Bioactive material as treatment for complicated crown fracture in a permanent dental organ, 3-year follow-up.

Abstract

Introduction: Crown fractures represent the most frequent trauma in permanent dentition, in males between 7 and 20 years old, especially if there is an increased overjet. The restoration of the affected tooth is a priority due to its biological and functional value for the stomatognathic system and for the aesthetic and psychological implication in the patient. A thorough clinical and radiographic examination is important to correctly diagnose the affected area and provide adequate treatment. Fragment replacement is a current technique that can be mediated; within the first 15 days, or late; up to a month and a half after the trauma. The prognosis of a traumatized tooth will depend on the damage caused to the periodontal tissue, the extent of the fracture, the root development of the dental organ and the time elapsed until treatment was received.Clinical Report:A 9-year-old male presents a complicated coronary fracture in tooth 11 with two days of evolution. Treatment was performed in three appointments. 1. Complete prophylaxis and treatment of Cvek's pulpotomy filled with Biodentine. 2. Gingivoplasty of the area that prevented the repositioning of the dental fragment, 3. Repositioning of the coronary fragment with fluid resin. Clinical and radiographic follow-up has been maintained for 3 years. Conclusions:The results obtained with the conservative treatment of complicated crown fractures have been the maintenance of pulpal vitality and the preservation of all dental tissue, restoring function and aesthetics. Neither clinically nor radiographically is any damage or alteration observed after treatment.
