Parendodontic surgery — apicoectomy and simultaneous obturation of root canals with mineral trioxide aggregate (MTA): case report

Bruna Kelly Fehlberg, Graziella Bittencourt

Introduction: When conventional root canal treatment does not achieve the desired results, paraendodontic surgery should be performed to remove the causes of the persistent periapical cyst, preserve the tooth, contribute to the adequate functioning of the stomatognathic system and return health and wellbeing to the patient. Methods: A 27-year-old male presented with the right maxillary lateral incisor (tooth 12) with persistent exudate even after treatment of the root canal and the exchange of intracanal medication using calcium hydroxide paste. In the present clinical case, paraendodontic surgery was performed with the simultaneous filling of the root canal. After curettage of the cyst and apicoetomy, the root canal was filled with mineral trioxide aggregate (5 apical mm) through the pulp chamber. Results: The histopathological exam revealed a secondarily infected cyst. Conclusion: The surgical techniques employed were adequate for the present case, as demonstrated both clinically and radiographically through the formation of new bone and the absence of symptoms, confirming the successful treatment of the case.
