We aimed to describe the prevalence of different tooth loss outcomes along with the use of dentures and implants among Australians aged 15+ years across socioeconomic and demographic groups. In addition, we performed time trend analyses of tooth loss.
Data from the National Study of Adult Oral Health 2017-18 included gender, age, residential location, household income, Socio-Economic Indexes for Areas, possession of dental insurance and pattern of dental visiting. Outcomes were complete tooth loss, inadequate dentition, average number of missing teeth, denture wearing and implants. We compared our findings with data from previous surveys carried out in 1987-88 and 2004-06.
Tooth loss decreased from 14.4% in 1987-88 to 6.4% in 2004-06, and to 4.0% in 2017-18. The proportion of people with lack of functional dentition halved from 20.6% 1987-88 to 10.2% in 2017-18; the average number of teeth lost due for any reason slightly reduced from 2004-06 (6.1) to 2017-18 (5.7). Tooth loss increased with age and was higher among socioeconomically disadvantaged, uninsured and those with unfavourable pattern of dental visiting groups than in their counterparts.
An overall improvement in tooth retention was identified over the last decades. However, socioeconomic inequalities persist.
本研究旨在描述澳大利亚不同年龄、社会经济和人口统计学群体中 15 岁以上人群的不同缺牙结局（包括义齿和种植体的使用情况）的流行情况。此外，我们还对缺牙情况进行了时间趋势分析。
2017-18 年澳大利亚国家成人口腔健康研究的数据包括性别、年龄、居住地点、家庭收入、社会经济区域指数、是否拥有牙科保险以及看牙模式。结果包括全口缺牙、牙列缺损、平均缺牙数、戴义齿和种植体。我们将这些发现与 1987-88 年和 2004-06 年进行的先前调查的数据进行了比较。
1987-88 年的缺牙率为 14.4%，2004-06 年降至 6.4%，2017-18 年降至 4.0%。1987-88 年无功能牙列的比例为 20.6%，到 2017-18 年减半至 10.2%；由于任何原因导致的平均失牙数从 2004-06 年（6.1）略有减少到 2017-18 年（5.7）。缺牙率随年龄增长而增加，在社会经济地位较低、无保险和看牙模式不佳的人群中高于其对应人群。
在过去几十年中，总体上牙齿保留情况有所改善。然而，社会经济不平等仍然存在。
