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.

Background The aim of this study was to confirm whether the level of lifetime fluoridation exposure is associated with lower dental caries experience in younger adults (15-46 years). Methods Data of the cohort born between 1960 and 1990 residing outside Australia's capital cities from the 2004−2006 Australian National Survey of Adult Oral Health were analysed. Residential history questionnaires were used to determine the percentage of each person's lifetime exposure to fluoridated water (<50%/50+%). Examiners recorded decayed, missing and filled permanent teeth ( DMFT). Socio-demographic variables, periodontal risk factors, and access to dental care were included in multivariable least-squares regression models. Results In bivariate analysis, the higher level of fluoridation category had significantly lower DMFT (mean 6.01 [ SE = 0.62]) than the lower level of fluoridation group (9.14 [ SE = 0.73] p < 0.01) and lower numbers of filled teeth (4.08 [ SE = 0.43], 7.06 [ SE = 0.62], p < 0.01). In multivariate analysis, the higher number of full-time equivalent dentists per 100 000 people was associated with a lower mean number of missing teeth (regression coefficient estimate = -1.75, p = 0.03), and the higher level of water fluoridation with a lower mean DMFT (-2.45, p < 0.01) and mean number of filled teeth (-2.52, p < 0.01). Conclusions The higher level of lifetime fluoridation exposure was associated with substantially lower caries experience in younger rural adults, largely due to a lower number of filled teeth.

Objective To examine the association between children's clinical oral health status and their residential location using the latest available data (2009) and to ascertain whether poor oral health among rural children is related to being Indigenous, having less access to fluoridated water or being of lower socioeconomic status ( SES), than children from urban areas. Design Cross-sectional survey. Setting and participant Data were collected on 74 467 children aged 5-12 years attending school dental services in Australia (data were not available for Victoria or New South Wales). Main outcome measures Clinical oral health was determined by the mean number of permanent teeth with untreated caries, missing and filled permanent teeth, and the mean decayed, missing and filled permanent teeth index ( DMFT) of 8 to 12-year-old-children and the mean number deciduous teeth with untreated caries, missing and filled deciduous teeth, and the mean decayed, missing and filled deciduous teeth index (dmft) of 5-10-year-olds. Results The multivariable models that included coefficients on whether the child was Indigenous, from an area with fluoridated water and SES, were controlled for age and sex. The mean DMFT of 8-12-year-old children and the mean dmft of 5-10-year-old-children were significantly higher in rural areas compared with urban centres after accounting for Indigenous status, fluoridated water and SES. Conclusion Children's oral health was poorer in rural areas than in major city areas. [ABSTRACT FROM AUTHOR]

Objective To determine whether a different number and type of services were provided in Australian regional areas under the Australian Government-funded Chronic Disease Dental Scheme ( CDDS). Design Retrospective analysis of administrative payments data. Setting Australia. Participants Patients receiving dental services under the Medicare CDDS. Interventions The CDDS. Main outcome measures Number and type of services. Method CDDS service categories Australian Statistical Geography Standard ( ASGS) regions were collected by the Australian Department of Human Services between 2008 and 2013 and compared by Australian Bureau of Statistics ASGS estimated resident regional 2011 population, and by employed number of dentists, dental specialists and dental prosthetists from the 2011 National Health Workforce Dataset. Results Number of services provided was greatest in major cities (79.0%), followed by inner regional (15.4%), outer regional (5.2%) and remote/very remote Australia (0.4%). Number of services per head of population decreased from 1.088 in major cities to 0.16 in remote/very remote areas. Number of services provided per dental practitioner showed minimal variation between major city (1672), inner (1777) and outer regional (1627) areas, but was lower in remote/very remote areas (641). Crown and bridge, periodontic, endodontic and removable prostheses per dental practitioner were most frequently supplied in the major cities, but restorative care and oral surgery were more frequently supplied in inner and outer regional areas. Conclusion The number of CDDS services provided declined with regional remoteness. There was a marked difference in the utilisation of the scheme between major cities and remote/very remote areas in both number and type of service levels. [ABSTRACT FROM AUTHOR]

Objective To determine if clinical oral health outcomes differ between people who reside in major city, inner regional and outer regional areas of Australia. Design Data from the National Survey of Adult Oral Health 2004-06 that used a clustered stratified random sampling design with telephone interviews, standardised oral epidemiological examinations and self-complete questionnaires were used to compare the clinical oral health. Main outcome measures Decayed, missing and filled permanent teeth. Participants Australians aged 15 years or more. Data were weighted by age, sex and regional location to the Estimated Resident Population, bivariate analysis undertaken to determine confounders and multivariate analysis completed with dental caries clinical measures as dependent variables. Results Inner regional people had a significantly higher decayed, missing and filled teeth than people from major cities ( Estimate = 1.15, P < 0.01), but there was no difference between inner and regional areas. Older people had higher outcomes for decayed, missing and filled teeth (15.42, P < 0.01) and missing teeth (9.66, P < 0.01), but less decayed teeth (−0.37, P < 0.01), and people with the highest incomes had lower dental caries experience (−1.34, P < 0.01) and missing teeth (−1.42, P < 0.01). Conclusion Dental caries experience was greater in inner regional areas than in major city areas, but not outer regional areas. Dental caries experience was similar in outer regional and major city areas. [ABSTRACT FROM AUTHOR]

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., (© 2020 Australian Dental Association.)
