Background:
Social determinants of oral health are complex and have been described by conceptual frameworks. A widely embraced model of children's oral health was published by Fisher-Owens et al. (2007), identifying theoretical constructs influencing oral health. The current study aimed to investigate community-level constructs described in the conceptual model.
Methods:
The Longitudinal Study of Australian Children is a cross-sequential dual cohort study, with a representative sample (n = 10090) of Australian children. Generalized estimating equations were applied to model seven waves of carer-reported oral health and community measures.
Results:
In the final model, children living in Queensland had a 1.48 (CI 1.35-1.62) increased odds of dental caries over time. Children in low socio-economic status (SES) areas (OR 1.32 CI 1.20-1.44) had an increased odds of caries. The state of Queensland (OR 1.24 CI 1.05-1.46) and poor neighbourhood liveability (OR 1.17 CI 1.05-1.31) were predictors of dental injury.
Conclusion:
By modelling available community measures, this study found SES and rurality were predictors of caries over childhood. Our results highlight the difficulty of applying conceptual models to oral health. The use of qualitative studies and realist reviews should be considered to complement statistical models to provide contextualized insights into funding, policy and service delivery on children's oral health.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
