Abstract

Aims: To report the experience of coronal dental caries in the Australian adult population. Methods: Dentate people aged 15 years and over were online or telephone interviewed, and dental examined (n = 5022). The number of decay, missing and filled surfaces (DMFS) were recorded. Independent variables were demographic, socioeconomic conditions and dental care characteristics. Proportions of DMFS >0, average DMFS and its components were calculated. Results: Overall, 32.1% had decayed surfaces, with a higher proportion found in males (34.7%) and 40% higher in those living in remote areas than in those living in major city and regional areas. The prevalence of decayed surfaces varied from 37.4% (lowest income group) to 25.0% (highest income group). The mean number of decayed surfaces was three times higher in the lowest income group compared to the highest one. Uninsured people had a higher prevalence of decayed surfaces and lower mean of filling surfaces than insured group. Participants with an unfavourable pattern of dental visiting had two times higher prevalence of decay than their counterparts. Overall, three quarters (77.4%) had at least one filling in their permanent dentition. This percentage increased from 61.6% among 15–34 year olds, to 88.0% among those aged 55–74 years. Conclusion: Socioeconomic inequalities in caries experience persist in Australia.
