The objective is to evaluate the frequency of trauma in primary teeth, the sequelae resulting from injuries involving the supporting tissues, as well as the association of these injuries with clinical and radiographic sequelae. This was a longitudinal clinical study, in which 342 traumatized teeth, assisted at the dental service of a public institution, were evaluated after the trauma and after 24 months. The data were submitted to a descriptive analysis and the Chi-square test (p≤0.05). The highest frequency of trauma occurred at age 24-35 months, the main etiological factor being the decrease of height (77.8%), male gender (59.5%), dental arch (96.5%), tooth 51 (43.1%); 70.6% had more than one affected tooth and 8.2% had a history of trauma; the most prevalent injury was lateral luxation (33.6%). In the proservation, there was an association between type of injury to the supporting tissue with the presence of radiographic sequelae (p = 0.02) and early loss (p = 0.01). In conclusion, the main sequelae observed were tooth crown discoloration and inflammatory root resorption and there was a significant association between the type of support tissue injury and the presence of radiographic sequelae and the early loss of the traumatized deciduous tooth.
