title: Repair of perforating internal resorption with mineral trioxide aggregate: a case report.
abstract: A case of internal resorption with buccal perforation was found in a maxillary central incisor. Because of the extensive lesion and continuous exudation, surgical intervention was used. The apical third was obturated with gutta-percha, and the perforated lesion was repaired with mineral trioxide aggregate. The residual canal space was filled by thermoplasticized gutta-percha technique, and the coronal cavity was restored with composite resin. The symptoms and signs ceased, and the results were satisfactory at 1-year follow-up.
