OBJECTIVE: Traumatic dental injury (TDI) is the world's fifth most common injury affecting children and adolescents. This study aimed to predict TDI based on ear problems and other factors among Australian children aged 4 years or over.
METHODS: We used two longitudinal studies: the Longitudinal Study of Indigenous Children (LSIC) and the Longitudinal Study of Australian Children (LSAC). The outcome was the prevalence of TDI in children aged 14 years. We assessed 50 features, including demographic characteristics, health conditions (such as ear diseases) and health-related behaviours of the children, their parents, and other family members in children aged 4-6 years. The performance of machine learning algorithms was evaluated using the area under the receiver operating characteristic curve (AUC) with its 95% confidence interval, along with sensitivity (recall), specificity, precision (positive predictive value), F1 score (the harmonic mean of sensitivity and precision) and accuracy (the proportion of correct predictions). These metrics were evaluated for the full sample and separately for Indigenous and non-Indigenous subgroups, using both the full sample and stratified models. A sensitivity analysis was performed to compare model performance across the groups.
RESULTS: This study included 1746 Indigenous and 8357 non-Indigenous children and their parents and family members. The prevalence of TDI among Australian children at age 14 was approximately 13%. The full sample model applied to the full sample and the non-Indigenous subpopulation demonstrated high predictive performance, with AUCs of 0.85 (95% CI: 0.82-0.88) and 0.86 (95% CI: 0.82-0.89), respectively. In contrast, the model applied to the Indigenous subpopulation demonstrated lower performance, with AUC values ranging from 0.76 (95% CI: 0.68-0.83) in the full sample model to 0.80 (95% CI: 0.70-0.83) in the stratified model.
CONCLUSIONS: Our findings indicated that early childhood ear problems were strong predictors of traumatic dental injuries in Australian children.
