title: External root resorption of the maxillary permanent incisors caused by ectopically erupting canines.
abstract: In this study, we analyzed the root resorption of 10 maxillary permanent incisors (two central and eight lateral incisors) in seven cases associated with ectopic eruption of adjacent canines. Two incisors were extracted because of marked root resorption. Two erupted after traction, whereas, five erupted after surgical exposure or without any treatment, although one lateral incisor submerged due to ankylosis. This suggests that self-correction of the ectopic canine occurs in some cases.
