Self-revascularization Following Horizontal Root Fracture with Lateral Luxation Injury in a Permanent Maxillary Central Incisor

Abstract

Repair or regeneration of the pulp, following trauma, is a part of the wound healing process. However, pulp necrosis or root resorption, whether partial or complete, might obstruct this process. Because of the neurovascular bundle at the apical foramen and the periodontal ligament, the pulp in this fragment generally remains normal when the apical fragment is not moved. We describe a mature upper left central incisor with a horizontal root fracture in the mid-third of the root and lateral luxation that healed on its own after undergoing a procedure called self-revascularization. The fracture was detected during a routine dental checkup on a tooth that was asymptomatic. Two tooth pieces with trabecular bone between them were discovered using periapical radiography and cone-beam computed tomography (CBCT). Therefore, the endodontic intervention was not needed. Regular follow-up after trauma is mandatory to evaluate any signs of pulp necrosis. CBCT can help assess healing and identify resorption.
