To report the experience of coronal dental caries in the Australian adult population.
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.
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.
Socioeconomic inequalities in caries experience persist in Australia.
报告澳大利亚成年人群体中冠状龋齿的发病情况。
对 15 岁及以上的有牙人群进行在线或电话访谈和口腔检查（n=5022）。记录龋齿、缺失和填补的牙面数（DMFS）。自变量为人口统计学、社会经济状况和口腔保健特征。计算 DMFS>0 的比例、平均 DMFS 及其组成部分。
总体而言，32.1%的人有龋齿，男性（34.7%）的比例更高，居住在偏远地区的人比居住在主要城市和地区的人高 40%。龋齿的患病率从最低收入组的 37.4%到最高收入组的 25.0%不等。最低收入组的平均龋齿数是最高收入组的三倍。未参保人群的龋齿患病率较高，补牙牙面均值较低。就诊模式不理想的参与者的龋齿患病率比对照组高两倍。总体而言，四分之三（77.4%）的人在恒牙中有至少一个补牙。这一比例从 15-34 岁人群中的 61.6%上升到 55-74 岁人群中的 88.0%。
澳大利亚的龋齿发病情况存在社会经济不平等现象。
