CLINICAL AND TOMOGRAPHIC FOLLOW-UP OF AN EXTERNAL ROOT RESORPTION IN A MAXILLARY CANINE: CASE REPORT CLINICAL CASE

Abstract

External root resorption is a pathological process, in which there is cementum, dentin and bone tissue degradation, that can occur in teeth with endodontically treated or vital teeth. External root resorption occurs by several factors, such as trauma, impacted third molars, excessive forces, occlusion, orthodontic treatment, and chemical irritation. Root resorption can occur in the cervical, middle, and apical thirds. External cervical resorption frequently occurs after or during orthodontic treatments, especially in maxillary canines. External cervical resorption (ECR) is characterized by a slow and asymptomatic process. The purpose of this clinical case report is to present the follow-up of a maxillary canine (23) with external root resorption. In this follow-up, imaging exams from 2016 and 2020 are presented, and it was possible to observe that the resorption process was stabilized and presenting signs of repair. Clinical examination, detailed anamnesis and periapical radiographs are fundamental to determine the pathology. Treatment planning is different for each case, depending on clinical and radiographic factors, causes and moment of resorption discovery, whether the structure of the remaining tooth is restorable and whether there is pulp involvement. In some case, by removing the pathogenic agent, resorption can be stopped, and mineralized tissue can be formed.
