Abstract

External cervical resorption (ECR) describes the loss of dental hard tissue beginning at the cervical region of the root surface as a result of odontoclastic action [1]. Studies have shown a prevalence of post traumatic injuries to permanent teeth that range from 3.9% to 58.6% [2]. Among the types of injuries, the most frequent are pulp necrosis, internal and external resorption, calcific metamorphosis, and ankylosis [3]. There are several reasons for the high incidence of maxillary canine impaction. They include crowding; a narrow maxillary arch; a Class II, division 2–incisor relationship; familial tendency; follicular disturbance of the canine; and pathology to the primary predecessors [4-6]. Ectopic eruption of canines may cause severe root resorption of adjacent teeth.
