Injúrias dentárias em dentes decíduos: estudo longitudinal

Current study analyzes 139 children with a history of traumatism in deciduous teeth through sequelae and the association between gender and age. Further, 33.8% of the sample showed that the trauma started between 24 and 35 months, with 61.2% involving males. Regarding to type of dental injury and tissue, enamel fracture (28,1%) and lateral dislocation (17,3%) were the most prevalent. De-coloration of the crown (18%), inflammatory radicular reabsorption (7,9%) and peri-apical lesion (6,5%) were diagnosed in deciduous dentition. Moreover, 13,7% of permanent teeth had emerged, with 2,9% featuring enamel hypoplasia, whereas 2,2% showed a radiographic delay in eruption and 2,2% revealed abnormal position of teeth. Chi-square test demonstrated a link at the moment of trauma with dental injury (p=0,02); type of dental injury (p=0,01) and clinical sequelae in deciduous teeth (p=0,02). Results show high prevalence of sequelae diagnosed in the follow-up and thus the importance of preservation.
