Surgical reconstruction of invasive external cervical root resorption with perforation and associated periodontal defect using novel bioceramic materials and cone beam computed tomography as a diagnostic adjunct- A case report.

Tooth resorption; both internal and external, occasionally occurs as an inflammatory response of the dentoalveolar apparatus to infection. Depending on the type of resorption, etiology, and the stage at which root resorption defect is detected, different treatment regimens have been proposed. This case report demonstrates the management of extensive inflammatory combined internal and external root resorption by nonsurgical endodontic therapy using a Bioceramic sealer (BioRoot RCS) and surgical reconstruction of resorptive defect using Biodentine. On follow-up at 1, 3, 6, and 12 months, clinical and radiographic evidence revealed signs of periapical healing, arrested root resorption, and periodontal reattachment. The inclusion of cone beam computed tomography plays a crucial role in diagnosis, decision-making, and treatment planning and thus successful management of such cases having Endodontic-Periodontal involvement. As supported by clinical and radiographic findings at 12-month follow-up, treatment of cases with extensive root resorption and associated involvement of periodontium can be successfully done using bioceramic materials.
