Resumo
Objective: The aim of this study was to evaluate the epidemiological aspects and clinical factors associated
with avulsion of permanent teeth. Materials and Methods: The sample consisted of 261 avulsed teeth of
170 patients seen in the Dental School of the Federal University of Goiás, Brazil, from 2000 to 2008. Result: The
highest incidence was found among boys (71.18%) aged 6-15 years (61.18%). The main etiologic factors were
falls (51.76%) and traffic accidents (29.41%). Most cases occurred in autumn (March to June; 31.18%) and
winter (June to September; 27.65%). Most avulsed teeth were the maxillary central incisor (62.45%), followed
by the maxillary lateral incisor (21.46%). A high proportion (67.23%) of injured teeth had a completely formed
root apex. Replantation was used to treat 119 teeth (45.59%) in 86 patients. Most replantations were delayed
(89.08%). Thirty-eight teeth (31.93%) were stored in dry media. Periodontal healing was found in 41 teeth
(34.45%), inflammatory root resorption, in 44 (36.97%) and replacement root resorption, in 22 (18.49%). The
most frequent treatments for replanted teeth were endodontic treatment and temporary filling of the root
canal with calcium hydroxide (58.92%) and endodontic treatment and definitive root canal filling (26.89%).
Conclusion: The epidemiological and clinical aspects of tooth avulsion in this study were similar to those
reported in other studies. The number of replantation was low, the number of teeth stored in non-physiological
conditions was high, and replantation was often delayed.
