Effect of unintentionally extruded mineral trioxide aggregate in treatment of root perforation with periradicular lesion: a case report

This case report describes the effect of unintentionally extruded mineral trioxide aggregate (MTA) into periradicular lesions on the prognosis of periradicular healing in maxillary right molar with periradicular lesion. A 39–year-old male patient with a periradicular lesion from the root perforation of his maxillary right first molar was referred to our Department. A root canal retreatment was performed and the root perforation was filled with MTA. During this procedure, an unintentionally extrusion of MTA into the periradicular lesion occurred. At follow-up, the tooth was asymptomatic and at radiography a repair of the lesion was evident. No endodontic surgical treatment was necessary. In this case the healing was possible despite the extrusion of the MTA. This might be due to the biologic properties of the MTA.
