Scope of practice, referral patterns and lesion occurrence of an oral medicine service in Australia.

AIM: The purpose of this study was to examine the scope of practice, lesion occurrence and utilisation of referral-based hospital and private practice oral medicine and oral pathology (OMP) services in Australia. MATERIALS AND METHODS: Clinical records of patients referred to a hospital (n=500) and private (nbequals;1104) OMP clinic were audited. For each patient, the following parameters were recorded: age, gender, source of referral, reason for referral, site of lesion/condition if applicable, medical and drug history, diagnostic services utilised, clinical and histopathological diagnoses rendered, medications prescribed and further treatment required. RESULTS: A majority of the referrals were generated by general dental practitioners. The most commonly seen problems were epithelial hyperplasia/hyperkeratosis, oral candidosis, oral lichen planus, xerostomia, recurrent aphthous ulcers and burning mouth syndrome. OMP specialists requested diagnostic imaging for 13% of hospital and 9.42% of private patients, diagnostic biopsies were required for 18.4% of hospital and 19.3% of private patients, blood tests were ordered for 14.4% of hospital and 12.13% of private patients, while medications were prescribed for approximately 36% of hospital and 51% of private patients. CONCLUSIONS: This study is the first to detail the scope of practice, lesion occurrence and utilisation of services offered by OMP specialists in Australia. The demand for OMP services is strong.

Analysis of workplace injuries in a dental school environment.

Workplace injuries at the University of Queensland Dental School during the period 1992-1994 were assessed to determine their incidence, and the associated indirect costs, causal factors, and appropriate preventive strategies. Overall, dental chairside assistants experienced a higher incidence of injuries than students both on a per worker and per time basis. Of the injuries with a low risk of cross-infection, burns and scalds from sterilizing equipment, and eye injuries in laboratories were the most common. This emphasizes the importance of wearing appropriate protective equipment in areas outside the treatment zone, and the need for signage and education. Common causes of sharps injuries were burs left in handpieces, two-handed needle recapping, and cleaning of probes in the sterilizing room. Changes to techniques and equipment would prevent such incidents. A range of factors which contribute to the calculation of indirect costs following injuries in the dental workplace are identified.

Australian Dental Research Fund Trebitsch Scholarship. An assessment of the permeability of dental protective gloves.

Several overseas studies have documented the presence of defects in unused latex and vinyl gloves. Since such defects compromise the barrier protection afforded by gloves, information regarding the frequency and site of defects which occur during manufacture is of direct clinical relevance. This study utilized a four-stage testing procedure to evaluate defects in 13 brands of gloves which are used commonly in dental practice in Australia. Macropores in unused gloves were a significant problem, with 10 brands containing 1 per cent or more defective gloves. In addition, variations in electrical conducitivity, signifying microporosity or inconsistencies in thickness, were also observed. These findings indicate that there is room to improve further the quality of protective gloves.
