Multidisciplinary management of an external cervical resorption and cemental tear

Aim: The case report presents the management of two different pathologies, external cervical resorption (ECR) and cemental tear, in two different central incisors, owing to the same predisposing factor i.e. trauma from occlusion. Summary: A 53-year-old man was referred to the University Dental Clinic complaining of a pink spot that he noticed on his right maxillary central incisor. After thorough clinical and radiographic examination, including (FOV) cone-beam computed tomography (CBCT), revealed ECR classified as class 3Bp in tooth 11 and a probable cemental tear on tooth 21. A root canal treatment was performed on tooth 21 using a bioceramic sealer (Bioroot (TM) RCS). Subsequently, a modified papilla preservation flap was raised over the ECR lesion of tooth 11, followed by a complete rubber dam isolation, and blocking the root canal with a single gutta-percha cone. The defect was then restored with a resin modified glass ionomer cement (Geristore (R)). A simplified papilla preservation technique was then extended to treat the cemental tear on tooth 21, after which the root canal treatment for tooth 11 was completed. A 10-months follow-up examination showed a successful outcome with clinically stable gingival margins and no further evidence of ECR recurrence.
