Objective: Traumatic dental injuries (TDIs) affect the aesthetics and function of primary teeth and can causesequelae in their permanent successors. This study assessed the distribution of TDIs and sequelae in the primarydentition and the respective permanent dentition in children treated at the Dental Trauma Centre in Brazil.Material and Methods: This cross-sectional study was conducted by collecting data from 256 dental recordsover 7 years. Descriptive statistical analyses and the Fisher exact test were used (p=0.05). Results: Sixty-twopatients presented with trauma in the deciduous teeth. TDIs were observed mostly in boys (64.50%) and inthe 2 to 4-year age group (44.10%); most injuries occurred from fall from the child’s own height (40.30%) andat home (71.20%). The most common type of trauma was subluxation (22.90%). The most prevalent clinicaland radiographic sequelae were mobility (45.60%) and periapical lesion (31.80%), respectively. Regarding thepermanent dentition, the most frequent sequela was hypomineralization (33.30%). Conclusion: According tothis study, TDIs in deciduous teeth made up 29.24% of all the cases in the Dental Trauma Program. The majortype of trauma in children was subluxation, with sequelae in both dentitions. Follow-up after trauma is importantto the maintenance of primary dentition and to prevent and treat possible sequelae in the permanent dentition.KEYWORDSDeciduous dentition; Dental health; Injury; Permanent dentition; Sequelae.
