The scope of this study was to determine the prevalence of trauma in the permanent dentition of 12-year-old schoolchildren and assess associations with demographic factors such as gender and socioeconomic status and overjet and lip coverage clinical factors. A cross-section al analysis was conducted using a representative sample of 638 students. Data were gathered by means of clinical examinations and self-administered questionnaires. Descriptive analysis was performed, followed by the use of the chi-square test and Poisson logistic regression model for the determination of significant associations. The prevalence of traumatic dental injury was 34.9%. Falls constituted the main etiological factor (49.7%), and occurred in the home (48.2%). The results of the Poisson regression analysis revealed that accentuated overjet (> 5 mm) remained associated with traumatic dental injury irrespective of the other variables [PR = 1.50 (95% CI: 1.41 to 1.61); p = 0.003]. Moreover, a statistically significant association was found between accentuated overjet and dental trauma. No significant associations were found between TDI and socioeconomic status. These findings highlight the need for prevention strategies and orthodontic correction at the onset of the permanent dentition.
