    Abstract:
    The aim of this paper was to assess the epidemiology of traumatic dental injury (TDI) in preschool children and its relation to socioeconomic and clinical factors. This study was carried out in Santa Maria, Brazil, during National Children's Vaccination Day, and 441 children aged 12 to 59 months were included. Data about socioeconomic status were collected through a semi-structured questionnaire administered to parents. Calibrated examiners evaluated the prevalence of TDI, overjet, and lip coverage. Data were analyzed with a Poisson regression model (PR; 95% confidence intervals). The TDI prevalence was 31.7%. The maxillary central incisors were the most frequently traumatized teeth. The most common TDI was enamel fracture. No association was found between TDI prevalence and the socioeconomic status of children. After adjustments were performed, the eldest children with an overjet > 3 mm were more likely to have TDI than their counterparts. The data indicated a high prevalence of TDI. Only overjet was a strong predictor for TDI, whereas socioeconomic factors were not associated with TDI in this age group.
