The case of a 7-year-old boy presenting with a horizontal root fracture and concomitant avulsion of the coronal segment of a permanent maxillary central incisor is described. The coronal segment was replanted and splinted. As signs of infected pulp necrosis became apparent, one-visit apexification and root canal obturation of the coronal segment were performed. Complete resolution of the lateral lesion was observed, and the apical segment remained vital. One year after the dental trauma, there was clinical and radiographic evidence for periodontal healing. The patient later underwent orthodontic treatment with successful movement of the replanted coronal segment. The reported case illustrates the capacity of healing of complex dental injuries such as root fractures with severe coronal dislocation. Appropriate endodontic management may ensure long-term retention of severely injured teeth.
