Endodontic approach using bioceramic material in a maxillary lateral incisor with internal and external resorption.

External root resorption begins in areas where the precementum layer has been lost, resulting in exposure of the mineralized portion of the dental surface and rendering it susceptible to the action of osteo‑remodeling cells. Dental trauma is a well‑recognized etiological factor associated with several pulpal alterations, including external root resorption. This article reports on a clinical case of endodontic treatment of a maxillary lateral incisor affected by both internal and external root resorption, managed with a bioceramic material. A female patient with a history of dental trauma, pulp necrosis, and combined internal and external root resorption of a maxillary lateral incisor was treated. During the first appointment, local anesthesia was administered, followed by access cavity preparation, rubber dam isolation, irrigation with saline solution and 2% chlorhexidine gel, working length determination, canal instrumentation using Prodesign S files, drying of the canal, and placement of an intracanal medicament based on calcium hydroxide. At the second appointment, performed 15 days later, the intracanal medicament was removed, and the root canal system was obturated using the bioceramic sealer Bio‑C Sealer in combination with a thermoplastic obturation technique. Follow‑up evaluations were conducted over a three‑year period, assessing both radiographic regression of the resorptive process and the presence of clinical symptoms. Based on this case report, it can be concluded that remission of the pathological process, arrest of root resorption, and preservation of both function and esthetics of the affected tooth are achievable with the use of bioceramic materials. This therapeutic approach may therefore represent a viable alternative to tooth extraction, contributing to the long‑term maintenance of the dental element.
