Access to QDDOSS is targeted, quick, efficient, cost effective and free to patients in a safe primary care environment. Summary of clinical criteria for referral to QDDOSS Referrals accepted by QDDOSS: Patients who have General Medical Practitioners (GMPs) in the County Durham & Darlington area and who are 17 years or older Patients who fit into an ASA categories I and II (patients ASA III may be suitable for LA or Inhalational sedation (IHS/RA) – please contact QDDOSS to discuss individual cases if you are unsure. (ASA IV are NOT accepted) Extractions of special difficulty with associated pathology (such as ankylosis) for single and multi-rooted erupted teeth. Routine extractions will not be undertaken by this service. Removal of wisdom teeth as indicated by NICE (www.nice.org.uk March 2000, revised 26.4.04) Removal of buried roots and fractured or residual root fragments Removal of simple impacted/ectopic/supernumerary teeth (in conjunction with an orthodontic treatment plan) Exposure of teeth (removal of gum and or bone over the surface of the tooth preventing eruption) in conjunction with an orthodontic treatment plan Surgical endodontics on single rooted anterior teeth, which have a satisfactory orthograde root filling. A radiograph must be included with the referral. (NB re- RCT may be more appropriate and re-apicectomy is not usually indicated) Removal or enucleation of simple dental cysts. Benign minor soft tissue surgery including removal of simple fibro-epithelial polyps, mucoceles and denture induced hyperplasia (with no sinister features) Referrals NOT accepted by QDDOSS Soft tissue lesions of unknown nature/suspected malignancy – including red/white patches. Such cases need referral to acute trust +/- as 2WW referral Routine exodontias including failed LA Significant medical pathology i.e. ASA III and above Routine extractions for patients on anticoagulant therapy Please note: we offer treatment as clinically indicated under LA with or without IHS (RA) or IV (intravenous sedation). We do NOT offer a GA service. Any patients requiring GA will need appropriate referral to local Oral and Maxillofacial services. FROM JANUARY 2016 WE NO LONGER ACCEPT PAPER COPIES OF RADIOGRAPHS . DIGITAL RADIOGRAPHS ARE TO BE SENT VIA SECURE EMAIL TO [email protected], BY DISC OR THE ORIGINAL RADIOGRAPGH (FILMS) ARE TO BE SENT WITH THE REFERAL AND WILL BE RETURNED AT THE END OF TREATMENT. 3 Averley, Dorman, Hierons Queensway Dental Clinic November 2013 Patient Selection The service is for: All patients who have a GMP in the County Durham & Darlington area and who are 17 years or older referred by their primary care dental or medical practitioners. Patients who are healthy or have mild systemic disease with no functional limitation - for example, ASA II and I. Warfarinised patients can usually be managed in general dental practice and would not routinely be accepted by this service (Appendix 3), unless the treatment required meets the above clinical criteria. Patients requiring oral surgery treatment under local analgesia alone or in conjunction with conscious sedation. Treatment under general anaesthesia will not be provided by this service. All patients who fit these criteria should be referred to the Queensway County Durham & Darlington Oral Surgery Service (QDDOSS) in the first instance. Patients requiring more complex oral surgery treatment that do not meet the above described clinical criteria, or those being referred for care due to a complex medical history, should be referred to a secondary care setting. Patients with suspicious white/red patches (suspected cancer referrals) should be referred directly to the Acute Trust. This referral should be made via the two-week rule system. Patients will be assessed following referral from their general dental or medical practitioner. Patients, who meet the criteria for treatment in the primary care based intermediate oral surgery service, will be offered an appointment. Patients who do not meet the criteria specified above may be either referred on to secondary care or returned to the referring practitioner. Referral patterns will be audited and this may lead to individual discussion with referring practitioners if guidelines are not being followed. Please help the service to improve the care for your patients by providing a full assessment of the patient’s needs and including the following details: Relevant medical history e.g. prescription drugs, heart disease Relevant social history e.g. lives alone, does not have own transport, requires a translator (please state the language) Full description of the patient’s clinical condition and reason for referral Please ensure that relevant radiographs accompany all requests to avoid unnecessary radiation exposure to patients. These radiographs will be returned once treatment has been completed. 4 Averley, Dorman, Hierons Queensway Dental Clinic November 2013 Sedation Assessment Guidelines The American Society of Anaesthesiologists (ASA) - Classification of physical status, see below ASA I ASA II ASA III ASA IV ASA V Normal healthy patients ● No organic, physiological, biochemical or psychiatric disturbance Patients with mild to moderate systemic disease May be due to the condition or pathophysiological processes ● e.g. Well controlled asthma, NIDDM- dietary controlled, mild hypertension ● Also: no systemic disease but: extremely nervous (high levels of endogenous adrenaline and> risk of sedation complications), >65years (more sensitive to sedatives and physiology less responsive), obese (< respiratory capacity) Suitable for LA with or without IV sedation or Inhalational sedation Patients with severe systemic disease which is limiting but not incapacitating ● e.g. stable angina, well controlled epilepsy, chronic bronchitis, congestive heart failure, IDDM, healed MI. Patients with severe systemic disorders that are a constant threat to life ● e.g. recent MI, uncontrolled diabetes, uncontrolled epilepsy, severe emphysema – requiring O2 therapy, cardiac insufficiency etc. Moribund patients not expected to live more than 24hrs. ● Only emergency treatment would ever be provided, e.g. severe trauma. Suitable for LA with or without Inhalational sedation Should be managed in secondary care ASA guidelines in relation to BP – Malamed, 1995 BP mmHg <140 systolic & <90 diastolic 140 to 160 systolic & 90 – 94 diastolic 160 to 179 systolic & 95-104 diastolic 180 – 199 systolic & 105 – 115 diastolic >200 systolic & >115 diastolic ASA classification I II III a III b IV Classification of Body Mass Index (BMI ) - as adopted by WHO 2000 Classification Underweight BMI <18.5 Normal weight Pre-obese (overweight) Obese Class I Obese Class II Obese Class III 18.5-24.9 25.0-29.9 30.0-34.9 35.0-39.9 >40.0 Risk of non-communicable diseases Low (but risk of other clinical problems may be greater) Average Increased Moderate Severe Very Severe 5 Averley, Dorman, Hierons Queensway Dental Clinic November 2013 Fitness for sedation, based on ASA (FDJ 2010): ALL patients should be given an ASA grade at the time of assessment ASA grades & BMI Treatment modalities Appropriate setting I & II BMI up to 35 Local anaesthetic (LA) alone LA + Inhalational sedation (also known as IHS and RA) LA + Intravenous (IV) sedation QDDOSS: in surgery operatorsedationist care III BMI >35 Local anaesthetic (LA) alone LA + Inhalational sedation (also known as IHS and RA) May be suitable for QDDOSS – in surgery operatorsedationist care. Check on individual basis III BMI >35 LA + IV sedation Anaesthetic led sedation, in most cases will require Secondary Care NB: Maximum weight limit for dental chairs is 150kg Blood Pressure (BP) pre-assessment and day of treatment ● ● ● Risks relate to high diastolic values then subsequent use of adrenaline containing LA and possible further elevation. Cut-off for listing patients for operator-sedationist IV sedation 180/100 (i.e. within the ASA III a band taking into to consideration some degree of ‘white coat effect’). BP values >180/100 should be sent to their GP for monitoring or treatment as appropriate and follow-up appointment made 6-8 weeks later prior to listing. Patient asked to bring series of BP values from practice for our records. NB due to TIOSS time parameters patients may need to be re-referred. Day of treatment ● ● ● Pre-operative BP <180/100 – OK to proceed Pre-operative BP <180/<105 and normal pre-operative values/ readings from GP (‘white coat’ hypertension in non-medicated or medicated anxious patients) – consider proceeding with caution Pre-operative BP >180/105 – delay treatment and refer to GP for appropriate management Body Mass Index (BMI) & IV sedation (BMI is not an issue with IHS) ● ● ● ● Patients with BMI >35 are at severely increased risk of co-morbidities including undiagnosed sleep apnoea, cardiovascular and peripheral vascular disease. Cut-off at BMI 35 with caveat for clinical judgement for e.g. rugby players NB maximum weight for dental chairs is 150kg If in doubt any cases BMI >35 refer to secondary care. Patients with a BMI > 40 not suitable for primary care. Refer to appropriate secondary care facility OR offer treatment with LA or Inhalational sedation. Averley, Dorman, Hierons Queensway Dental Clinic November 2013 6 How to refer Please use the referral form for referral of QDDOSS cases, which can be found in on page 21 (also available as a separate PDF on the providers website with the summary of clinical criteria for QDDOSS). There are three providers of this service in the region – Queensway (Darlington and Ferryhill), Smiles (Bowburn) and Oasis (Darlington). All referrers must use the referral form, which can either be faxed or posted. These forms can be downloaded from the provider’s websites. Urgent referrals can be telephoned through, but will need to be followed through with a referral form. Please advise the patient you are making the referral to the service and the patient should expect to be contacted for arrangement of an assessment appointment (NOT treatment on the 1st visit). Medico-legally a reasonable ‘cooling off’ period after consent is signed is essential to ensure valid consent for any proposed procedure – hence treatment at the initial assessment appointment should be avoided. “A reasonable cooling-off period gives the patient a chance to reflect on their decision and seek advice. During this time, you may want to provide explanatory leaflets to support any discussion and to ensure that the patient is as informed about their treatment as possible”. http://www.theddu.com/press-centre/press-releases/dental-professionals-should-givepatients-a-cooling-off-period#sthash.qoZNzWyh.dpuf Contact details Queensway Address: Queensway Dental Clinic, 293 Yarm Road, Darlington, DL1 1BA Tel: 01325 381928 Fax: 01325 381865 e-mail: [email protected] If you require further information please contact Rebecca Hierons on 01325 381928. You can also obtain information on the Queensway website: http://www.queensway.co.uk. 7 Averley, Dorman, Hierons Queensway Dental Clinic November 2013 Tertiary care (hospital) oral surgery services Referrals in to the hospital acute trust should be made in cases where patients require more complex treatment than the clinical categories listed in the referral guidelines or where complex medical conditions require treatment in hospital (e.g. haemophilia, bleeding disorders etc.). 2-Week Rule Referrals: In cases where red or white patches need urgent investigation immediate referral should be made to the Acute Trust using the 2–week rule protocols. These patients should not be given the choice of referral into primary care, as it is inappropriate to see them there and may delay subsequent oncology treatment. Urgent referrals and out-of-hours care: There is a 24-hour on-call service at James Cook University Hospital for urgent referrals such as facial fractures, uncontrolled oral bleeding, and orofacial infections producing swelling, trismus or airway problems. To make enquiries to this service please telephone James Cook University Hospital on 01642 850850 and ask for a member of the on call Oral & Maxillofacial team. Do NOT give the patient a letter or ask them attend the department or Accident & Emergency without having spoken to the department. (Darlington Memorial Hospital has an A&E but no Oral and Maxillofacial Service on call facility). Fail to attend policy If your patient fails to attend their assessment appointment they will be contacted by letter or telephone and offered a second assessment appointment. If they fail to attend a second appointment and do not get in touch a third assessment appointment will not be offered. If your patient fails to attend a confirmed treatment appointment and they do not get in touch, a second treatment appointment will not be offered by this service. Averley, Dorman, Hierons Queensway Dental Clinic November 2013 8 Non-third molar exodontia The service does not provide a service for "routine" extractions in healthy patients. If a surgical approach is obviously necessary (e.g. retained roots, ankylosis, etc.) then a referral should be made. Indications for referral include: Associated pathology that needs to be submitted for histological examination (e.g. cysts). It is rare that a patient's medical history complicates the extraction to such an extent that it needs to take place within a specialist setting. If the reason for referral is a medical reason, the referral needs to be made to a hospital setting. We are unable to accept any referrals without good quality, relevant clinical radiographs showing the full extent of the tooth/teeth along with the surrounding structures. Please ensure that relevant radiographs accompany all requests or your referral form will be returned. These radiographs will be returned once treatment has been completed. Averley, Dorman, Hierons Queensway Dental Clinic November 2013 9 Apical surgery All teeth should be re-root treated with an adequate root filling well condensed and extending the full length of the canal prior to referral. Repeat root filling has a higher success rate than apicectomy and hence should be carried out. The success rate for re- apicectomy is very low and will not be carried out by the primary care service. The service will not accept referrals for apicectomies on multi-rooted teeth. All referrals need to be sent with an up-to-date radiograph to allow triage. Practitioners should undertake a full clinical assessment of their patient and provide the service with written details giving the clinical justification for the requirement to have an apicectomy. See Appendix 1 for more detail. More comprehensive guidelines for referral for apicectomy are available at: www.rcseng.ac.uk/dental/fds/clinical_guidelines. Although there are exceptions referrals should generally meet the following criteria to be accepted to undergo peri-apical surgery: Completed primary root canal treatment, whether crowned or not. Completed root canal RE-TREATMENT, particularly if the primary treatment appears radiographically sub-optimal (e.g. lack of adequate condensation or short of apex). Post removal should be performed to enable root canal re-treatment where risk to root structure is minimal. A satisfactory coronal restoration (preferably a permanent restoration) should be present to ensure good coronal seal of the root canal system. It is generally agreed that endodontic failures are best approached non- surgically by undertaking root canal re-treatment rather than peri-apical surgery 1,2,3. The success rates for apical surgery on molar teeth is low and will not routinely be undertaken. Repeat apicectomy has a low success rate and therefore will not routinely be undertaken 2,8. If a non-surgical approach (re-root treatment) is felt to be appropriate but it is not possible to meet these criteria in primary care, consideration should be given to referring the patient to an endodontic specialist. Averley, Dorman, Hierons Queensway Dental Clinic November 2013 10 Indications for peri-apical surgery – based on RCS guidelines: 4 These guidelines apply to cases when it is agreed that orthograde retreatment is either impossible or will not solve the problem. 1. Failure of initial and repeat conventional orthograde RCT – which appears radiographically satisfactory. 2. Gutta percha significantly through apex and associated with peri-apical pathology. 3. The presence of peri-radicular disease in a root filled tooth, where non-surgical root canal re- treatment cannot be undertaken or has failed, or where conventional retreatment may be detrimental to the retention of the tooth. 4. Physical barriers/anatomy – irremovable posts, fractured instruments, sclerosed canals (clinically and radiographically). 5. The presence of peri-radicular disease in a tooth where iatrogenic or developmental anomalies prevent non-surgical root canal treatment being undertaken. 6. The need for biopsy of the peri-radicular tissues – significant peri-apical pathology not resolving following satisfactory orthograde RCT (e.g. radiolucency greater than 1cm diameter). 7. The need to visualise the peri-radicular tissues and tooth root when perforation, root crack or fracture is suspected. 8. Fracture and infection of apical third (post traumatic). Contraindications to surgical endodontics 4 There are few absolute contraindications to endodontic surgery, these contraindications include: 1. Patient factors including presence of severe systemic disease and psychological considerations 2. Anatomical factors including: Unusual bony or root configurations Lack of surgical access Possible involvement of the neurovascular bundle An unrestorable tooth Poor supporting tissue 3. The skill, training and experience of the operator may also have an influence on decision making Averley, Dorman, Hierons Queensway Dental Clinic November 2013 11 Surgical Outcomes First apicectomy Success rates for apicectomies range from 30% (poorly root treated and inadequately restored) to 80% (well root treated and restored teeth) 5,6 One newer study using microscopy and MTA suggests a success rate up to 92% 7 Table to show comparison between first and repeat apicectomies: 2,8 Initial surgery: Second surgery; Success Uncertain 64.2% 25.7% Failure 15.75% Success Uncertain 35.7% 26.3% Failure 38% References 1.

There has been recent guidance issued related to the removal of teeth in dental practice for patients who are on warfarin (NPSA 2009). Patients should be managed according to these guidelines in general practice and not referred to the specialist services for "routine" extractions. The guidelines stipulate that extractions can safely be carried out in general practice in the following circumstances: when the INR is less than 4.0. if the socket is packed and sutured. Warfarin should not be stopped but the INR must be checked within 24 hours of the planned extraction (patients can usually co-ordinate this themselves with either their doctor or anticoagulant clinic). Patients should be referred to the hospital service if the patient is known to have one or more of the following: liver impairment/high alcohol intake renal failure thrombocytopoenia haemophilia other disorders of haemostasis is currently receiving chemotherapy is taking more than one antiplatlet drug if the INR is maintained at over 4 (this will be recorded in the patient's anticoagulant book). Extractions taking place in general practice should be timed appropriately and ideally should occur at the beginning of the week (such that delayed re- bleeding problems can be managed during the working week) and in the morning (such that immediate re- bleeding problems can be managed during the working day). Averley, Dorman, Hierons Queensway Dental Clinic November 2013 13 Bisphosphonate Related Osteonecrosis of the Jaw (BRONJ) Clinician and patient information notes What are Bisphosphonates? Bisphosphonates are a group of drugs mainly used for the treatment of osteoporosis (taken orally) but may also used in the treatment of cancer (given intravenously and in higher doses). These drugs affect the metabolism (turn-over) of bone. Examples of bisphosphonates include: alendronic acid (Fosamax), risidronate (Actonel), and zoledronic acid (Zometa). What is Osteonecrosis of the Jaw (ONJ)? ONJ is diagnoses clinically as the presence of exposed bone in maxillofacial region (upper or lower jaws) for more than 8 weeks in the absence of radiotherapy to the jaw. It is a rare condition, poorly understood, with increasing number of cases being seen and while there have been lots of publications their quality is limited. How likely is it to affect me? The risk of developing ONJ if taking oral bisphosphonates is between 1:10,000 and 1:100,000. For high dose intravenous Bisphosphonates (cancer treatment) the risk rises to 1:10 – 1:100. Antibiotics and ONJ The British and American Dental Associations (BDA and ADA) found no evidence for prophylactic antibiotics after surgical procedures. They recommend the use of antibiotics should be based on the risk of an infection rather than because the patient is taking a bisphosphonate. Use of Chlorhexidine mouth wash preoperatively and until the surgical site is fully healed may be helpful. Should bisphosphonates be stopped before invasive dental surgery? The BDA suggests assessing the clinical situation and discussion with the patient’s physician or oncologist before stopping bisphosphonate therapy. Canadian guidelines recommend interrupting bisphosphonate for 3-6 months for non-emergency invasive dental treatment, however, the half-life of bisphosphonates in the skeleton is high and evidence for this approach is only anecdotal.

Any invasive dental procedure ideally to be completed prior to commencing high dose therapy Non-urgent procedures preferably to be delayed for 3-6 months following interruption of bisphosphonate therapy Dental examination not required prior to initiating therapy if there is appropriate dental care and good oral hygiene Best managed with supportive care including pain control, treatment of secondary infection, removal of necrotic debris, and mobile sequestrate. Aggressive debridement is contraindicated 15 Antibiotic prophylaxis The National Institute for Health and Clinical Excellence (NICE) issued a clinical guideline on antibiotic prophylaxis against infective endocarditis (IE) in March 2008. In a significant change to current clinical practice, the guideline recommends that antibiotics to prevent IE should not be given to adults and children with structural cardiac defects at risk of IE who are undergoing dental and non-dental interventional procedures. IE is an inflammation of the inner lining of the heart, particularly affecting the heart valves, caused by bacterial or other infection. It may arise following bacteraemia in patients who have certain preexisting heart conditions (see list below). Although IE is a rare condition, with fewer than 10 people in every 100,000 developing it each year, it can be life-threatening. It has been accepted clinical practice to use preventive (prophylactic) antibiotics before dental and some non-dental procedures in people who are considered to be at risk of IE. However, the effectiveness of this treatment in humans has never been properly investigated and clinical practice has been dictated by clinical guidelines based on expert opinion. This guideline is based on the best available published evidence and a consensus of multidisciplinary, expert opinion within the Guideline Development Group (GDG). The guideline concludes that there is no consistent association between having an interventional procedure, dental or non-dental, and the development of IE and that the clinical effectiveness of antibiotic prophylaxis is not proven. The evidence also suggests that antibiotic prophylaxis against IE for dental procedures is not cost effective and may lead to a greater number of deaths through fatal anaphylactic reactions than not using preventive antibiotics. The guideline makes a number of key recommendations, including: Patients should not be offered antibiotics to prevent IE for any of the following procedures: dental procedures obstetric or gynaecological procedures, childbirth or procedures on the bladder or urinary system procedures on the gullet, stomach or intestines procedures on the airways, including ear, nose and throat and bronchoscopy Healthcare professionals should regard people with the following cardiac conditions as being at risk of developing IE: acquired valvular heart disease with stenosis or regurgitation valve replacement structural congenital heart disease, including surgically corrected or palliated structural conditions, but excluding isolated atrial septal defect, fully repaired ventricular septal defect or fully repaired patent ductus arteriosus, and closure devices that are judged to be endothelialised Averley, Dorman, Hierons Queensway Dental Clinic November 2013 16 previous IE hypertrophic cardiomyopathy. Healthcare professionals should offer people at risk of IE clear and consistent information about prevention, including: the benefits and risks of antibiotic prophylaxis, and an explanation of why antibiotic prophylaxis is no longer routinely recommended the importance of maintaining good oral health symptoms that may indicate IE and when to seek expert advice the risks of undergoing invasive procedures, including non-medical procedures such as body piercing or tattooing. People at risk of IE who are receiving antimicrobial therapy because they are undergoing a gastrointestinal or genitourinary procedure at a site where there is a suspected infection should be offered an antibiotic that covers organisms that cause IE. Investigate and treat promptly any episodes of infection in people at risk of IE to reduce the risk of endocarditis developing. The full guidance is available at www.nice.org.uk/CG064 Averley, Dorman, Hierons Queensway Dental Clinic November 2013 17 The 18-week rule Clock Starts An 18-week clock starts when any care professional or service permitted by an English NHS commissioner to make such referrals, refers to: a) a consultant led service, regardless of setting, with the intention that the patient will be assessed and, if appropriate, treated before responsibility is transferred back to the referring health professional or general practitioner; b) an interface or referral management or assessment service, which may result in an onward referral to a consultant led service before responsibility is transferred back to the referring health professional or general practitioner; An 18-week clock also starts upon a self-referral by a patient to the above services, where these pathways have been agreed locally by commissioners and providers and once the referral is ratified by a care professional. Upon completion of an 18-week referral to treatment period, a new 18-week clock only starts: a) when a patient becomes fit and ready for the second of a consultant-led bilateral procedure; b) upon the decision to start a substantively new or different treatment that does not already form part of that patient’s agreed care plan; c) upon a patient being re-referred in to a consultant-led; interface; or referral management or assessment service as a new referral; d) when a decision to treat is made following a period of active monitoring; e) when a patient rebooks their appointment following a first appointment DNA that stopped and nullified their earlier clock Clock Pauses A clock may be paused only where a decision to admit has been made, and the patient has declined at least two reasonable appointment offers for admission. The clock is paused for the duration of the time between the earliest reasonable offer and the date from which the patient makes themselves available again for admission. Averley, Dorman, Hierons Queensway Dental Clinic November 2013 18 Clock Stops for Treatment A clock stops when: a) first definitive treatment starts. This could be: i. treatment provided by an interface service; ii. treatment provided by a consultant-led service; iii. therapy or healthcare science intervention provided in secondary care or at an interface service, if this is what the consultant-led or interface service decides is the best way to manage the patient’s disease, condition or injury and avoid further interventions b) A clinical decision is made and has been communicated to the patient, and subsequently their GP and/or other referring practitioner without undue delay, to add a patient to a transplant list. Clock Stops for Non-Treatment An 18-week clock stops when it is communicated to the patient, and subsequently their GP and/or other referring practitioner without undue delay that: a) It is clinically appropriate to return the patient to primary care for any non consultant-led treatment in primary care b) A clinical decision is made to start a period of active monitoring; c) A patient declines treatment having been offered it d) A clinical decision is made not to treat e) A patient does not attend (DNA) their first appointment following the initial referral that started their 18 week clock, provided that the provider can demonstrate that the appointment was clearly communicated to the patient. 1 f) A patient DNA any other appointment and is subsequently discharged back to the care of their GP, provided that: i) the provider can demonstrate that the appointment was clearly communicated to the patient ii) discharging the patient is not contrary to their best clinical interests; iii) discharging the patient is carried out according to local, publicly available, policies on DNA. iv) these local policies are clearly defined and specifically protect the clinical interests of vulnerable patients (e.g. children) and are agreed with clinicians, commissioners, patients and other relevant stakeholders. 1 DNAs for a first appointment following the initial referral that started an 18-week clock nullify the patient’s clock (i.e. it is removed from the numerator and denominator for Referral to Treatment time measurement purposes). Averley, Dorman, Hierons Queensway Dental Clinic November 2013 19 Coronectomy – Information for patients and referring dentists Coronectomy is an alternative to extraction for a symptomatic impacted wisdom tooth when a tooth is deemed to be “high risk” of nerve injury (considerably more than the usually quoted 1% risk of numbness to lip or tongue) when a tooth is vital and the patient is medically well. The following is quoted from a paper by Professor Tara Renton (British Dental Journal 212, 323 - 326 (2012) Published online: 13 April 2012 | doi:10.1038/sj.bdj.2012.265): ‘A recent review of coronectomy procedures1 has brought to light the significant variance in thresholds for not only prescribing coronectomy, but the technique of delivering the procedure. Third molar surgery related to inferior alveolar nerve injury is reported to occur in up to 3.6% cases permanently and 8% cases temporarily.2, 3 Factors associated with inferior alveolar nerve injury (IANI) are age, difficulty of surgery and proximity to the IAN canal. If the tooth is closely associated with the IAN canal radiographically, 20% of patients having these teeth removed are at risk of developing temporary IAN nerve injury and 1-4% are at risk of permanent injury.2, 3, 4, 5, 6 Radiographic signs indicative of possible IAN risk include: • • • • • Diversion of the canal Darkening of the root Narrowing of the root/canal Interruption of the canal lamina dura Interruption of the juxta-apical area. If these plain film radiographic risk factors are identified, removal of the third molar will result in elevated risk of IANI (2% permanent and 20% temporary).3, 4, 5, 6 If the tooth is 'high risk', carious and/or the patient is medically compromised, the tooth must be extracted and the patient must be informed about the elevated risk of nerve injury’. The procedure involves a surgically removing the crown of the wisdom tooth and retaining the roots, but if during the course of the planned coronectomy the roots become loose the procedure will need to be converted to a standard extraction with the associated increased nerve injury risk. Warnings: 5% risk of dry socket (requiring rinsing and placement of an antiseptic dressing) and 2-5% need for a further procedure to remove the retained roots in the future (2-5 years after the original surgery).

The common problems are pain, swelling and infection. Your surgeon will have discussed the reasons for removal with you. Possible complications after treatment may include soreness, swelling, bruising and jaw stiffness. These can all be variable and can last from a couple of days to a couple of weeks. There is also a small risk of bleeding and post-operative infection, especially if you smoke. We recommend you abstain from smoking for at least 24hrs after tooth removal, but ideally for 3 days. If there is a large filling or crown in an adjacent tooth it is possible that this may be dislodged during surgery. Removal of Upper Molars (6’s, 7’s and upper wisdom teeth (8’s)) Occasionally the roots of these teeth are close to the big air sinus in your upper jaw (the antrum). This means that on removal there may be a small risk of a hole between your mouth and sinus (an oro-antral fistula or OAF). Your surgeon will discuss the degree of risk of this happening to you at your consultation appointment. If this happens your surgeon will close it up if appropriate. They would let you know, give you some antibiotics and decongestants and ask you not to blow your nose for 2 – 3 weeks to allow the hole to heal up. Removal of Lower Premolars (4’s & 5’s) These teeth are close to the mental nerve, which comes out of the lower jaw bone near the root tips and supplies feeling to your lower lip and chin. This means that there is a small risk of numbness, tingling or painful tingling of your lower lip and chin region after the procedure. This is normally temporary but can very rarely be permanent, although it rarely happens. Removal of Wisdom Teeth There is great variation in the difficulty of removing wisdom teeth. Some are easy, while others can be more complicated. At Queensway teeth can be removed under local anaesthesia (injection in the gum to numb the area), with or without sedation (laughing gas or an injection in the arm or hand to reduce anxiety) and your surgeon will discuss with you which method is most appropriate. The degree of difficulty of the surgery, any underlying medical conditions and other personal circumstances will be taken into account when choosing the best method for you. As well as the common post-operative complications mentioned above, wisdom teeth are situated close to two nerves, which give sensation to the lower lip and chin and to the tongue. This means that there is a risk of bruising or stretching of these nerves during removal of the teeth which may lead to numbness, tingling or painful tingling of your lower lip and chin region and/or tongue after the procedure. The degree of risk is related to the proximity of the wisdom tooth to these nerves, which your surgeon will discuss with you during your consultation. Most people are at low risk but sometimes the tooth can be very close to the nerves or may be especially difficult to remove – in which case, the risk is greater. If you have any questions about any aspect of your treatment please ask your surgeon who will be very happy to answer all your queries. Averley, Dorman, Hierons Queensway Dental Clinic November 2013 21 Instructions Following Oral Surgery Procedures Cleaning your mouth It is important to keep your mouth clean. On the first night do not rinse your mouth out but you should carefully brush the area. In the morning you may use a mouthwash or salt water. After one week you should carefully brush the sutures to accelerate their breakdown. Food & activity Stick with soft food until you can chew comfortably. Remember you have had a minor operation so take things easy. We advise time off work where necessary. (Sedation 24hrs) Mouth opening Mouth opening is usually restricted to about a fingers width between your front teeth for about a week after wisdom teeth extractions, it then slowly returns to normal. Stitches Your stitches are made of absorbable material and will disappear on their own. This can take many weeks(after 7 days gently brush with your toothbrush to break them down quicker) so if you are unsure or concerned telephone us for advice. Pain Dental operations can be painful. Afterwards we recommended that you use normal pain killers from the chemist for example Ibuprofen 400mg 3x per day (if you are able to take) with doses of paracetamol 1g 2- 3 hours later no more than 8 tablets (4g) per day i.e. alternate between the two pain killers (don’t take at same time). If you are not improving please contact us for a review appointment. Bruising This may appear on your face and neck. Do not worry it is quite normal and soon goes away. Swelling Your face may swell up for two days after certain operations. It will then take about five days to return to normal. If you are not improving please contact us for advice. Bleeding You may bleed from your mouth even though you have been stitched. Do not be alarmed. If the ooze becomes uncomfortable place a cotton handkerchief DIRECTLY over the operation site and bite firmly down for at least 20 minutes whilst remaining quietly seated. Do not rinse your mouth. Numbness After some operations your tongue or lip may be numb. This is only temporary but in some cases may last for an indefinite period. If you are numb, please avoid hot drinks and be careful eating, if numbness persists please contact us. Smoking: Please avoid smoking for at least 24 hours post – op but the longer the better!! If you have any concerns or problems please don’t hesitate to contact us on 01325 381928 – we will be pleased to help. Outside normal practice hours, telephone the practice on 01325 381928 and you will be given the dental oncall for further advice. If you have severe swelling please attend A&E at James Cook University Hospital and ask for the on-call doctor or Oral and Maxillofacial Surgery. Averley, Dorman, Hierons Queensway Dental Clinic November 2013 22 OAF instructions What is an OAF? OAF stands for an oro-antral fistula (opening) occurring in the upper back teeth region (maxillary). It is a small hole from the upper gum area into the cheek sinus which does not heal after a tooth has been extracted. What are the complications of an OAF? ● Air can pass through the opening into the soft tissues of the cheek causing a swelling (usually seen if patients stifle a sneeze or try to blow their nose). ● With large defects food can sometimes lodge in the sinus and liquid can come down the nose. ● If untreated in some cases the sinus itself can become infected, antibiotics may be prescribed as appropriate. How is an OAF treated? It can be closed by a minor oral surgery procedure either under local anaesthetic alone or in combination with sedation. The site is sutured (stitched closed) and the following advice is given: Post-operative advice: ● Avoid rinsing on the day of surgery to allow the wound to settle. The following day rinse regularly with warm salty rinses up to 4 times a day (one teaspoon of salt in a tumbler of cooling previously boiled water – take care not to burn yourself) for 5-7 days. ● Brush and clean the area carefully starting on evening of your treatment including around the stitches. ● It is important not to get air into the sinus (this can cause infection). It is very important not to blow your nose after surgery for at least 2 weeks (or longer if advised). ● A sneeze must not be stifled but allowed to happen naturally. ● You may be given a prescription for antibiotics (with or without a decongestant). You may also use menthol inhalations if you feel congested. You will be offered a review appointment in 2-3 weeks.

We would like to give you some information about all of the conscious sedation techniques available so that you are confident about giving us your permission (informed consent) to treat yourself or your child. 1. Treatment without local anaesthetic (numbing): Useful for check-ups, photographs, x-rays, scale and polish or preventative varnish application to teeth (procedures where there is no pain associated) 2. Topical anaesthetic and numbing: Topical anaesthetic gel is used on the gum, which causes some numbing of the gum so that only a very small scratch is felt when we fully anaesthetise the local area. This is used for the majority of procedures on patients who are not anxious. No pain is felt, however patients are fully awake and aware of what is happening. Standard Conscious Sedation Techniques: 3. Inhalation “Happy Air” Conscious Sedation: Nitrous oxide is mixed with oxygen to create a pleasant sedative air, which can be breathed in through the nose via a small soft nose hood. This is a similar technique to “gas and air” used for women during labour. This is an extremely safe technique that reduces the sensations of pain and anxiety, and creates a semi-hypnotic state for patients which makes them feel happy and comfortable. Patients will usually be aware of everything that is going on around them during the procedure but are more relaxed. Although patients are sedated during the procedure the recovery is fast with most patients feeling totally awake and in control within fifteen minutes after stopping the inhalation procedure. Therefore adult patients may not need an escort to accompany them. This technique is suitable for most adults and children with mild anxiety where only a small number of teeth need filling or extracting, or where the teeth to be treated are in the same area of the mouth. It may also be more suited to patients with needle phobias or patients with more complex general medical problems who may not be appropriate for intravenous conscious sedation. It is best not to eat for 2 hours before having inhalation sedation. 4. Intravenous Conscious Sedation: This is the most commonly used technique for patients aged over sixteen years, who are generally fit and well. It is usually delivered via a small plastic tube in the back of the hand or arm. A sedative medication called midazolam is given through this tube and the amount required is subject to each patient’s response. For patients who are anxious about needles we sometimes advise using inhalation conscious sedation to relax them and provide some pain relief prior to the injection and can also use EMLA cream to numb the back of the hand in advance, or ethyl chloride (cold numbing spray). Commonly patients receiving intravenous conscious sedation are more deeply sedated compared with inhalation conscious sedation. Most patients usually have significant memory loss of the procedure following intravenous conscious sedation, but some patients may remember small details of the procedure and a very small minority of Averley, Dorman, Hierons Queensway Dental Clinic November 2013 27 patients may have good memory of the events during the procedure. Unfortunately, we are unable to guarantee the level of amnesia as all patients respond differently to the medication. This technique is ideal for highly anxious patients, prolonged or more invasive procedures and procedures involving the treatment of multiple teeth at multiple sites. Patients require a suitable escort and should not be left alone for 24 hours after treatment and need to be starved for at least two hours prior to their appointment (unless informed otherwise by their dentist or anaesthetist). Referral for a General Anaesthetic in a Hospital Setting: The experienced team here always puts patients’ best interests first. A small number of patients are unsuitable for any of the above techniques discussed and would be more suitably managed within a hospital environment. The reasons for this would be discussed with you at your assessment appointment or in the event of our conscious sedation techniques being unsuccessful. In most cases it is advisable to try a conscious sedation technique prior to referral for a general anaesthetic. PLEASE NOTE THAT AT THIS DENTAL PRACTICE WE ARE UNABLE TO PROVIDE DENTAL TREATMENT UNDER GENERAL ANAESTHETIC - (PUT PATIENTS TO SLEEP). Remember – we are here to help and advise you. If there is anything in this information you are unsure of and would like some clarification then please ask a member of our team and we will be pleased to discuss any concerns you may have. Averley, Dorman, Hierons Queensway Dental Clinic November 2013 28 Information for Patients Having Intravenous Conscious Sedation Intravenous conscious sedation is a technique used by your dentist, which will help you to relax and alleviate anxiety during your treatment. It is usually given by a small injection in the back of the hand or arm. Unlike a general anaesthetic you will not be asleep, but will feel slightly drowsy during treatment and may continue to do so for several hours afterwards. The majority of patients remember very little of the treatment carried out under intravenous conscious sedation. It is important that the following rules are observed otherwise your sedation appointment may be cancelled: You MUST be accompanied by a responsible adult who MUST remain on the premises throughout your appointment, escort you home afterwards and arrange for you to be looked after for 24 hours after the procedure. Your escort MUST NOT be responsible for any other person except you on the day of your sedation, including young children and elderly relatives. Your escort MUST take you home after treatment by either private car or taxi rather than by public transport. You MUST NOT have anything to eat or drink for two hours prior to your appointment (unless you need a small glass of water to take your regular medication). Please remove any nail varnish and items of jewellery e.g. rings, watches prior to your visit as these may interfere with monitoring equipment. Please wear short sleeved, loose fitting and comfortable clothing for your appointment. If you are taking any medicines they should be taken at the usual times and should be brought with you so that the dentist may know what you have taken. Any illness occurring before the appointment should be reported immediately, as this may affect you treatment. You MUST NOT drive or operate machinery until 24 hours after sedation. You MUST NOT drink alcohol the night before and for 24 hours after sedation. You MUST NOT be solely responsible for young children for 24 hours after sedation and alternative child care arrangements should be made. You MUST NOT sign any legal documents until 24 hours after sedation. If you know or suspect you are pregnant please notify the practice as soon as possible – treatment under conscious sedation is best avoided during pregnancy. If you have any queries please phone the practice on 01325 381928 Averley, Dorman, Hierons Queensway Dental Clinic November 2013 29 Instructions For Persons Acting As Escorts For Patients Receiving Treatment Under Intra-venous Conscious Sedation Thank you for agreeing to act as an escort for your family member/friend when they have treatment under conscious sedation at this practice.
