Clinical Diagnostic
Procedures
Ch #4 Diagnosis & Tx Planning

Training in Basic Science enables:
– Perform diagnostic tests
– Interpret test results differentially
– Psychologically manage patient during
testing
– Formulate diagnosis and treatment plan.
Systematic Approach to
diagnosis

Should know when to consult and refer.
Systematic Approach to
diagnosis

Chief Complaint

First information obtained
Problem expressed in patient’s own words
Recorded in non-technical language

Dental History
Chief complaint
Present illness
Demographic data

Identify Pt characteristics
Medical History
There are no absolute C/I to
endodontics
 Endodontics is less traumatic than
extraction
 Older patients are in need of RCT
 Cases that need precautionary
measures
 When consultations are needed

Current Medications
List medications as presented by patient
 Review C/I and precautionary measures

Dental History
Pay attention to state of patient
 Ask probing questions
 Establish good rapport and caring
attitude.

Ascertain chief complaint
Take relevant medical and dental
history
Conduct thorough SubjectiveObjective- Radiographic examinations
1.Subjective Examination
Present Illness
 Pain
 Tentative diagnosis

Present Illness






Only if a patient has a sign problem
If no sign symptoms go on to objective tests
Pain may affect pt;s psychology
Dr must be open, caring, and interested to
elicit the most info
Ask further probing questions
Reiterate to the patient what they said in a
clear manner.
Pain

Intensity
– Intense
irreversible pathosis
– Recent, not long standing
– Unrelieved by analgesic
– Intermittent
– Irreversible pulpitis
– Acute apical periodontisits or abscess

Spontaneous pain
– Without eliciting stimulus
– Awakens patient
– May be relieved by cold
– Usually irreversible pulpitis

Continuous pain
– Lingering type of pain after removal of
stimulus
– Continuous pain with thermal stimulus=
irreversible pulpitis
– Continuous pain after application of
pressure = periradicular pathosis
Tentative diagnosis
Careful subjective questions
 Rule out non-odontogenic causes
 Urgency of treatment determined
 Confirmed or denied by hands-on oral
examination and clinical tests.


Clinical tests
Complex Process
 Tests of patients response!
 Presence of limitations
 May be inconclusive
 Supplementary confirmatory tests
needed
 False-neg + False-pos
 Control teeth

3.Radiographic examination

Periapical lesions (of odontogenic
origin):
– LD is lost apically
– Angulation does not change position
– Lucency resembles a hanging drop
– Usually cause of necrosis is evident
– Condensing ostietis- enostosis

Pulpal lesions
Special tests
Caries removal
 Selective anesthesia
 Transillumination
 Sinus tract tracing

Sample Clinical Notes
20 year old female patient
 CC: “ I have a swelling and broken
down tooth in my mouth” points to URQ
 Med Hx: Juvenile Diabetes – controlled
with medication (Insulin Injections
2X/day)
 Dent Hx: Several extractions, fillings,
and RCT

Pain: in URQ started 2 weeks ago,
wakes her up at night. Continuous,
throbbing, is not relieved by analgesics,
increases especially when drinking cold
and pain continues after removal of the
stimulus.
 EOE: NAD
 IOE: NAD tissues, large caries lesion in
#16


Tests: #16:
– Pain on perc + palp
– Severe lingering pain with Ice test (Endo
frost)
– Early response with EPT
– No pockets
– No mobiliy

Rad: small PA RL related to apex of #16
Diag: Irreversible pulpitis with chronic
PA periodontitis
 Tx plan: RCT, P+C, PFM Crown


Tx today:
– IDNB 2% lidocaine – 2 carpules
– Isolation
– Caries excavation
– Access
– Filing and irrigation
