Endodontic and Surgical Management of Trauma-Induced Combined Internal and External Root Resorption with Periapical Cyst: A Case Report

Root resorption, involving the breakdown of hard tissues like dentin and cementum, can result from trauma and subsequent infection, potentially leading to tooth loss. This case report details the management of combined internal and external root resorption with a periapical cyst in a 32-year-old male. After trauma, the maxillary left central incisor (#21) presented with root resorption and a displaced apex. Endodontic treatment using MTA and surgical enucleation of the cyst were performed. A 12-month follow-up showed successful resolution and tissue regeneration. This case emphasizes the effectiveness of combining advanced endodontic and surgical techniques for complex resorption cases.
