Aim: Determine the prevalence of dental injuries (TDI) in primary teeth and the influence of predisposing clinical factors on their occurrence and analyze the prevalence of developmental sequelae in permanent teeth and determine the association between these sequelae and age, gender, injury type, injury recurrence and sequelae in primary teeth, in children under 7 years old who sought treatment at a private pediatric dental clinic in Goiânia, Goiás, over a period of 15 years. Methodology: A retrospective study which analyzed 2725 dental records. Three hundred and eight dental records with 412 traumatized primary teeth were selected. This constituted the sample used to determine the prevalence of injuries in primary teeth and their association with predisposing clinical factors (Article 1); of these, 241 primary teeth (148 dental records) were followed up until the eruption of the permanent successor teeth. This was the sample for the study of sequelae in primary and permanent teeth (Article 2). All the data were statistically analyzed using the frequency distribution, chi-square test and logistic regression analysis. The level of significance was 5%. Results: The prevalence of dental injuries was 11.3%, with the greatest frequency in the 13-36 month age group. There was no statistical difference between genders. The most frequently affected teeth were the maxillary central incisors (83.3%). The main location of inuries was the home (43.5%), with falls the most frequent cause. The prevalence of dental TDI was similar in all months of the year. The most common type of TDI was subluxation (35.1%). Clinical factors overjet > 3 mm and negative overbite showed a significant difference between the trauma and no-trauma groups. In 46.5% of the cases, treatment was sought in the first 24 hours after the trauma. The most prevalent type of treatment was follow-up (51.0%). Color alteration of crown (26.0%) was the most frequent sequelae for primary teeth. The sequelae found in permanent teeth were enamel discoloration and/or hypoplasia (74.1%) and eruption disorder (25.9%). No significant relation was found between sequelae in permanent teeth and sequelae in primary teeth, type of trauma, gender or TDI recurrence. The only statistical difference was found in relation to the child s age at the moment of trauma. Conclusion: Immediate treatment of the child with a TDI, associated with the efficient diagnosis and long-term follow-up are decisive for the success of treatment. New research to help establish an effective protocol for the treatment of TDIs in primary teeth and the implementation of strategies that prepare professionals to treat TDIs and to educate the public about prevention and treatment of these lesions is necessary..
