Abstract: BACKGROUND: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. METHODS: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. RESULTS: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. CONCLUSIONS:An overall improvement in tooth retention was identified over the last decades. However, socioeconomic inequalities persist.
