Dental services provided by dentists in Australia

OBJECTIVES: To examine the efect of age and gender on dental services provided by dentists in Australia, and compare with previous estimates across the period 1983-1984 to 2013-2014. METHODS: Data were collected by mailed survey from a random sample of Australian dentists. Private sector dentists were the focus of the analysis. Data were weighted to the age and sex distribution of Australian practising dentists. RESULTS: The analysis was based on service logs collected from n = 211 dentists. Adjusted results (rate ratio, 95% CI) showed male dentists had higher endodontic rates (1.7, 1.0-2.9) than female dentists. Dentists aged 40-49 years had higher restorative rates (1.6, 1.1-2.2) but lower preventive rates (0.5, 0.3-0.9) than those aged 20-29 years. Diagnostic services were lower for dentists aged 40-49 to 60+ years (0.8, 0.6-0.9), while denture services were higher for dentists aged 40-49 (11.1, 2.5-48.5) to 60+ years (6.4, 1.2-33.3). Crowns were higher for dentists aged 40-49 (2.4, 1.0-5.6) and 50-59 years (2.9, 1.3-6.6). Diagnostic and preventive services were consistently higher across 1983-1984 to 2013-2014. CONCLUSIONS: Younger dentists provided higher rates of diagnostic and preventive services. Over a 30-year period, there was a consistent trend towards higher provision of diagnostic and preventive services.
