Surgical replacement of huge rate of root end amalgam filling with mineral trioxide aggregate angelus: A case report

BACKGROUND AND AIM: Surgical endodontics may sometimes fail despite using root-end filling materials (REFMs). In this case report, a symptomatic right maxillary first premolar underwent periradicular surgery (PS) for replacing huge rate of amalgam with mineral trioxide aggregate (MTA). CASE REPORT: A thirty-year-old healthy woman attended with the chief complaint of recurrent swelling and abscess in the periradicular region of maxillary premolar tooth and sensitivity to percussion. She had a history of PS in the past year. Periapical radiographic images showed a huge rate of amalgam used as REFM. The PS was performed again and the amalgam was replaced with MTA. Postoperative clinical and radiographic evaluation after 2 years showed no sign of abscess and no sensitivity to percussion and periapical pathosis. CONCLUSION: In this case report, replacing amalgam with MTA provided reasonable outcome up to 2 years after the treatment.
