The cost, effectiveness and cost effectiveness of removal and retention of asymptomatic, disease free third molars.
PURPOSE OF INVESTIGATION: The study was undertaken to identify the least costly, most effective and most cost-effective management strategy for asymptomatic, disease free mandibular third molars. METHODS AND PATIENTS: A decision tree model of the outcomes of mandibular third molar retention and removal was constructed. Probability data for possible outcomes were obtained from a comprehensive literature review and entered into the decision tree. The cost to the NHS in treating each outcome was calculated. 100 patients attending the oral surgery clinics, University of Wales Dental Hospital rated the effect of each outcome on their own life. The cost and effectiveness data for each outcome were entered into the decision tree and the analyses were conducted by 'folding back' the decision tree based on the probabilities. MAIN FINDINGS: Mandibular third molar retention was less costly (170 Pounds), more effective (69.5 effectiveness units on a 100 point scale) and more cost-effective (2.43 Pounds per unit of effectiveness) than removal (226 Pounds, 63.3 and 3.57 Pounds respectively). These findings were sensitive to changes in the probability of pericoronitis, periodontal disease and caries. PRINCIPAL CONCLUSIONS: Mandibular third molar retention is less costly to the NHS, more effective for the patient and more cost-effective to both parties than removal. However, should the likelihood of developing pericoronitis, periodontal disease and caries increase substantially then removal becomes the more cost-effective strategy.

A framework for the evaluation of continuing education short courses in dentistry.
The objective of this paper is to propose an evaluation framework for short courses in continuing education for general dental practitioners (GDPs) (so called, Section 63 courses). Existing monitoring and evaluation procedures in the West Midlands deanery were examined and an improved evaluation framework was then devised, piloted and revised. A 5 phase method was used incorporating the examination of existing practice (Phases 1 and 2), development of a new framework (Phase 3), piloting (Phase 4) and revision of the evaluation framework in the light of the pilot. This approach will be implemented in the West Midlands and may be adapted for national use (Phase 5). It was found that existing monitoring and evaluation was inconsistent in prevalence and scope. Those involved in short courses were in favour of a more consistent and visible evaluation, including some assessment of impact-on-practice and cost-effectiveness. In conclusion, meaningful evaluation needs to include four key processes: data gathering; data analysis; dissemination and, action planning (reviewing provision in the light of the data analysis). Thus, this evaluation framework feeds into a quality development cycle designed to ensure high quality and relevant short course provision for general dental practitioners.

Where is UK general dental practice going?
Dentistry is a fundamental part of healthcare; without it a large proportion of the population would suffer severe detriment to their general health. However, in order to achieve our professional aims we have to pursue the business of dentistry.

Personal Dental Services--a practitioner's point of view.
NHS dentistry has seen many changes recently. The latest has been the introduction of Personal Dental Services. This article describes the experiences of two general dental practitioners in their practice who entered as a first wave pilot. The article explains the steps involved in generating a proposal and preparing a practice to run as a pilot. The authors have highlighted areas of particular concern for others to consider before embarking on a similar journey.

Repeat general anaesthesia for paediatric dentistry.
AIMS: To investigate patterns of referral, disease and treatment for healthy children who had received two or more dental general anaesthetics (DGA) for exodontia. METHODS: Records from 200 episodes of repeat DGA were studied retrospectively. RESULTS: The mean age of patients at first referral was 5y4m, and the mean interval before repeat was 22 months. Self-referrals rose from 14% at DGA1 to 30% at DGA2. New caries at second referral, where all diagnosed disease had been treated at DGA1, accounted for only 15% of the total. Where a specific request was made in the referral, only 8% of letters matched the charting made in hospital. 30% of all specific requests were honoured, but then required treatment for previously diagnosed caries at DGA2.75% of single-tooth extractions required repeat DGA for caries left at DGA1. CONCLUSIONS: It may be too optimistic to address only the most grossly diseased teeth when a child requires GA exodontia. A more radical treatment-planning approach, combining primary care, secondary care and public health considerations, may be required to avoid the unnecessary use of DGA.

A study of prophylactic antibiotic prescribing in National Health Service general dental practice in England.
OBJECTIVE: To study the use of prophylactic antibiotics by general dental practitioners. DESIGN: A postal questionnaire of National Health Service (NHS) general dental practitioners in ten English Health Authorities. SUBJECTS: General dental practitioners (GDPs) (1544) contracted to provide NHS treatment in the Health Authorities of Liverpool, Wirral, Oxfordshire, Buckinghamshire, Nottingham, North Nottinghamshire, Sheffield, Newcastle, Northumberland and North Tyneside. MAIN OUTCOME MEASURES: The questionnaires were analysed and the responses to each question expressed as absolute frequencies. RESULTS: Responses to the questionnaires were received from 929 (60.1%) practitioners. Over 40% of general dental practitioners would prescribe prophylactic antibiotics for patients with no relevant medical history for minor oral surgery to prevent postoperative infection. Amoxicillin was the predominant choice of antibiotic in this situation. Between 15-67% of GDPs failed to prescribe prophylactic antibiotics for at risk medically compromised patients. GDPs also prescribed for patients with a medical history not known to be at risk from dental procedures. Over 50% of GDPs however, would seek specialist advice about prophylaxis if they were unsure of the indications and over 90% of GDPs indicated they would use the current recommended regime for antibiotic prophylaxis for patients at risk of infective endocarditis. CONCLUSIONS: The evidence from this study suggests that a significant number of the practitioners surveyed prescribe prophylactic antibiotics inappropriately, both for surgical procedures and for patients at risk from endocarditis. There is also evidence that practitioners prescribe antibiotic prophylaxis for clinical procedures and medical conditions for which there is little evidence. The results suggest that there is a need for the development of guidelines for practitioners on the appropriate prophylactic use of antibiotics.

The ability to successfully include primary dental care practitioners in commissioning groups.
OBJECTIVES: To evaluate two total purchasing (TP) sites and ascertain whether general dental practitioners (GDPs) could be successfully included in the total purchasing model of health care commissioning. Another objective was to examine the role GDPs may play in future primary care commissioning groups and trusts. DESIGN: An observational cross-sectional study of two dental purchasing pilots in the North West Region. SUBJECTS: Two TP sites were studied, one in South Cheshire, the other East Lancashire. Each TP organisation had a dental subgroup which had a formal structure and was given an active role in dental healthcare service decision making. MAIN OUTCOME MEASURES: General dental practitioners' ability to manage dental health care provision in the selected sites and the suitability and effectiveness of the services managed by them. RESULTS: GDPs were willing and able to form cohesive primary care commissioning organisations but attitudes in secondary care prevented the implementation of their decisions. CONCLUSIONS: Structural, organisational and psychological changes would be necessary if GDP led purchasing were to be successfully implemented. Such changes are vital if GDPs and the dental profession are to have an effective role in the newly formed primary care groups and trusts.

Evidence-based dentistry: an overview of the challenges in changing professional practice.
A great deal of effort and resources are currently being directed at developing an evidence-based approach to healthcare delivery. The success of the evidence-based movement will depend upon the provision of necessary support to help GDPs achieve change. This paper aims to give an overview of current knowledge on what types of interventions are most effective at changing health professionals' clinical practices. Barriers to change are highlighted and the implications for the development of evidence-based dentistry are considered. Further research on organisational, social and personal influences affecting the application of evidence-based practice is necessary.

Can audit improve antibiotic prescribing in general dental practice?
OBJECTIVE: To investigate whether clinical audit can improve general dental practitioners' prescribing of antibiotics. DESIGN: An intervention study carried out in general dental practice in the North West of England. METHOD: Information was collected over an initial six-week period from 175 general dental practitioners on their current antibiotic prescribing practices. The information collected was the antibiotic prescribed including dose, frequency and duration, the clinically presenting signs and conditions, the medical history (if for prophylaxis), and any other reasons for prescribing. This was compared to the practitioners' antibiotic prescribing for a further six-week period following an audit, which included an educational component and the issuing of guidelines. RESULTS: During the initial period practitioners issued 2316 prescriptions for antibiotics. This was reduced by 42.5% to 1330 during the audit. The majority of the antibiotics (81%) for both periods were prescribed for therapeutic reasons. The most commonly prescribed antibiotics were amoxycillin (57.6%), metronidazole (23.8%), penicillin (9.3%), erythromycin (4.8%) and a combination of amoxycillin and metronidazole (1.7%). The antibiotic regimens used by practitioners were significantly changed by the audit (P<0.001) and there was a significant reduction in the number of prescriptions (P<0.05) which did not conform to national guidelines. CONCLUSIONS: The results from this investigation support the conclusion that clinical audit, with the issuing of guidelines and an educational component, can change prescribing practices leading to a more rational and appropriate use of antibiotics in general dental practice.

Are antibiotics being used appropriately for emergency dental treatment?
AIM: To investigate the therapeutic prescribing of antibiotics to patients presenting for emergency dental treatment. DESIGN: A prospective clinical study. METHOD: Information was collected via a questionnaire concerning the patient's reason for attendance and treatment undertaken at emergency dental clinics in North and South Cheshire. RESULTS: Over an 11-week period 1,069 patients attended the five clinics, 1,011 questionnaires were analyzed. The majority of the attendees had pain (879/1011). 35% (311/879) of these patient had pulpitis and 74% (230/311) had been issued a prescription for antibiotics, without any active surgical intervention. Th principal antibiotic prescribed for both adult and child patients was amoxicillin. CONCLUSION: The majority of patients attending the emergency dental clinics had pain, with a large proportion having localised infections either as pulpitis or localised dental abscess. Three quarters of these patients had no surgical intervention and were inappropriately prescribed antibiotics.

Changing patterns and the need for quality.
This series of articles is aimed at anybody who places crowns and other extra-coronal restorations (ie veneers and shims) on individual teeth. We hope that everyone from experienced practitioners to undergraduate students may find something of value. Whoever reads them, we would ask to do so with an open mind. We have tried not to be dogmatic, and the techniques and materials described are not the only ones available, but are the ones which accord with the principles we describe.

A survey of antibiotic prescribing by maxillofacial consultants for dental extractions following radiotherapy to the oral cavity.
OBJECTIVES: To analyse the antibiotic prescribing trends for exodontia and minor oral surgery in patients with a history of radiotherapy. Also, to evaluate the use of hyperbaric oxygen as a separate modality in the prevention of osteoradionecrosis. DESIGN: A survey of antibiotic prescribing involving the analysis of a questionnaire which included the management of three patients with a history of head and neck malignancy. METHOD: The heads of the departments in each unit in the UK were sent a closed-response questionnaire. Antibiotic prescribing was assessed in three case scenarios. Case one referred to a patient that had surgery alone as part of the management of head and neck cancer, who needed the surgical removal of second molar roots. Case two referred to a patient that had surgery and adjuvant radiotherapy as part of the management of head and neck cancer, and needed the same procedure as in case one. Case three included a patient with a history of surgery and adjuvant radiotherapy, who required the extraction of three mobile and periodontally-involved lower incisors. Consultants were also asked about the use of hyperbaric oxygen in the patients who had radiotherapy as part of their treatment strategy. RESULTS: A total of 109 questionnaires were sent to all the Maxillofacial Units in the UK. The response rate was 73%. In patients with a history of radical surgery alone for the management of head and neck cancer, 20% of the surgeons advocated pre-operative antibiotics for the surgical removal of lower posterior teeth. In contrast, in the patient with a history of adjuvant radiotherapy 86% supported pre-operative antimicrobial use for the surgical removal of the same teeth. In the extraction of mobile and periodontally involved lower incisors in the previously irradiated patient, 63% of the clinicians supported pre-extraction antibiotics. Postoperative antibiotics were advocated in 52% in the first case, 89% in the second case and 71% in the third case. 34% of the clinicians advocated hyperbaric oxygen for surgical removal of posterior teeth and 15% for the extraction of mobile anterior teeth. CONCLUSIONS: The use of peri-extraction antibiotics was favoured among oral and maxillofacial surgeons. There was little enthusiasm towards the use of hyperbaric oxygen as a prophylactic measure, alone or in conjunction with an antimicrobial regime. Control randomised trials that will measure the effectiveness of hyperbaric oxygen and the appropriate use of antibiotics for prophylaxis in pre- and post-operative regimes are necessary to evaluate the use of these modalities.
