Abstract
Aim: To investigate the cases attended by the Trauma Project at Estácio de Sá University from 1999 to 2019. Methodology: A review of 1.876 medical records was conducted, identifying 425 avulsion cases. The variables studied were gender, avulsed teeth, age, and type of accident/exposure. Results: Regarding age, 279 (66%) patients were up to 15 years old; 104 (24%) were between 16 and 25; 20 (5%) were between 26 and 35; 13 (3%) were between 36 and 45; and 9 (2%) were over 45 years old. As for the cause of the accident or exposure, 72 (17%) were falls; 70 (16%) were traffic accidents; 69 (16%) were bicycle falls; 65 (15%) were sports accidents; 48 (11%) were other etiologies; 48 (11%) were children's play; 43 (10%) involved some type of violence, and 10 (2%) were work accidents. The most affected region was the upper labial region, with 92.8% of cases. Regarding the affected teeth, the upper left central incisors accounted for 252 occurrences (39.6%), followed by the upper right central incisors with 226 occurrences (35.5%), the upper right lateral incisors with 54 cases (7.8%), and the upper left lateral incisors with 50 cases (7.8%). Conclusion: It was concluded that most patients treated at the Trauma Project/UNESA with dental avulsion were male, aged 15 years or younger, and had suffered falls. This trauma mainly affected upper central incisors.
