Resumo (EN)

Objective – The aim of the study was to: I) evaluate the prevalence of traumatic dental injuries (TDIs) in pre-scholars; II) compare the prevalence of the TDIs in private and public schools; III) evaluate the need of treatment of the TDIs. Methods – This study was conducted with the use of a transversal epidemiological study in 411 preschool children. Results – TDIs were classified according to Ellis (1972), adding color alteration to this criterion. Data were submitted to Poisson regression analysis. TDIs prevalence was 14.8%. The superior central incisor was the most affected tooth, without any difference between left and right sides. Univariate analysis showed that girls presented less trauma than boys and the prevalence was lower in public schools (p < 0.037). The most common trauma in public schools were fractures of crowns involving only enamel while in private schools was alteration in the color of the crown and TDIs needed treatment. Conclusion – It was concluded that there was association among traumatic dental injuries and gender (boys had more trauma than girls), school (children from private school had more TDIs) and big need of treatment for the LDTs exists.
