In permanent teeth, external root resorption is a pathological process that can present different causes, associated to it or not. The correct diagnosis of the cause is important to define the best treatment plan that can involve different techniques, characterizing a multidisciplinarity. The present study had the objective of reporting a case of external root resorption in the cervical region of 12. After clinical, radiographic and tomographic examination, the presence of a resorption compatible image involving the cervical third with limits close to the alveolar bone crest . There was also communication with the pulp cavity. Although pulpal vitality was present, the treatment plan involved endodontic treatment followed by orthodontic extrusion for recovery of the biological distance and restoration with acid attack system and composite resin. The endodontic treatment consisted of biomechanics, calcium hydroxide use for 14 days and finished with obturation with cones of gutta percha and cement of calcium hydroxide. Orthodontic extrusion was completed after 4mm of tooth structure was moved when a minor surgery was performed to expose the lesion. With the exposure of the reabsorbed area, it was possible to perform the restoration of the cavity with acid attack system and composite resin. After 18 months, clinical control demonstrated root surface integrity and normal mobility of the treated tooth
