title: Incidence of dentoalveolar injuries in hospital emergency room patients.
abstract: A retrospective survey over one year of a hospital emergency room population, seen at an oral and maxillofacial surgery clinic, found 271 patients (4.6% of the total population) with dentoalveolar injuries. A very large number of injuries occurred to children between the ages of 0 and 5 years (42.1%), and there was a significant number of injured patients in the adult population (19.1%). The ratio of male to female was 1.9:1. The leading cause of injury was falls (59.8%). The largest number of injuries was seen during summer. The diagnoses were lateral luxation (27.3%), concussion (17.3%), exarticulation (14.3%), tooth fracture (12.5%), intrusive luxation (11.1%), fracture of alveolar process (7.4%), extrusive luxation (3.7%), and cases with more than one diagnosis (6.3%). Most of the involved teeth were maxillary central incisors, in both dentitions.
