title: Surgical repositioning of a traumatically intruded permanent incisor in a patient with rheumatic fever: case report.
abstract: Intrusive luxation of permanent teeth is a relatively uncommon type of injury to the periodontal ligament. However, it is one of the most severe types of dentoalveolar trauma. By definition, intrusive luxation consists of the axial displacement of the tooth into the alveolar bone, accompanied by comminution or fracture of the alveolar bone. Here we report the treatment management of a traumatically intruded immature permanent central incisor by surgical repositioning undertaken in a 10-year-old child with rheumatic fever 10 days after sustaining a severe dentoalveolar trauma. The intraoral examination showed the complete intrusion of the permanent maxillary right central incisor and the radiographic examination revealed incomplete root formation. Prophylactic antibiotic therapy was prescribed and the intruded tooth was surgically repositioned and endodontically treated thereafter. The postoperative course was uneventful, with both clinically and radiographically sound conditions of the repositioned tooth up to 3 years and 2 months of follow-up. These outcomes suggest that surgical repositioning combined with proper antibiotic prophylaxis and adequate root canal therapy may be an effective treatment option in cases of severe intrusive luxations of permanent teeth with systemic involvement.
