living;

Abstract
The objective was to determine the expression and fluctuating asymmetry of two dental
morphological traits in the living Jordanians: The lingual cusp number on the lower
premolars (LP1 and LP2) and the hypoconulid (distal cusp) reduction on the lower first
molar (LM1). In addition, both intra- trait and inter- trait interactions were analyzed.
Three hundred school children (15.5 +/- 0.4 years) were involved. Impressions for the
mandibular dental arches were taken, and dental casts were reproduced. The abovementioned traits were observed. Paired sample t test and nonparametric correlation
analysis were used for data analysis. Three-cusped LP1 was found in 11.40 % of the
examined students, while the two-cusped LP1 was found in 88.60%. In comparison, the
Three-cusped LP2 was found in 61.40% while the two-cusped LP2 was found in 38.60%
of the observed subjects. The frequencies of the 4-cusped and 5-cusped LM1 were found
to be 8.65% and 91.35%, respectively. Nonparametric correlation analysis revealed
positive and statistically significant association between the expression of two lingual
cusps on LP1 and on LP2 in both genders (p < 0.01), while there was no significant
correlation between expression of two lingual cusps on either LP1 or LP2 and the
hypoconulid loss on LM1 in both genders (p > 0.05). Bilateralism was highly significant
in the tested traits in both genders (p < 0.001). This finding might be a sign of relatively
low environmental stresses experienced by the living Jordanians and/or great ability of its
individuals to buffer the adverse effects of such stresses on dental development. This
study is a useful addition to the existing literature in that it examines a previously poorly
11
characterized population and assists in placing the contemporary Jordanian population
within the current framework of human population groups globally.

Flare-up rate in molars with periapical radiolucency in one-visit vs two-visit
endodontic treatment.
Akbar I1, Iqbal A, Al-Omiri MK.
Author information
Abstract
PURPOSE: The objective of this study was to compare postobturation flare-ups
following single and two-visit endodontic treatment of molar teeth with periapical
radiolucency.
MATERIALS AND METHODS: A total of 100 patients with asymptomatic molar
teeth with periapical radiolucency were selected. They were randomly allocated into two
groups. Fifty patients received complete endodontic treatment in one-visit. Fifty patients
received treatment by debridement and instrumentation at the first visit followed by
obturation at the second visit.
RESULTS: 10% of patients had flare-ups in the single visit group and 8% of patients
had flare-ups in the two-visit group. Number of visits did not affect the success of
endodontic treatment (p>0.05). Age, gender and tooth type had no effects on the
occurrence of flare-ups regardless the number of visits (p>0.05).
CONCLUSION: One-visit endodontic treatment was as successful as two-visit
endodontic treatment as evaluated by rate of flareups in asymptomatic molar teeth with
periapical radiolucency.

Quantification of incisal tooth wear in upper anterior teeth: conventional vs new
method using toolmakers microscope and a three-dimensional measuring technique.
Al-Omiri MK1, Sghaireen MG, Alzarea BK, Lynch E.
Author information
Abstract
OBJECTIVES: This study aimed to quantify tooth wear in upper anterior teeth using a
new CAD-CAM Laser scanning machine, tool maker microscope and conventional tooth
wear index.
METHODS: Fifty participants (25 males and 25 females, mean age = 25 ± 4 years)
were assessed for incisal tooth wear of upper anterior teeth using Smith and Knight
clinical tooth wear index (TWI) on two occasions, the study baseline and 1 year later.
Stone dies for each tooth were prepared and scanned using the CAD-CAM Laser Cercon
System. Scanned images were printed and examined under a toolmaker microscope to
quantify tooth wear and then the dies were directly assessed under the microscope to
measure tooth wear. The Wilcoxon Signed Ranks Test was used to analyze the data.
RESULTS: TWI scores for incisal edges were 0-3 and were similar at both occasions.
Score 4 was not detected. Wear values measured by directly assessing the dies under the
12
toolmaker microscope (range = 113 - 150 μm, mean = 130 ± 20 μm) were significantly
more than those measured from Cercon Digital Machine images (range=52-80 μm, mean
= 68 ± 23 μm) and both showed significant differences between the two occasions.
CONCLUSIONS: Wear progression in upper anterior teeth was effectively detected by
directly measuring the dies or the images of dies under toolmaker microscope.
Measuring the dies of worn dentition directly under tool maker microscope enabled
detection of wear progression more accurately than measuring die images obtained with
Cercon Digital Machine. Conventional method was the least sensitive for tooth wear
quantification and was unable to identify wear progression in most cases.

An in vivo study to determine the effects of early preflaring on the working length in
curved mesial canals of mandibular molars.
Iqbal A1, Akbar I, AL-Omiri MK.
Author information
Abstract
AIM: To evaluate the effects of a preflaring method on the determination of working
length in the curved mesial canals of mandibular molars.
MATERIALS AND METHODS: Ninety mandibular molars with apical curvature of
30 to 40° were selected and randomly divided into two groups; each containing 45 teeth.
In the first group, the initial instrumentation was performed with preflaring on the
mesiobuccal canal (preflared group), and in the second group; the instrumentation was
performed without preflaring on the mesiobuccal canal (nonpreflared group). A size 15
K-file was inserted in the mesiobuccal canals until the apical constriction could be felt
by tactile sensation and a radiograph was taken to identify the distance between the file
tip and radiographic apex. The location of the tip was classified as (a) within 1 mm of
the radiographic apex, (b) more than 1 mm of the radiographic apex, or (c) overextended
beyond the radiographic apex. The collected data was statistically analyzed and
probability value was set to be ≤0.05.
RESULTS: The file tip was significantly closer to the true working length in the canals
with early preflaring compared to the canals without early preflaring (p < 0.005). In the
preflared group; 75.5% of the cases had the file tip in location 'a', 13.3% in location 'b',
and 11.1% in location 'c'. In the nonpreflared group; 33.3% of the cases had the file tip in
location 'a', 53.3% in location 'b' and 13.3% in location 'c'.
CONCLUSION: Preflaring the coronal portion of curved canals greatly improved the
access to the apical constriction, and thus enhanced correct working length
determination. If the coronal portion of the curved canals is not preflared, the clinician
cannot discern the accuracy of what they feel apically. Thus, preflaring is a highly
recommended procedure especially in curved canals for better determination of correct
working length.

Abstract
Aim of Study. To investigate dental anxiety levels among university students and its
relation with their specialty and gender. Materials and Methods. 850 undergraduate
university students were recruited into the study. The Modified Corah Dental Anxiety
Scale (MDAS) was used to measure the levels of their dental anxiety. 700 questionnaires
were returned, 390 females and 310 males (response rate of 0.92% among females,
0.73% among males). The MDAS score ranged from 5 to 25. Patients were considered to
suffer from high dental anxiety if they scored 13 to 20 points. Statistical analysis
significance was set at P ≤ 0.05. Results. Seven hundred students participated in this
study including 13% of medical students, 10% of dental students, 58% of arts students,
and 18% of computer science students. Medical and dental students were less anxious
than arts and computer science students (P < 0.05). Local anesthesia injection was the
most fearful dental procedure (P < 0.05). Females were more anxious than males (P <
0.05). Conclusion. Male students were less anxious than female students. Students from
medical background faculties were less anxious than students from nonmedical faculties.
Lack of adequate dental health education may result in a higher level of dental anxiety
among nonmedical students in Saudi Arabia.

Abstract
INTRODUCTION: The aim of this study was to investigate the relationship between
dental impacts on patients' daily living, satisfaction with the dentition and personality
profiles.
MATERIALS AND METHODS: Fifty-two patients (22 males and 30 females; mean
age 22.7 +/- 5.5 years) were recruited for this study. A "dental impact on daily living"
(DIDL) questionnaire was used to assess patients' satisfaction with their dentition and
impacts on daily living. The NEO five factor inventory (NEO-FFI) was used to assess
personality profiles.
14
RESULTS: The dentition had measurable impacts on daily living as well as satisfaction
with appearance, pain levels, oral comfort, general performance, and eating capability (p
< 0.001). Older patients were more totally satisfied (p = 0.014), more satisfied with
appearance (p = 0.034), and less satisfied with general performance (p = 0.024). Older
patients had higher Conscientiousness scores (p = 0.001) and lower Openness scores
(0.018). Females were more satisfied with eating (p < 0.001). Significant correlations
were established between neuroticism and total DIDL scores (p = 0.006). Extraversion
had significant correlations with total satisfaction (p < 0.001) as well as satisfaction with
appearance (p = 0.047) and oral comfort (p = 0.008). Significant correlations were also
established between openness and satisfaction with general performance (p < 0.001),
between Agreeableness and satisfaction with eating (p = 0.001), and between
Conscientiousness and total satisfaction (p = 0.001), satisfaction with pain (p = 0.004),
and satisfaction with oral comfort (p = 0.043).
CONCLUSIONS: The status of the oral cavity might impact on patients' daily living
and satisfaction with the dentition. Patients' satisfaction with their dentition has
definitive impacts on daily living and dental perceptions. Personality profiles
(neuroticism; extraversion; openness; agreeableness and conscientiousness) may
influence dental perceptions; play a significant role in shaping satisfaction with
dentition, and help with prediction of dental impacts on daily living. Patient satisfaction
and psychological profiles should be considered when formulating a treatment plan in
order to achieve patient acceptance of the offered treatment.

Level of education and gender-specific self-reported oral health behavior among
dental students.
Al-Omiri MK1, Barghout NH, Shaweesh AI, Malkawi Z.
Author information
Abstract
PURPOSE: To identify the oral health attitudes/behaviour among dental students in
Jordan, and analyse the variations in oral health attitudes based on gender and level of
education.
MATERIALS AND METHODS: Out of the 653 registered dental students at the
faculty of dentistry, 580 students (455 females and 125 males, mean age = 20.1 ± 1.6
years) participated in the study (response rate 89%). The Hiroshima University-Dental
Behavioural Inventory (HU-DBI) was used to assess oral heath attitudes and behaviour
of the participants. Data were analysed using the chi-square test, and statistical
significance was set at P < 0.05.
RESULTS: Females had better oral health attitudes and behaviour, especially towards
visiting the dentist, toothbrushing habits and oral hygiene practice (P < 0.05). Also,
students from the higher years had better oral health attitudes, behaviour and knowledge,
especially towards gingival health, oral hygiene practice, toothbrushing and visiting the
dentist (P < 0.05).
CONCLUSION: Dental students in Jordan had poor oral health attitudes and behaviour.
Females had better oral health knowledge, attitudes and behaviour than males. With
increasing years of study, some aspects of dental students' oral health behaviour and
attitudes improved. However, this improvement was limited and students should be
15
encouraged to become an example of oral health for their society. Better comprehensive
dental education with early exposure to dental health and prevention was suggested to
improve dental students' oral health attitudes and behaviour.

Psychological profiles in patients with recurrent aphthous ulcers.
Al-Omiri MK1, Karasneh J, Lynch E.
Author information
Abstract
The aim of this study was to investigate the psychological profiles of patients with
recurrent aphthous ulcers (RAUs). 50 patients (27 men and 23 women, mean age
31.44±9.95 years) with diagnosed RAUs participated in this study. 50 controls who
matched the patients in age and gender were also recruited. The participants' personality
and psychological profiles were assessed using the Hospital Anxiety and Depression
Scale (HAD) and the Neuroticism-Extraversion-Openness Five Factor Inventory (NEOFFI). Data analysis showed that females had higher HAD anxiety scores than males in
both patients and controls. Patients' age, intensity of pain and number, position, duration,
and frequency of ulcers had no relation to HAD and NEO-FFI scores. Patients reported
higher levels of anxiety in comparison to controls, but both reported comparable
depression scores. Patients' NEO-FFI scores were not different from those reported by
controls and the psychological profiles of patients and controls were similar. In
conclusion; stressful situations and conditions (i.e. anxiety) rather than personality
profiles and stable psychological traits were related to the occurrence of recurrent
aphthous ulcers.

Relationship between impacts of complete denture treatment on daily living,
satisfaction and personality profiles.
Hantash RO1, AL-Omiri MK, Yunis MA, Dar-Odeh N, Lynch E.
Author information
Abstract
OBJECTIVES: To investigate the association between satisfaction with conventional
complete denture prostheses (CDs), impacts of CDs on daily living and personality
profiles.
MATERIALS AND METHODS: Fifty-six patients (28 males and 28 females; mean
age 53.79 ± 7.762 years) with fitted upper and lower removable CDs were recruited for
16
this study. Clinical success of CDs was assessed according to specific clinical criteria.
The dental impact on daily living questionnaire (DIDL) was used to measure satisfaction
with CDs and their impacts on daily living. NEO five factor inventory (NEO - FFI) was
used to measure patients' personality profiles. Pearson correlation test and regression
models were used to analyze the collected data.
RESULTS: Females were more satisfied with appearance and less satisfied with eating
and scored higher on neuroticism, and lower on extraversion and openness personality
domains (p < 0.05). Older patients were more satisfied with appearance and less satisfied
with oral comfort and general performance (p < 0.05). Neuroticism, extraversion,
openness and agreeableness personality profiles could predict and had significant
relationship with CDs impacts on daily living and satisfaction with CDs.
CONCLUSION: Psychological profiles (e.g. neuroticism, extraversion, openness and
agreeableness) might play a role and explain CDs impacts on daily living and patients'
satisfaction with their oral status and CD treatment, therefore, might be used to predict
satisfactory outcomes of CD treatment. In this regard, technical aspects of CDs are less
essential when the prosthesis is clinically successful.
CLINICAL SIGNIFICANCE: Psychological factors may play a role and also provide
valuable information for the prediction of satisfactory outcomes of complete denture
treatment.

Variation in time of emergence of permanent teeth among urban and rural
Jordanian school children.
Shaweesh AI1, Al-Omiri MK, Alsoleihat FD.
Author information
Abstract
OBJECTIVE: To investigate the variation in time of permanent tooth emergence
between urban and rural Jordanian school children.
METHODS: In this observational cross-sectional study, 1900 pupils at urban schools,
and 772 at rural schools aged 5-16 years in both genders were examined for emergence
of permanent teeth at different urban and rural primary schools and kindergartens in
Jordan between March and June 2010. Probit analysis was used to estimate the median
age of emergence per permanent tooth.
RESULTS: The emergence ages for most of the permanent teeth were generally
advanced in urban schoolboys in contrast to their fellows at rural schools. However, the
differences were only statistically significant for the maxillary canine and maxillary
premolars. Compared with boys, schoolgirls had smaller variation in permanent tooth
emergence across school region, and none of the differences were statistically
significant.
CONCLUSION: Urban schoolboys have accelerated emergence of the maxillary canine
and maxillary premolars compared to rural boys. The potential etiology behind this
finding needs to be investigated further in the future.

Impacts of implant treatment on daily living.
Al-Omiri MK1, Hammad OA, Lynch E, Lamey PJ, Clifford TJ.
Author information
Abstract
PURPOSE: This study investigated the association between satisfaction with the
dentition and dental prostheses and personality profiles among patients who received
implant-supported prostheses.
MATERIALS AND METHODS: Patients seeking dental implant therapy were
recruited for this study. A Dental Impact on Daily Living questionnaire was used to
assess dental satisfaction and the effects of implant-supported prostheses on daily living.
The NEO Five Factor Inventory (NEO-FFI) was used to assess participants' personality
profiles. Participants completed the questionnaires before implant insertion and 3 months
after rehabilitation with implant-supported prostheses.
RESULTS: Eighty patients (42 men and 38 women, mean age 40.99 years) participated.
Patients were more satisfied with their dentition after implant treatment. Neuroticism and
conscientiousness had significant relationships with patient satisfaction and impact on
daily living both before and after implant therapy. Openness and agreeableness had
significant relationships with patient satisfaction and impact on daily living only after
implant treatment. Extraversion had a significant relationship with patient satisfaction
and impact on daily living only before treatment. After implant treatment, neuroticism
was helpful in predicting total satisfaction, as well as satisfaction with appearance, pain,
oral comfort, performance, and eating. Conscientiousness was helpful in predicting
satisfaction with appearance, whereas openness was helpful in predicting satisfaction
with pain. Before implant treatment, neuroticism was helpful in predicting total
satisfaction as well as satisfaction with appearance, oral comfort, and performance.
CONCLUSION: Implant-supported prostheses had positive impacts on participants'
daily living and satisfaction with the dentition. Personality traits (such as neuroticism,
openness, agreeableness, and consciousness) affect patients' daily living and satisfaction
with implant-supported prostheses. Selected personality traits might predict patients'
satisfaction with implant-supported prostheses prior to treatment.

Abstract
OBJECTIVE: The aim of this prospective clinical trial was to evaluate the incidence of
postoperative complications following surgical extraction of lower third molars (L8) and
the risk factors and clinical variables associated with these complications.
SUBJECTS AND METHODS: Three-hundred and twenty-seven consecutive patients
(128 men and 199 women, mean age = 23.1 ± 3.9 years, range: 18-40) were recruited to
this study. The L8 of all the patients were surgically extracted. Immediate and late
18
complications like pain, swelling, trismus, paresthesia, bleeding, dry socket, infection
and fracture were assessed 3 and 7-14 days, respectively, following the surgery.
RESULTS: The most frequent immediate and late complications were slight pain,
swelling, and trismus. Thirty-nine (11.9%) patients reported dry socket and 10 (0.3%)
reversible sensory nerve complications. More immediate and late complications were
experienced by females (p = 0.000 and 0.016, respectively). Older subjects reported
more late complications. Frequent immediate and late complications were associated
with preexisting pericoronitis, longer duration of operation, extraction of two molars,
flaps with vertical incision, extractions with bone removal, extractions without tooth
sectioning and distoangular impactions (p ≤ 0.05). Linear regression analysis showed
that the above factors were able to predict postoperative complications.
CONCLUSION: The most frequent immediate and late complications were slight pain,
swelling, and trismus. Preoperative complaints, angulation of the impacted molars,
duration of surgery, type of surgical flap, the need for bone removal and tooth sectioning
could predict and had an impact on the incidence of postoperative complications
following L8 removal. Females and older patients were likely to have more
postoperative complications following surgical extraction of L8.

Author information
Abstract
PURPOSE: The objective of this study was to investigate the relationship between
satisfaction with implant-supported fixed rehabilitations (ISFPR), their impacts on daily
living, and personality profiles.
MATERIALS AND METHODS: Fifty patients (15 men and 35 women; mean age 44.3
± 9 years), with fitted ISFPR, and 50 partially dentate controls matched with age and
gender participated in this study. A Dental Impact on Daily Living questionnaire was
used to assess dental satisfaction and impacts of ISFPR on daily living. NEO Five Factor
inventory was used to assess participants' personality profiles. Pearson correlation,
analysis of variance, and linear regression tests were used for statistical analysis of the
data.
RESULTS: Patients with ISFPR were more satisfied with their dentition than controls
(p < .05). Patients and controls demonstrated different relationships between personality,
impacts on daily living, and satisfaction. Neuroticism, extraversion, and
conscientiousness had significant relationships with satisfaction and impacts on daily
living in both groups (p < .05). Openness and agreeableness had significant relationships
with satisfaction and impacts on daily living in patients' group (p < .05).
CONCLUSION: ISFPR had positive impacts on participants' daily living and dental
satisfaction. Personality traits (neuroticism, extraversion, openness, agreeableness, and
consciousness) impact on daily living and satisfaction with ISFPR, and might predict
satisfaction with ISFPR and their impacts on daily living. © 2011 Wiley Periodicals, Inc.

Stress analysis of endodontically treated teeth restored with post-retained crowns: A
finite element analysis study.
Al-Omiri MK1, Rayyan MR, Abu-Hammad O.
Author information
Abstract
BACKGROUND: The authors conducted a study to analyze the stress concentration
areas in a tooth restored with a post-retained crown under various conditions.
MATERIALS AND METHODS: The authors constructed a three-dimensional finite
element model describing a maxillary second premolar restored with an all-ceramic
crown supported by a titanium post and a resin-based composite core. They applied
static vertical and horizontal loads of 100 newton to the cusp tip of the crown and
recorded Von Mises and tensile stress values. The variables investigated were the
presence of the post, coronal and apical post extensions, post diameter, post shape, and
post and core material.
RESULTS: The study results showed that horizontal loading generated higher levels of
stress than did vertical loading. The greatest stress levels were concentrated at the
cervical region and at the post-dentin interface in all models. Under both loads, a higher
modulus of elasticity of the post material and a wider post diameter were associated with
increased stress values at the post-dentin interface. Reduction of the post extension
above the level of bone was associated with increased dentinal stresses near the apex of
the post.
CONCLUSIONS: Although endodontic posts provide retention for coronal restorations,
they result in dentinal stress values higher than those of crowns without posts. Posts that
had a similar modulus of elasticity to dentin and smaller diameters were associated with
better stress distribution. Resting coronal restorations on sound dental tissues affected
stress distribution more than did the core material or the length of the coronal post
extension.
CLINICAL IMPLICATIONS: Many factors influence the distribution of stress within
dentin and, consequently, the fracture resistance of teeth restored with post-retained
crowns. Clinicians need to keep these factors in mind when performing endodontic
procedures that involve placement of post-retained crowns to ensure optimal success.

Fracture resistance of teeth restored with post-retained restorations: an overview.
Al-Omiri MK1, Mahmoud AA, Rayyan MR, Abu-Hammad O.
Author information
Abstract
INTRODUCTION: Posts have been used efficiently to retain restorations for badly
destructed teeth. This article critically analyzes the concerned topics related to the
fracture resistance of teeth restored with dowel-retained restorations.
METHODS: A systematic review of PubMed/MEDLINE, Cochrane, and Scopus
databases was completed (from 1960 to 2010). Single or combined key words were used
to obtain the most possible comprehensive list of articles. Checking the references of the
20
relevant obtained sources completed the review along with a manual search to locate
related articles on the topic. In vivo and ex vivo (laboratory, computer-based finite
element, and photoelastic stress analysis studies) investigations related to the topic were
included.
RESULTS: Many factors have been proposed to influence the fracture resistance of
post-restored teeth. Recognizing the significance of these factors on the fracture
resistance of teeth would aid in choosing the suitable treatment modality for every
individual case. Fracture resistance was improved if tooth structure loss was limited, a
ferrule was obtained, a post with similar physical properties to natural dentine was used,
and adhesive techniques for post luting and coronal restoration were used. Adhesively
luted resin/fiber posts with composite cores appear to be the best currently available
option in terms of tooth fracture and biomechanical behaviour.
CONCLUSIONS: Most guidelines were based mainly on ex vivo studies and to a lesser
extent on limited in vivo studies. The lack of long-term controlled randomized clinical
studies was the main hindrance to reaching a conclusive and undisputable opinion
regarding endodontic posts in terms of tooth fracture and biomechanical behaviour.

Antibiotic prescribing practices by dentists: a review.
Dar-Odeh NS1, Abu-Hammad OA, Al-Omiri MK, Khraisat AS, Shehabi AA.
Author information
Abstract
Antibiotics are prescribed by dentists for treatment as well as prevention of infection.
Indications for the use of systemic antibiotics in dentistry are limited, since most dental
and periodontal diseases are best managed by operative intervention and oral hygiene
measures. However, the literature provides evidence of inadequate prescribing practices
by dentists, due to a number of factors ranging from inadequate knowledge to social
factors. Here we review studies that investigated the pattern of antibiotic use by dentists
worldwide. The main defects in the knowledge of antibiotic prescribing are outlined. The
main conclusion is that, unfortunately, the prescribing practices of dentists are inadequate
and this is manifested by over-prescribing. Recommendations to improve antibiotic
prescribing practices are presented in an attempt to curb the increasing incidence of
antibiotic resistance and other side effects of antibiotic abuse. KEYWORDS:

Abstract
BACKGROUND AND OBJECTIVES: Narghile is becoming the favorite form of
tobacco use by youth globally. This problem has received more attention in recent years.
The aim of this study was to investigate the prevalence and pattern of narghile use
among students in three public Jordanian universities; to assess their beliefs about
narghile's adverse health consequences; and to evaluate their awareness of oral health
and oral hygiene.
METHODS: The study was a cross-sectional survey of university students. A selfadministered, anonymous questionnaire was distributed randomly to university students
in three public Jordanian universities during December, 2008. The questionnaire was
designed to ask specific questions that are related to smoking in general, and to narghile
smoking in specific. There were also questions about oral health awareness and oral
hygiene practices.
RESULTS: 36.8% of the surveyed sample indicated they were smokers comprising
61.9% of the male students and 10.7% of the female students in the study sample.
Cigarettes and narghile were the preferred smoking methods among male students
(42%). On the other hand, female students preferred narghile only (53%). Parental
smoking status but not their educational level was associated with the students smoking
status. Smokers had also significantly poor dental attendance and poor oral hygiene
habits.
CONCLUSION: This study confirmed the spreading narghile epidemic among young
people in Jordan like the neighboring countries of the Eastern Mediterranean region.
Alarming signs were the poor oral health awareness among students particularly
smokers.

Abstract
OBJECTIVES: The aim was to evaluate the awareness and implementation of the
Smoking Cessation Clinical Practice (SCCP) guidelines.
METHODS: A self-reported questionnaire based on the updated version of the SCCP
guidelines was completed by 422 healthcare providers (HCPs) including physicians,
dentists, dental hygienists and pharmacists recruited from both public and private sectors
in Jordan.
22
KEY FINDINGS: The majority of HCPs reported good smoking-cessation practices.
However, their awareness about the SCCP guidelines was inadequate. Approximately
68% of HCPs lacked knowledge of the 5As; about 74% lacked knowledge of the 5Rs of
the clinical guidelines for smoking cessation, which are the principal guidelines for
smoking intervention and motivation to quit smoking. Fortunately, about 70% of
participants from all groups examined and applied most of the steps in the guideline
spontaneously without previous knowledge of the guideline. This spontaneous practice
could be due to their vast practical experience, and the use of logic and/or basic
knowledge about smoking cessation. Compared to physicians, pharmacists and dental
hygienists showed significantly more frequent practice of most steps with patients
willing to quit smoking.
CONCLUSIONS: Jordanian HCPs showed good, spontaneous smoking-cessation
practice. However, this practice could have been better if HCPs had adequate awareness
of the SCCP guidelines.

Abstract
OBJECTIVES: This study aimed to evaluate the reliability of a new CAD-CAM Laser
scanning machine in detection of incisal tooth wear through a 6-month period and to
compare the accuracy of using this new machine against measuring tooth wear using tool
maker microscope and conventional tooth wear index.
METHODS: Twenty participants (11 males and 9 females, mean age=22.7 years,
SD=2.0) were assessed for incisal tooth wear of lower anterior teeth using Smith and
Knight clinical tooth wear index (TWI) on two occasions, the study baseline and 6
months later. Stone dies for each tooth were prepared and scanned using the CAD-CAM
Laser Cercon System (Cercon Smart Ceramics, DeguDent, Germany). Scanned images
were printed and examined under a toolmaker microscope (Stedall-Dowding Machine
Tool Company, Optique et Mecanique de Precision, Marcel Aubert SA, Switzerland) to
quantify tooth wear and then the dies were directly assessed under the microscope to
measure tooth wear. The Wilcoxon Signed Ranks Test was used to analyse the data.
RESULTS: TWI scores for incisal edges were 0, 1, and 2 and were similar at both
occasions. Scores 3 and 4 were not detected. Wear values measured by directly assessing
the dies under the tool maker microscope (range=517-656microm, mean=582microm,
and SD=50) were significantly more than those measured from the Cercon digital
machine images (range=132-193microm, mean =165microm, and SD=27) and both
showed significant differences between the two occasions.
CONCLUSIONS: Measuring images obtained with Cercon digital machine under tool
maker microscope allowed detection of wear progression over the 6-month period.
However, measuring the dies of worn dentition directly under the tool maker microscope
enabled detection of wear progression more accurately. Conventional method was the
least sensitive for tooth wear quantification and was unable to identify wear progression
in most cases. Copyright 2010 Elsevier Ltd. All rights reserved.

Abstract
OBJECTIVE: To construct and optimize a neural network that is capable of predicting
the occurrence of recurrent aphthous ulceration (RAU) based on a set of appropriate
input data.
PARTICIPANTS AND METHODS: Artificial neural networks (ANN) software
employing genetic algorithms to optimize the architecture neural networks was used.
Input and output data of 86 participants (predisposing factors and status of the
participants with regards to recurrent aphthous ulceration) were used to construct and
train the neural networks. The optimized neural networks were then tested using
untrained data of a further 10 participants.
RESULTS: THE optimized neural network, which produced the most accurate
predictions for the presence or absence of recurrent aphthous ulceration was found to
employ: gender, hematological (with or without ferritin) and mycological data of the
participants, frequency of tooth brushing, and consumption of vegetables and fruits.
CONCLUSIONS: Factors appearing to be related to recurrent aphthous ulceration and
appropriate for use as input data to construct anns that predict recurrent aphthous
ulceration were found to include the following: gender, hemoglobin, serum vitamin B12,
serum ferritin, red cell folate, salivary candidal colony count, frequency of tooth
brushing, and the number of fruits or vegetables consumed daily.

Relationship between patients' oral health-related quality of life, satisfaction with
dentition, and personality profiles.
Karasneh J1, Al-Omiri MK, Al-Hamad KQ, Al Quran FA.
Author information
Abstract
AIM: The aim of this study was to investigate the relationship between patients' oral
health-related quality of life, satisfaction with their dentition, and their personality
profiles.
METHODS AND MATERIALS: Eighty-four patients (30 males and 54 females; mean
age 31.9+/-12.7 years) seeking routine dental treatment were recruited for this study. A
"Dental Impact on Daily Living" (DIDL) questionnaire was used to assess dental
satisfaction and impact on daily living. An "Oral Health Impact Profile" (OHIP) was
used to measure self-reported discomfort, disability, and dysfunction caused by oral
conditions. Oral health-related quality of life was assessed using the "United Kingdom
Oral Health Related Quality of Life" measure (OHQoL-U.K). A "NEO Five Factor
inventory" (NEO-FFI) was used to assess personality profiles.
24
RESULTS: The dentition has a measurable impact on daily living as well as with
satisfaction with appearance, pain levels, oral comfort, general performance, and eating
capability (p=0.000). Younger patients had more profound oral health impacts (p=0.045)
and higher neuroticism scores (0.043). OHIP scores were significantly related to
OHQoL-UK scores (p=0.000). DIDL scores had significant correlations with OHIP and
OHQoL-UK scores (p<0.05). Significant correlations were established between
neuroticism and satisfaction with oral comfort, extraversion and total satisfaction and
satisfaction with general performance, and openness and satisfaction with appearance
(p<0.05). OHIP and OHQoL-UK scores had no significant correlations with
psychological profiles.
CONCLUSION: The status of the oral cavity can have a definitive impact on patients'
daily living and quality of life regardless age, gender, and level of education. Patients'
satisfaction with their dentition has definitive impacts on daily living, quality of life, and
dental perceptions. Personality profiles (neuroticism; extraversion, and openness) may
influence dental perceptions, play a significant role in shaping satisfaction with dentition,
and help with the prediction of the dental impact on daily living.
CLINICAL SIGNIFICANCE: Since patients' satisfaction with their dentitions impacts
their daily living and quality of life while affected by their psychological profiles, this
should be considered when formulating a treatment plan for management for their
dentition in order to obtain patient acceptance of the proposed treatment.

Relationship between oral health-related quality of life, satisfaction, and personality
in patients with prosthetic rehabilitations.
Al-Omiri MK1, Karasneh J.
Author information
Abstract
PURPOSE: This study investigated the relationship between oral health-related quality
of life, satisfaction with dentition, and personality profiles among patients with fixed
and/or removable prosthetic rehabilitations.
MATERIALS AND METHODS: Thirty-seven patients (13 males, 24 females; mean
age 37.6 +/- 13.3 years) with fitted prosthetic rehabilitations and 37 controls who
matched the patients by age and gender were recruited into the study. The Dental Impact
on Daily Living (DIDL) questionnaire was used to assess dental impacts on daily living
and satisfaction with the dentition. The Oral Health Impact Profile (OHIP) was used to
measure self-reported discomfort, disability, and dysfunction caused by oral conditions.
Oral health-related quality of life was assessed by the United Kingdom Oral HealthRelated Quality of Life (OHQoL-UK) measure. Moreover, the NEO five-factor
inventory was used to assess participants' personality profiles.
RESULTS: Prosthetic factors had no relationship to the DIDL, OHIP, and OHQoL-UK
scores. Patients with the least oral health impacts had better oral health-related quality of
life (p= 0.023, r =-0.37), higher levels of total satisfaction, and satisfaction with
appearance, pain, oral comfort, general performance, and eating (p < 0.05, r =-0.79, 0.35, -0.59, -0.56, -0.58, and -0.50, respectively). Patients with better oral health-related
quality of life (QoL) had higher total satisfaction, satisfaction with oral comfort, general
25
performance, and eating (p < 0.05, r = 0.34, 0.39, 0.33, and 0.37, respectively). Patients
with lower neuroticism scores had less oral health impact (p= 0.006, r = 0.44), better oral
health-related QoL (p= 0.032, r =-0.35), higher total satisfaction, satisfaction with
appearance, pain, oral comfort, and eating (p < 0.05, r =-0.58, -0.35, -0.33, -0.39, and 0.35, respectively).
CONCLUSION: Patients' satisfaction with their dentition and prosthetic rehabilitations
has positive effects on oral health-related QoL and oral health impacts and improves
patients' daily living and dental perceptions. Neuroticism might influence and predict
patients' satisfaction with their dentition, oral health impacts, and oral health-related
QoL. Satisfaction with the dentition might predict a patient's level of neuroticism.

The relationship between personality traits, pain perception and attitude toward
orthodontic treatment.
Abu Alhaija ES1, Aldaikki A, Al-Omairi MK, Al-Khateeb SN.
Author information
Abstract
OBJECTIVE: To investigate the relationship between personality traits and a person's
attitude toward orthodontic treatment and perception of pain during orthodontic
treatment.
MATERIALS AND METHODS: The sample consisted of two groups: group 1
consisted of 200 untreated subjects (100 males, 100 females; average age, 21.50 +/- 3.35
years), and group 2 consisted of 200 treated subjects (100 males, 100 females; average
age, 20.92 +/- 2.48 years). The instrument for data collection was a questionnaire that
included assessment of patients' personality profiles, pain expectation for untreated
subjects, pain experience for treated subjects, and attitudes toward orthodontic treatment.
RESULTS: Gender, treatment status, and personality traits did not affect subjects'
average attitude toward orthodontic treatment, whereas gender was the only variable that
affected subjects' average pain perception (P < .01). The average attitude score in
subjects who experienced pain during orthodontic treatment was 5.06 +/- 1.43, compared
to 4.32 +/- 1.35 for subjects who did not experience pain (P < .001). The average pain
perception scores in treated subjects with previous knowledge of orthodontic treatment
was 5.29 +/- 1.94, compared to 6.07 +/- 1.95 in subjects who did not have previous
knowledge of orthodontic treatment (P < .01).
CONCLUSIONS: Personality traits did not affect attitude toward orthodontic treatment
and pain perception/experience during orthodontic treatment. A more positive attitude
was found in patients who experienced less pain during orthodontic treatment

Impacts of missing upper anterior teeth on daily living.
Al-Omiri MK1, Karasneh JA, Lynch E, Lamey PJ, Clifford TJ.
Author information
Abstract
BACKGROUND: Aesthetics and function of the orofacial region are very important
aspects of human life which may be affected by tooth loss and impact on the quality of
26
life. The aim of this study was to identify the effects of anterior tooth loss on patients'
quality of life and satisfaction with their dentition.
METHODS: Fifty partially edentulous patients with missing anterior teeth and 50
control subjects who had no missing teeth were recruited into the study. The control
subjects matched the patients by age, gender, and level of education. A Dental Impact on
Daily Living questionnaire was used to assess dental impacts on daily living and
satisfaction with the dentition.
RESULTS: Tooth loss has a definite measurable impact on patients' daily living and
satisfaction with their appearance, pain levels, oral comfort, general performance, and
eating capacities (p = 0.000). Age and level of education had no effect on patients' total
satisfaction with their dentition and daily living. However, females were less satisfied
with appearance, general performance and eating (p = 0.003, 0.005 and 0.007
respectively) than males. There were significant correlations between the number of
missing anterior teeth and patients' total satisfaction (p = 0.028) and patients satisfaction
with appearance, oral comfort, general performance, and eating dimensions (p = 0.001,
0.048, 0.011 and 0.009 respectively).
CONCLUSION: Tooth loss has definitive impact on patients' satisfaction with their
dentition regardless of personal factors such as age, gender and level of education. The
higher the number of missing teeth the lower the levels of satisfaction with the dentition
and daily living.

Dental anxiety among university students and its correlation with their field of
study.
Al-Omari WM1, Al-Omiri MK.
Author information
Abstract
OBJECTIVE: This study was designed to investigate the subjective ratings of dental
anxiety levels among university students enrolled at Jordan University of Science and
Technology. In addition, the present study aimed to explore the sources of dental anxiety
and the impact of gender on the perceived dental anxiety and the correlation between
field of study and dental anxiety level.
MATERIAL AND METHODS: The Modified Corah Dental Anxiety Scale was used
to measure dental anxiety among the study population. Six hundred subjects were
recruited into the study from Jordanian undergraduate students from the faculties of
Medicine, Engineering, and Dentistry.
RESULTS: Five hundred and thirty five complete questionnaires were returned, which
accounts for a response rate of 89.2%. The totals of the mean anxiety scores were the
following: Medical students, 13.58%; Engineering students, 13.27% and dental students,
11.22%. About 32% of the study population has scored 15 or more. Dental students had
the lowest percentage of those who scored 15 or more. Surprisingly, the medical students
were responsible for the highest percentage of those who scored 15 or above. Although
women demonstrated statistically higher total dental anxiety scores than men (p= 0.03),
the difference between both genders was small and could be clinically insignificant. The
students were anxious mostly about tooth drilling and local anesthetic injection.
27
CONCLUSIONS: Lack of adequate dental health education may result in a high level
of dental anxiety among non-dental university students in Jordan. Further studies are
required to identify the correlates of dental anxiety among university students.

Al-Wahadni AM1, Hamdan S, Al-Omiri M, Hammad MM, Hatamleh MM.
Author information
Abstract
OBJECTIVES: The objective of this study was to investigate fracture resistance and
mode of failure of teeth restored with different prefabricated post systems.
STUDY DESIGN: Thirty teeth were collected, sectioned 15 mm from the apex, root
canal prepared, and randomly allocated into 3 groups as follows: glass fiber posts (group
1), carbon fiber posts (group 2), and Radix-Anchor titanium posts (group 3). Teeth were
then restored with a composite core and tested using a universal testing machine at 10
mm/min cross-head speed. Mode of failure was identified as either reparable or
irreparable (catastrophic).
RESULTS: Mean values of fracture forces (N) for teeth restored with Radix posts
(571.6) were statistically significantly higher than teeth restored with either carbon fiber
(420.6) or glass fiber posts (393.9). There were 86.67% of fractures that were
catastrophic in nature.
CONCLUSIONS: Teeth restored with Radix-titanium posts were more resistant to
fracture than those restored with either carbon or glass fiber posts. Most of the fracture
modes were catastrophic in nature.

practitioners.
Mansour YF1, Al-Omiri MK, Khader YS, Al-Wahadni A.
Author information
Abstract
AIM: The aim of this study was to evaluate the clinical performance of IPS-Empress
2(R) all-ceramic crowns placed by general dental practitioners.
METHODS AND MATERIALS: Eighty-two IPS-Empress 2 crowns placed in 64
patients (27 females and 37 males) were evaluated. These crowns had been in place for
15.2 to 57.2 months (mean 25.3 months, SD=9.3). Survival analysis was conducted
using the Kaplan-Meier method.
RESULTS: Of the 82 crowns 93.9% were rated satisfactory. In terms of the integrity of
the restorations, fracture was observed in three crowns and two showed a crack upon
transillumination. Five crowns were rated unsatisfactory for color match; one for
marginal adaptation; and none for discoloration, secondary caries, or sensitivity.
CONCLUSIONS: IPS-Empress 2(R) is a suitable material to fabricate all-ceramic
crowns; when these all-ceramic crowns were inserted by general dental practitioners,
28
they functioned satisfactorily with low failure rates during an observation period ranging
between 15.2 to 57.2 months.

Abstract
This study was undertaken to identify whether personality traits had any relationship with
patients' satisfaction with their dentition in tooth wear cases. One hundred tooth wear
patients and one hundred controls were recruited into the study. A Dental Impact on
Daily Living questionnaire was used to assess impact of tooth wear on day to day life and
satisfaction with the dentition. An ordinal scale was used to assess tooth wear severity in
tooth wear patients. The NEO Five Factor inventory was used to assess personal profiles.
Tooth wear patients were less satisfied with their dentition, had higher Neuroticism,
lower Extraversion, and higher Openness than the controls.

Lack of association between periodontal parameters and preeclampsia.
Khader YS1, Jibreal M, Al-Omiri M, Amarin Z.
Author information
Abstract
29
BACKGROUND: It was hypothesized that periodontal diseases may increase the risk of
preeclampsia. To test this hypothesis, this study was conducted to determine the
association between periodontal parameters and preeclampsia among women in the north
of Jordan.
METHODS: A case-control study was conducted among women who gave birth at
Princes Badea Teaching Hospital between September 2004 and May 2005. A total of
115 preeclamptic women and 230 randomly selected controls were analyzed. The
number of teeth, restorations, decayed tooth surfaces, and clinical periodontal parameters
were determined within 24 hours after delivery. Information regarding participants'
demographics, antenatal history, and family history were collected through personal
interviews.
RESULTS: After adjustment for potential confounding factors, there were no statistical
differences between preeclamptic cases and normotensive controls with regard to mean
periodontal probing depth, mean clinical attachment loss, mean gingival recession, mean
plaque index, and mean gingival index. In addition, there were no significant differences
in the percentages of sites with periodontal probing depth >/=3 or >/=4 mm, percentages
of sites with clinical attachment loss >/=3 mm, number of filled surfaces, and number of
missing teeth. Only the number of decayed surfaces was found to be associated with
increased odds of preeclampsia (adjusted odds ratio of 1.13; 95% confidence interval of
1.02 and 1.25).
CONCLUSION: This study did not support the hypothesis of an association between
periodontal parameters and preeclampsia.

An ex vivo study of the effects of retained coronal dentine on the strength of teeth
restored with composite core and different post and core systems.
Al-Omiri MK1, Al-Wahadni AM.
Author information
Abstract
AIM: To investigate the fracture resistance and fracture patterns of teeth restored with
composite cores supported by different pre-fabricated post systems and different heights
of remaining coronal dentine.
METHODOLOGY: Four groups of 30 single rooted teeth were used. Each group was
divided into three subgroups of 10 teeth each and restored with carbon fibre, glass fibre,
or Radix titanium posts luted with dual cure resin cement. The control group A had no
retained coronal dentine. Groups B, C and D had 2, 3 and 4 mm of retained buccal and
lingual coronal dentine, respectively. Teeth were tested to failure using an Instron
Universal Testing Machine. Subsequently, the fracture mode of specimens was recorded.
RESULTS: Teeth with retained dentine were more resistant to fracture (P = 0.001).
Tooth fracture resistance was not significantly different between groups B, C and D.
30
Within group A, titanium posts were associated with higher fracture resistance than fibre
posts. Within the other groups, tooth fracture resistance was not related to post material.
Within groups C and D, fracture resistance of teeth restored with carbon fibre posts was
significantly higher than those restored with glass fibre posts. The dominant fracture
mode in group A was core and vertical oblique root fracture whilst a combination of
core, coronal dentine and root fracture occurred in the other groups.
CONCLUSIONS: Fracture resistance of teeth increased with the presence of retained
coronal dentine. The use of glass and carbon fibre posts did not improve the fracture
resistance or the fracture pattern of teeth when compared with metal titanium posts
regardless of the presence of retained coronal dentine. The dominant fracture pattern of
teeth was not related to the amount of retained dentine if it was >2 mm high.

Factors affecting patient satisfaction after orthodontic treatment.
Al-Omiri MK1, Abu Alhaija ES.
Author information
Abstract
The objective of this study was to identify factors that may affect patients' satisfaction
with their dentition after orthodontic treatment. Fifty patients (20 males and 30 females;
mean age 20.7 +/- 4.2 years) who successfully had finished fixed orthodontic treatment
were included in the study. All subjects were treated with upper and lower fixed
orthodontic appliances for an average duration of 19 +/- 4 months and were in retention
stage (6-12 months) with upper Hawley and lower fixed bonded retainers. Dental Impact
on Daily Living questionnaire was used to assess the effect of orthodontic treatment on
daily living and satisfaction with the dentition in the study sample. The NEO Five Factor
inventory was used to assess personality profiles in the study sample. Comparisons
between groups were made using chi-square test. Personality traits were found to be
correlated with patients' satisfaction with their dentition after orthodontic treatment.
Higher neuroticism scores had a significant negative relationship with total satisfaction
with the dentition (P < .05). Age, sex, and pretreatment orthodontic treatment need had
no relationship with the patient's satisfaction. Patients treated nonextraction showed more
dissatisfaction with their dentition (P < .05). In orthodontically treated patients, higher
neuroticism scores were associated with lower levels of satisfaction with the dentition.

Author information
Abstract
31
OBJECTIVES: The literature has shown that patients' satisfaction with dental
prostheses is associated with the existence of certain personality profiles. It is important
to study such relationships in dental implant patients.
MATERIAL AND METHODS: Fifty patients (28 men and 22 women), aged between
22 and 71 years (mean age 43.22 years, SD 12.24 years), who were partially edentulous
and were seeking dental implant therapy were entered into this study. The patients were
requested to answer two reliable and valid questionnaires--the Dental Impact on Daily
Living (DIDL) and the Neuroticism Extraversion Openness Five-Factor Inventory
(NEO-FFI)--before implant treatment and 2-3 months after prosthodontic rehabilitation
therapy.
RESULTS: Certain personality traits were found to have a significant relationship with
patients' satisfaction with dental implants both before and after implant therapy (P <
0.05). Neuroticism score had valuable features in predicting patients' total satisfaction
ratings (P = 0), satisfaction with appearance dimension (P = 0), satisfaction with oral
comfort dimension (P = 0.005) as well as satisfaction with general performance
dimension (P = 0).
CONCLUSION: Personality traits have an impact on patients' satisfaction with dental
implant therapy. In addition, personality traits provide valuable information for the
prediction of patients' satisfaction with their implant-supported prostheses. Neuroticism,
openness, agreeableness and consciousness are very helpful in this regard. Neuroticism
was found the main predictor of the patients' oral health-related quality of life following
implant treatment.

Oral health attitudes, knowledge, and behavior among school children in North
Jordan.
Al-Omiri MK1, Al-Wahadni AM, Saeed KN.
Author information
Abstract
The aim of this study was to assess the knowledge, attitude, and behavior of school
children towards oral health and dental care as well as to evaluate the factors that
determine these variables. School children (n=557) of an average age of 13.5 years
attending public schools in North Jordan were recruited into this study. The subjects
completed a questionnaire that aimed to evaluate young school children's behavior,
knowledge, and perception of their oral health and dental treatment. The participants' oral
hygiene habits (such as tooth brushing) were found to be irregular, and parents' role in the
oral hygiene habits of their children was limited. The study population showed higher
awareness of caries than periodontal conditions. Irregular visits to the dentist were found
to be common, and toothache was the major driving factor for dental visits. Children had
positive attitudes toward their dentists; nevertheless, they indicated that they feared dental
treatment. The children in this study also recognized the importance of oral health to the
32
well-being of the rest of the body. Parents were not proactive in making sure that their
children received regular dental care. Parents' knowledge and attitudes about the
importance of oral health care and their fears about dental treatment influenced their
children's dental care. The results of this study indicate that children's and parents'
attitudes toward oral health and dental care need to be improved. Comprehensive oral
health educational programs for both children and their parents are required to achieve
this goal.

Abstract
Recent years have witnessed a consistent trend toward the introduction of patient
assessment of different treatment outcomes in dental practice. Patient satisfaction with
dental implants was considered among these treatment modalities. Few literature reviews
have been published on this topic. This article critically analyzes the concerned topics
related to patient satisfaction with dental implant. A MEDLINE search was completed
from 1983 to 2004, along with a manual search, to locate related articles on the topic.
Dental implants provided promising and predictable results regarding patient satisfaction
and various aspects of life assessment.

Differences in self-reported oral health behavior between dental students and dental
technology/dental hygiene students in Jordan.
Al-Wahadni AM1, Al-Omiri MK, Kawamura M.
Author information
Abstract
The aim of this study was to compare differences in oral health behavior between dental
students and dental technology/dental hygiene students in Jordan. One hundred and five
dental students and seventy-eight dental technology/dental hygiene students were
recruited into this study. All subjects were recruited from the students who were
receiving training at the clinics and laboratories that belong to the Faculty of Dentistry,
Jordan University of Science and Technology. The Hiroshima University-Dental
Behavioral Inventory (HU-DBI) was used to assess the oral heath behavior of the
subjects. Significant differences were found between students from different disciplines.
33
Dental students were found to worry more about visiting their dentist, to be less aware of
bleeding gums when brushing and were less bothered by the color of their gums
compared with dental technology and dental hygiene (DT/DH) students (P < 0.05, P <
0.001 and P < 0.05, respectively). Dental students tended to be more professionally
educated about brushing and to have a belief that they cannot clean their teeth well
without using toothpaste (P < 0.01 and P < 0.001, respectively). Most of them did not feel
they have brushed well unless they brush with strong strokes (P < 0.05). A logistic
regression model showed that it might be possible to distinguish dental students from
DT/DH students by using three items of the HU-DBI and the level of dental education.
The difference in the HU-DBI scores was not a major feature. There were significant
differences in oral health attitudes/behavior between dental students and DT/DH students.
The findings might reflect differences in students' training experience and education
between different specialties.

surgery. Jordan Medical Journal 2011, 45(2):167-173.
Abstract
Aim: The aim of this prospective clinical trial was to evaluate the reasons for removal of
miniplates from patients who had orthognathic surgery over a 7-year period. Materials
and Methods: Fifty consecutive patients with fixed miniplates following orthognathic
surgery (11 males and 39 females) aged 20 to 43 years old (mean=28±6 years) were
recruited into this study. Personal information, dental and medical history, type of
orthognathic operation, indications for plate removal, placement site of plates, and time
between insertion and removal were recorded. The site of plate insertion was classified
into right, left and anterior maxilla; right, left and anterior mandible; and chin. All plates
were inserted and removed intra-orally under local or general anesthesia. The association
between the variables was analyzed using the Pearson correlation and Chi-Square test.
For all statistical analysis, the significance level was set at P≤0.05. Results: 312 titanium
miniplates were inserted in 50 patients. A total of 108 plates (34.6%) were removed. The
retention period for the removed plates ranged from 4 months to 4.5 years. The most
common sites for plate removal were maxilla (22 patients, 44%) followed by mandible
(19 patients, 38%). The most common cause for plate removal was palpable plates (27
patients) followed by infection (13 patients), patient discomfort and preference (7
patients), and plate exposure and wound dehiscence (3 patients). No significant
relationships between plate removal (including number and location of removed plates
and reason for plate removal) and age and gender (p<0.05). Reason of plate removal was
significantly related to number of palates (p=0.001, r=0.441) and location of removed
plate (p≤0.001, r= 0.62). Type of removed plate had no significant relation with reason
for plate removal (p=0.576, r=-0.081), number of plates (p= 0.62, r= 0.072), and location
of removed plates (p= 0.467, r= -0.105). Reason for performing the orthognathic surgery
and type of the orthognathic surgery had no significant relations with number and
34
location of removed plates and reason for plate removal (p<0.05). Conclusions: Plate
removal was attributed to palpable plates, infection, subjective discomfort and patient
preference, and plate exposure and wound dehiscence. Plate-related complications caused
plate removal were more likely to occur within the first year of insertion. This should be
accounted for during the process of obtaining informed consent.

and post-surgical complications following removal of lower third molars. Jordan Journal
of Pharmaceuticals Sciences 2011;4(3):191-197.
Abstract
Aim: The aim of this prospective clinical trial was to evaluate the effects of antibiotic
therapy following different administration routes on the postoperative complications of
surgical removal of lower impacted third molars. Materials and Methods: Two hundred
and fourty eight consecutive patients (100 males and 148 females) aged 18 to 38 years
old (mean=24±5 years) were recruited into this study. The lower third molars of all
recruited patients were surgically extracted. Participants received preoperative antibiotic
cover either as intravenous Cephradine injection (1 gram) or oral dose of 500 mg
Cephalexin. Immediate and late complications following the surgery; including pain,
swelling, trismus, paraesthesia, bleeding, dry socket, infection and fracture of mandible;
were assessed 3 days and 7-14 days following the surgery. Results: The most frequent
complications were slight pain, swelling, and trismus. Oral route of antibiotic
administration was associated with more immediate and late complications (p<0.001).
Oral route of antibiotic administration was associated with more pain, swelling, trismus,
and dry socket (p<0.05). Conclusions: Following surgical extraction of third molars,
intravenous antibiotic administration was more effective in reducing the post surgical
complications than oral antibiotic administration.

and complications following surgical extraction of lower third molars. Jordan Medical
Journal 2011, 45(1):76-84.
Abstract
Aim: The aim of this prospective clinical trial was to evaluate the effects of antibiotic
therapy following different administration times on the postoperative complications of
surgical removal of lower impacted third molars. Materials and Methods: Three hundred
and twenty seven consecutive patients (128 males and 199 females) aged 18 to 40 years
old (mean=23.1±3.9 years) were recruited into this study. The lower third molars of all
recruited patients were surgically extracted. Participants received either intravenous
Velocef 1 gram or intra-oral 500 mg Cephalexin pre- (Group A, n=122), peri- (Group B,
n=70) or post-operatively (Group C, n=135). Immediate and late complications following
the surgery; including pain, swelling, trismus, paraesthesia, bleeding, dry socket,
infection and fracture of mandible; were assessed 3 days and 7-14 days following the
surgery. Results: The most frequent complications were slight pain, swelling, and
trismus. Most frequent complications were associated with post-operative antibiotic
administration and least complications were associated with pre-operative antibiotic
administration (p=0.000). Post operative administration of antibiotic was associated with
35
more pain (r=0.186, p=0.001), swelling (r=0.181, p=0.001), trismus (r=0.277, p=0.000),
and dry socket (r=0.335, p=0.000). Conclusions: Following surgical extraction of third
molars, preoperative antibiotic administration is more effective in reducing the post
surgical complications than peri-operative antibiotic administration which in turn is more
effective than post-operative antibiotic administration.

complications following dental implant surgery. Dirasat: Pure Sciences Journal, 2010;
38(1):10-14.
Abstract
Aim: The aim of this prospective clinical trial was to evaluate the post-operative healing,
complications, and implant success rate following the insertion of dental implants.
Materials and Methods: Eighty six consecutive patients (26 males and 60 females) aged
21 to 83 years old (mean=49.12±14.48 years) were recruited into this study. All patients
received dental implants under local anaesthesia, had pre-operative oral antibiotic cover
and used post-operative chlorhexidine mouth wash. Healing as well as immediate and
late complications following implant surgery; including pain, swelling, trismus,
paraesthesia, bleeding, infection and implant mobility; were assessed up to 1 year
following the surgery. Results: A total of 86 patients received 178 dental implants. The
most frequent immediate post operative complications included pain (96.5% of patients),
swelling (54.7% of patients), infection (1.2% of patients), and numbness (2.3% of
patients). Late post-operative complications included painful exposed mobile implants
with surrounding swelling and infection (8.1% of patients). Adequate healing was
observed in 171 implants and healing was improved with time. Seven implants failed,
resulting in a failure rate of 3.9%. The majority of implants (171 dental implants)
survived the entire study period giving a 96.1% implant survival rate. Age and gender
had no significant relations to implant failure, post-operative complications and healing
following implant insertion (p>0.05). Failed implants were associated with higher levels
of late (p<0.0001, r=1.0) and immediate post-operative swelling (p=0.012, r=0.271),
infection (p=0.001, r=0.364), and numbness (p<0.001, r=0.510). Less immediate postoperative complications were associated with better healing at recall intervals (p< 0.05).
Conclusions: Implant survival rate was very high in this report and exceeds 96%. The
most frequent reported complications in this study were pain, swelling, infection and
numbness. Certain factors including post-operative complications, type of implant, and
number of inserted implants affected implant survival rate. This should be considered
during planning for implant surgery in order to reduce post-operative complication and
thus improve the outcome of the provided treatment.

of Dental Bridge Supported by Natural Teeth. Part One: Varying the span of the bridge
restoring variable length saddles. An FEA Study. Alexandria Dental Journal 2006.
Abstract
Purpose: This study investigates the effect of reducing the number of abutment teeth
under bridges restoring saddles of different lengths on bone stresses under vertical and
horizontal loading. Materials and method: A number of three dimensional finite element
36
models were constructed describing teeth in upper right quadrant in a piece of bone
without third molar and with edentulous saddles of variable lengths. The bottom nodes
of the bone blocks in each model were restrained. Von-Mises stresses in the crestal bone
region of the model were recorded under separate vertical and horizontal loads. Results.
Von-Mises stresses were considerably high under vertical loading than under horizontal
loading. The more abutments supporting the bridge the lower the values of generated
stress. Stress values showed exceptionally high values under horizontal loading when
lateral incisor was the sole abutment on one side of the bridge. Conclusion. The more
abutments implemented in the support of the bridge, the less the resultant stresses under
vertical and horizontal loading. Teeth with small diameter should not be used as the sole
abutments for a bridge on any side unless values of occlusal loading onto the bridge can
be reduced by design or occlusal relief.

of Dental Bridge Supported by Natural Teeth. Part Two: Varying the location of the
edentulous saddles in the arch. An FEA Study. Alexandria Dental Journal 2006.
Abstract
Purpose: This study investigates the effect of varying the location of edentulous saddles
of varying lengths on bone stresses under horizontal loading. Materials and method: A 16
three dimensional finite element models were constructed describing teeth of the upper
right quadrant in a piece of bone without third molar. In each model a dental bridge was
constructed to restore an edentulous saddle. Extent of the restored edentulous saddles
varied between the models. Von-Mises stresses in the crestal bone region of the model
were recorded under separate vertical and horizontal loads. Results. The loss of more
teeth will result in higher bone stresses. The loss of the canine tooth produces higher
impact than the loss of other teeth of the same diameter. Conclusion. The canine’s unique
position at the corner of the arch renders its loss a direct cause for the occurrence of high
bone stresses. The longer the edentulous saddle, the higher the bone stresses.

Musculoskeletal Disorders among Jordanian Dentists. Jordan Medical Journal 2011;
45(2):1-10.
Abstract
Aims of the study: To investigate the prevalence of Musculoskeletal Disorders (MSDs)
symptoms (hand/wrist, neck, shoulder and back pain) among dentists and to identify the
risk factors associated with these symptoms. Methods: A random sample of 200 dentists
(114 males (mean age 40.6 years) and 86 females (mean age 40.1 years) were personally
interviewed using a structured questionnaire. The questionnaire assessed age, gender,
presence of MSDs, daily working hours, years of experience, working position,
participants’ knowledge of correct working posture and employment of dental surgeon
assistant. Data were processed and analyzed by Chi-square test. P value was set at ≤ 0.05.
Results: The majority of participants were general practitioners (87.5%). 86% of the
study sample suffered one or more of the MSDs (back pain (56%), neck pain (47%),
shoulder pain (39%) and hand/wrist pain (26%)). Females reported more shoulder pain
37
and less back pain than males (P=0.001). Neck, shoulder and back pain were significantly
increased among older dentists and dentists with more years of professional experience
(P≤0.0001). More than half of the participants were not aware of the correct working
postures (62.5%), the more the awareness of healthy postures the less the hand/wrist,
neck and back pain (P ≤ 0.05). Hand/wrist pain was most prevalent among dentists who
only worked while standing while least prevalent among dentists mixing between sitting
and standing postures (P≤0.0001). Conclusions: MSDs are common among Jordanian
dentists. There seems to be a substantial need for further training and continuing
education on occupational health among Jordanian dentists.

mandibular occlusal splint. Jordan Medical Journal 2012; 46(1):33-38.
Abstract
Objectives: The aim of this report was to describe the steps for construction steps of a
new design of mandibular occlusal splint, which was designed in a manner that facilitated
the engagement of the bilateral undercuts usually located on the lingual aspects of the
lower posterior teeth and alveolar processes.
Materials and Methods: This occlusal splint was composed of two parts. The split design
provided the flexibility needed to engage the deep bilateral undercuts located lingual to
the mandibular posterior teeth and alveolar processes.
The parts of the two splint segments were connected with flexible connectors made from
cast Ti-6Al-7Nb, an alloy characterized by its high flexibility (for the first part), and
wrought Cobalt-Chromium wire (for the second part of the splint). These flexible
connectors were expected to flex repeatedly each time the appliance was inserted or
removed from its position without undergoing permanent deformation.
Significance: The described occlusal appliance had the following merits: Since it had the
ability to engage the bilateral undercuts usually located lingual to the posterior segments
of the mandibular arch, this can abolish the need for any necessary block out and
eliminate the spaces between the appliance and the oral tissues. Such spaces can be
annoying for some patients because of the noticeable boarders or trapped food in case
that the appliance is used for eating as well. Undercut engagement also added to the
stability and retention of the appliance.
