pulp revascularization following severe extrusive luxation injury in mature permanent mandibular incisors: a case report

Introduction: pulp necrosis is a common consequence of extrusive luxation in mature teeth with complete apical closure. in this report, the researchers presented a case with severely extruded mature mandibular incisors (more than 5 mm), which did not lead to pulp necrosis. case presentation: the case was a nine-year-old female with severe dentoalveolar trauma to the anterior maxillary and mandibular region, as a result of a bicycle accident. the treatment consisted of mandibular alveolar bone and central incisors repositioning. after 18 months of follow-up, no sign of pulp necrosis was observed. conclusions: in young patients with severe extrusive luxation and closed apices, there is the potential for pulp survival, and early endodontic treatment should be avoided until signs of pulp necrosis is observed.
