Abstract:
Tooth resorption is the degradation of dental hard tissue due to the continuous action of odontoclasts. External cervical resorption refers to the cervical resorption of a tooth due to destruction and/or defects of the periodontal ligament or subepithelial cementum. In this paper, we report a case of maxillary central incisor with external cervical resorption after dental trauma and orthodontic treatment. The resorption site and morphology of the affected tooth were thoroughly analyzed by cone beam computed tomography prior to the operation. Dental operating microscope and layered external repair with composite resin and bioceramics ensured a perfect restoration of the resorption, and the vital pulp was preserved. The 6-year follow-up indicated a favorable treatment effect.
