Abstract
BACKGROUND: Teeth affected with enamel defects (EDs) are at an increased risk of dental caries. In spite of improving oral health status overall in Australia, Indigenous Australians still experience higher rates of dental caries than non-Indigenous Australians. This study reports on the prevalence of EDs and dental caries experience among Indigenous children in the Kimberley region of Western Australia. METHODS: Health status of all the primary teeth (ICDAS II criteria) and the presence of EDs on index teeth (modified Dental Defects of Enamel index; DDE) of young Indigenous children that participated in a 2-arm intervention trial was recorded. Generalised estimating equations were used to estimate the association between EDs and dental caries and effect estimates were presented as odds ratios and associated 95% confidence intervals. RESULTS: Person level prevalence, from 237 children (mean age 3.6 years, SD 1.7) assessed for EDs, was 58% and tooth level prevalence was 24%. Teeth affected with demarcated or diffuse defects were associated with a two-fold higher odds of having caries experience, OR 2.5, 95% CI 1.7-3.7 and OR 2.7, 95% CI 1.7-4.0, respectively. CONCLUSIONS: The presence of EDs among young Indigenous children was associated with a higher odds of caries experience among affected teeth.
