Background: Anterior teeth are particularly vulnerable to traumatic injuries during physical activities, which can significantly affect the pulp and periapical tissues. This case report aims to present a strategy for managing combined traumatic lateral and extrusive luxation in an immature permanent tooth.Case Presentation: A 10-year-old male patient presented to the Pediatric Dentistry Department at the Hamadan School of Dentistry with an anterior tooth injury that had occurred less than 24 hours earlier, resulting in lateral luxation and extrusion of the upper left permanent central incisor. Following radiographic assessment, the luxated tooth was repositioned under local anesthesia and splinted to two adjacent teeth on each side. At the two-week follow-up, the repositioned tooth exhibited signs and symptoms of pulpal necrosis. Complete pulp extirpation was performed, followed by the placement of a calcium hydroxide dressing. One week later, an apexification procedure was performed using a mineral trioxide aggregate (MTA) apical plug to establish an adequate apical seal and create an artificial apical stop for the obturation material. Radiographic evaluations at six and twelve months confirmed successful periapical healing.Discussion: The promising short-term outcomes of this case report demonstrate the effectiveness of repositioning, splinting, and MTA apexification in managing necrotic immature teeth resulting from combined traumatic injuries.
