Extrusive Luxation in a Young Permanent Tooth – Case Report

Abstract

Traumatic injuries to permanent teeth are common in children and adolescents. Luxations, such as extrusive luxation, result from impact to the supporting tissues, causing partial displacement of the tooth. Immediate repositioning followed by stabilization and follow-up is essential. Case Report: A seven-year-old boy, after a bicycle fall, presented with extrusive luxation of tooth 11. In the emergency care, no dental repositioning was performed. Three days after the trauma, he was seen at a Trauma Center. Clinical and radiographic examination revealed partial displacement of tooth 11 out of the alveolus in the axial direction, occlusal changes, local pain, gingival bleeding, and tooth mobility. Prophylaxis and occlusal adjustment were performed, followed by the installation of a flexible splint, later replaced by a rigid one. Nine months after the accident, the rigid splint was removed, and the tooth showed no mobility or inflammatory signs, and it maintained a positive response to the pulp sensitivity test. Follow-up continued without complications, observing root development until apical closure with partial calcified tissue neoformation (possibly dentin and bone tissue) inside the canal. Conclusion: Although delayed, the treatment provided satisfactory results, preserving the pulp tissue and allowing for root apex closure, but it highlights the importance of emergency care training for managing dental traumas.
