Treatment of lateral root perforation with mineral trioxide aggregate: a case report.

Root perforations are undesired complications of endodontic treatment which result in loss of integrity of the root and further destruction of the adjacent periodontal tissues. In recent literature mineral trioxide aggregate (MTA) has been regarded as an ideal material for perforation repair. In this case iatrogenic perforation was observed in a maxillary central incisor. It was not possible to reach the perforation from the access cavity due to the angulation and excessive bleeding even though the root canal was filled with calcium hydroxide paste between appointments. Therefore, surgical intervention was preferred. After the root canal was filled with gutta percha and AH plus, the perforation site was subsequently sealed with MTA. The restoration was made with strip crown and composite resin. The symptoms were ceased and the results were satisfactory after 15 months follow-up.
