CBCT-guided Surgical Management of Patel Class 2Bp External Cervical Resorption Using Biodentine: A Case Report.

External cervical resorption (ECR) is an aggressive kind of root resorption that poses significant diagnostic and treatment challenges. In this instance, a 58-year-old woman with a history of dental trauma and prior endodontic access preparation presented with minor discomfort and swelling affecting her upper front teeth. A Heithersay Class II and Patel Class 2Bp resorptive lesion in her maxillary left central incisor was precisely identified using CBCT imaging. Since the root canal could not access the lesion, surgical exposure was carried out, followed by complete debridement and Biodentine restoration of the defect along with root canal therapy. In order to guarantee appropriate repair stabilisation prior to final obturation and restoration, root canal therapy was finished utilising a two-visit regimen. A positive clinical outcome was achieved by using CBCT for diagnosis, surgical management for total removal of resorptive tissue, and Biodentine as the healing material. The importance of precise diagnosis, thorough planning, and suitable restoration for effective ECR management is highlighted by this instance.
