Long-Term Success of Regenerative Endodontic Treatment in Managing Traumatized Teeth: A Case Report With Seven-Year Follow-Up.

Traumatic injuries to maxillary incisors often result in complex dental complications, such as pulp necrosis and periapical pathology, particularly in young patients. Traditional root canal treatments may prove insufficient, especially for immature teeth requiring apexification. Regenerative endodontic treatment (RET) presents a promising alternative, aiming to eliminate infection while fostering root development and tooth vitality. This case report illustrates the successful management of a necrotic-infected traumatized maxillary incisor in a seven-year-old girl using RET. The treatment involved a meticulously planned protocol comprising disinfection, induction of bleeding, and placement of a calcium-enriched mixture (CEM) cement plug, followed by composite restoration. Remarkably, despite the initial detection of an endodontic lesion in the postoperative radiograph, the clinical outcomes remained aesthetically pleasing, with subsequent radiographs revealing regression of the apical lesion and complete tooth maturation over the seven-year follow-up period. This case highlights the efficacy and feasibility of RET using CEM in managing infected, traumatized teeth, emphasizing its potential for long-term healing and functional restoration. The absence of tooth discoloration further underscores the benefits of utilizing specific materials and protocols.
