Abstract

The aim of this study was to verify the survey of causes of maxillofacial and dental traumatisms in patients assisted at the Department of Surgery and Maxillofacial Oral Traumatology at the First-Aid Municipal Clinic of a city from São Paulo State with 600.000 residents, in the period from January 1998 to April 2002. 756 cases were selected and data regarding sex, date of birth (age), service date, causes of trauma, involved areas, dental involvement and type of dental trauma were noted in a chart. The results showed that: 80,29% of the traumatisms occurred in males; the age group more involved was 25-29 anos (51,87%); the most frequent cause was automobilist/bicycle accidents (25,33%); the area of the nasal bones was the more involved representing 32% of the cases; the anterior permanent teeth the most affected (69,39%) and the type of dental trauma more frequent was the avulsion (35,37%). It was verified by the qui-square test of adherence to an uniform distribution that there was statistical difference in all the 6 analyzed items (p < 0,05). It was concluded that the occurrence of maxillofacial traumatism was more frequent in male adults patients, related to automobilist/bicycle accidents, being the area of the nasal bones the most affected, the anterior permanent teeth the most involved and the avulsion the most frequent dental trauma. UNITERMS: dental traumatisms; mandibular traumatisms; maxillofacial traumatisms
