Conservative Treatment of Invasive Cervical Resorption Using Mineral Trioxide Aggregate (MTA) and Fiber-Reinforced Composite: A Case Report

Invasive cervical resorption (ICR) is not only a rare but also an aggressive dental condition that can further progress, leading to significant structural damage and tooth loss if not diagnosed and managed early. The following case report delves into the successful conservative treatment of a maxillary lateral incisor affected by ICR in a 33-year-old man with a history of dental trauma. Routine clinical and radiographic evaluation, along with cone-beam computed tomography (CBCT), confirmed Heithersay class III resorption with subcrestal involvement. The treatment involved root canal therapy, surgical debridement, and defect restoration with mineral trioxide aggregate (MTA), followed by Ribbond fiber-reinforced (Ribbond, Inc., Seattle, WA) composite for structural reinforcement. A follow-up of six months postoperatively showed no recurrence of resorption, and the patient remained asymptomatic, demonstrating the effectiveness of a multidisciplinary approach. This case highlights the importance of CBCT-guided diagnosis, biocompatible materials, and minimally invasive techniques in the management of invasive cervical resorption.
