XAVIER, Cristina Braga et al. Study of dentoalveolar trauma in patients treated at an Oral and Maxillofacial Surgery. RGO, Rev. gaúch. odontol. (Online) []. 2011, 59, 4, pp. 565-570. ISSN 1981-8637.

Objetive The present study aimed to evaluate the epidemiological profile of patients with traumatic dental injuries in permanent teeth, as well as to identify the type of trauma, the teeth most affected and the most frequent causes of dentoalveolar trauma. Methods The sample comprised all of the dental records of patients treated at the Oral and Maxillofacial Surgery Department at the Faculty of Dentistry at the Federal University of Pelotas, in the Brazilian state of Rio Grande do Sul, over a five-year period, totaling 308 cases and 793 teeth with traumatic injury. The data were evaluated statistically. Results The results obtained demonstrated that the most prevalent age group was 13-19 (32.7%); males were affected in 74.6% of injuries; the most common etiology was cycling accidents (23.3%); the most frequent types of trauma were avulsion (17.2%) and non-complicated crown fracture (17.2%); and the most affected teeth were the maxillary central incisors (66.7%). Conclusion It was concluded that the distribution of trauma injuries, in this paper, is very similar to that presented in most of the published studies. However, with regard to the etiology variable, some local/regional characteristics were found, reinforcing the importance of epidemiological studies for the development of preventive and therapeutic methods specific to the health service.
