Background: Increase in life expectancy and tooth retention in contemporary Australian adults may increase population-level burden of having root caries. This study aimed to describe patterns and evaluate associations of root caries with socio-demographic, socio-economic, clinical and behavioural factors. Methods: A secondary analysis was undertaken using data from the National Survey of Adult Oral Health 2004-2006, which included 5505 randomly general adults 15+ years old. Participants underwent an oral examination and completed an interview and a questionnaire. Prevalence and mean number of decayed/ filled root (root DFS), untreated root (root DS), filled root (root FS), gingival recession, oral hygiene and gingival status were derived from examinations. Socio-demographic, socio-economic and behavioural factors were self-reported. Multivariable models were generated to estimate prevalence ratios (PR), mean ratios (MR) and confidence intervals (95% CI), adjusting for number of surfaces with gingival recession. Additional analysis for older adults 60+ years old was presented. Results: The prevalence of root caries was 25.3% (CI= 23.6-27.1) and 62.0% [CI= 58.7-65.1] among general and older adults, respectively. Risk factors found were similar in both populations. Smokers had higher prevalence and mean number of root DFS, DS and FS than never-smokers. In contrast with poor oral hygiene, high income and frequent brushing were significantly associated with lower mean root DS. Frequent dental visiting was associated with higher root FS and DFS. Conclusions: Root caries affected about a quarter of Australian general adults and more than a half of older adults. People who were smokers presented a significantly higher prevalence and severity of root caries.
