Abstract

The use of mineral trioxide aggregate (MTA) for complete endodontic obturation of an immature maxillary central incisor is reported. The injured tooth of a 9-year-old male was avulsed secondary to a sports-related traumatic event. Early attempts at pulpal revascularization of the replanted tooth proved unsuccessful, as evidenced by radiographic signs of external inflammatory root resorption in the middle to cervical thirds of the root. Calcium hydroxide apexification over a 1-year period promoted cessation of the resorptive process, but was unable to adequately form an apical root canal barrier. Due to the extent of external resorption and the lack of an apical stop, a novel endodontic treatment using mineral trioxide aggregate was utilized. At 865 days post-injury, the tooth remained asymptomatic with clinical and radiographic evidence of periodontal health.
