The prevalence of root caries in Australia is expected to increase due to an ageing population and increase in tooth retention. This report presents findings from the Australian National Study of Adult Oral Health 2017-18.
A stratified random sample of 15 731 Australians aged ≥15 years participated in a telephone or online survey. Of those, 5022 dentate people underwent an oral assessment. Carious root surfaces were defined as ≥1 mm of affected dentine/cementum. Prevalence was defined as the percentage with ≥one natural tooth with untreated caries on root surfaces. Severity was measured as the mean number of root surfaces with caries.
Prevalence of untreated root caries in the Australian adult dentate population was 8.2% and increased with increasing age (range 2%-17.8%). Men (9.3%) compared to women (7.2%), people living in remote (18.0%) versus regional (9.3%) and major cities (7.6%), and those with the lowest household income (15.4%) compared to middle (7.6%) and highest tertile (3.2%) had untreated root caries. The average number of decayed or filled root surfaces in the Australian adult population was 1.1 (95% CI 0.9, 1.2).
Root caries was associated with older age, living outside a major city and lower income.
由于人口老龄化和牙齿保留率的增加，澳大利亚根面龋的患病率预计将会增加。本报告介绍了 2017-18 年澳大利亚国家成人口腔健康研究的结果。
在这项分层随机抽样调查中，共有 15731 名年龄在 15 岁及以上的澳大利亚人参与了电话或在线调查。其中，5022 名有牙者接受了口腔评估。有龋根面被定义为受影响牙本质/牙骨质≥1mm。患病率定义为每颗有未经治疗的根面龋的天然牙的百分比。严重程度用有龋根面的平均数量来衡量。
澳大利亚有牙成年人的根面龋未治疗患病率为 8.2%，并随年龄增长而增加（范围为 2%-17.8%）。与女性（7.2%）相比，男性（9.3%）、生活在偏远地区（18.0%）和地区（9.3%）和主要城市（7.6%）的人群以及收入最低的家庭（15.4%）比中等收入（7.6%）和最高收入（3.2%）的人群更易发生未经治疗的根面龋。澳大利亚成年人的平均患龋或充填根面数为 1.1（95%CI 0.9,1.2）。
根面龋与年龄较大、居住在主要城市以外和收入较低有关。
