Perforating Internal Root Resorption Sealed with Single-Cone Technique Using Bioceramic Sealer: A Case Report

BACKGROUND Internal root resorption (IRR) is a rare dental condition characterized by the progressive resorption of dentin within the root canal, often resulting from infection, trauma, or orthodontic treatment. When IRR progresses to perforation, it creates a communication pathway with periodontal tissues, necessitating effective endodontic therapy and perforation repair. Bioceramic sealers, known for their biocompatibility and flowability, have emerged as a promising alternative to traditional materials for filling and sealing the root canal system. Although commonly used in conventional root canal treatments, their application in filling resorptive defects is novel and unexplored in existing studies. CASE REPORT In the case report presented, a perforating IRR was evaluated and treated. The diagnosis was confirmed using a combination of periapical radiographs and cone-beam computed tomography (CBCT), ensuring precise lesion identification. The treatment involved root canal debridement with ultrasonic activation of irrigants and the application of calcium hydroxide as an intracanal medicament. Bioceramic sealers were utilized for obturation instead of traditional obturation techniques, effectively sealing the resorptive defects and repairing root wall perforations. CONCLUSIONS The case report highlights the novel use of bioceramic sealers in managing perforating IRR. While these sealers are gaining recognition in conventional root canal therapy, their application in resorptive defects represents an innovative approach, underscoring the need for further randomized clinical trials to validate their clinical effectiveness.
