The present study aimed at assessing potential sequelae on root length and buccal as well as palatal bone plates of canines and adjacent teeth after unerupted canines were subject to orthodontic traction. To this end, cone-beam computed tomography was used. A total of 16 patients were assessed. They presented with upper canine impacted on one side, treated by means of crown perforation and closed surgical exposure. Upper canines not subject to traction and contralateral adjacent teeth served as control. Cone-beam computed tomography was taken with a view to assessing root length and buccal/palatal alveolar bone attachment. No statistically significant differences were found for canine root length and adjacent teeth when the study groups were compared. Likewise, no statistically significant differences were found for buccal/palatal alveolar bone attachment of lateral incisors, canines and first premolars when the study groups were compared. Treating impacted canines by means of closed surgical exposure associated with canine crown perforation produces minor effects on root length and buccal/palatal alveolar bone attachment, thereby demonstrating this treatment protocol to have good long-term prognosis.
