Abstract

Root resorption is a recognized complication of orthodontic treatment, particularly in teeth with previous trauma, posing diagnostic and therapeutic challenges. This case report describes an 18-year-old male who presented with an Ellis Class II fracture on tooth #21 following completion of a two-year orthodontic treatment. The patient had a history of dental trauma ten years earlier. Radiographic and cone beam computed tomography (CBCT) evaluations demonstrated apical root resorption affecting teeth #11, #21, and #12, with partial canal calcification in tooth #11. Endodontic therapy was performed on tooth #11 using advanced techniques for negotiating the calcified canal and biocompatible materials for obturation. The fractured tooth #21 was restored successfully with a layered direct composite resin restoration, emphasizing esthetics and function. Follow-up revealed satisfactory restorative outcomes. This case underscores the importance of thorough diagnostic evaluation, cautious orthodontic force application, and integrated endodontic-restorative management to optimize treatment outcomes in patients with complex dental histories. It highlights the need for regular follow-up and multidisciplinary care to identify and manage root resorption and trauma sequelae effectively in orthodontic patients
