Delayed Treatment and Favorable Outcome of the Complication Following Severe Dental Injuries: A Case Report

Abstract

Objective: Severe dental injuries that affect not only the pulp tissues, but also the periodontal ligament can have a negative impact on the long-term prognosis of permanent teeth. The purpose of this article is to introduce a clinical case of both intrusive and lateral luxations, discuss potential treatment options and highlight possible complications and management. Methods: A 35-year-old patient experienced significant dental and soft tissue trauma after falling face forward while riding an electric scooter. Upon clinical and radiographic examination, it was discovered that he had the intrusion of tooth 11 by 3-4 mm, an uncomplicated crown fracture of tooth 21, lateral luxations of teeth 12, 41, 42, as well as bruised and swollen upper and lower lips. Teeth 12, 11, 41 and 42 were surgically repositioned to their original positions and splinted with steel wire and light-cured composite resin for a 4-week period. After the splint was removed, root canal treatment of teeth 11,12,41,42 was initiated was initiated using calcium hydroxide as an intracanal medication and followed by root canal obturation with mineral trioxide aggregate and vertical compaction with warm gutta-percha. The postoperative periapical radiograph revealed external inflammatory root resorption with irregular mesial root surface of tooth 11. Results: After 15 months, the radiographs and clinical examination showed no signs or symptoms of endodontic pathology. Conclusion: This case report highlights the effective multidisciplinary treatment of traumatic lateral and intrusive luxation in permanent incisors, as well as the successful management of resultant external inflammatory root resorption.
