Repair of Iatrogenic Perforation with Mineral Trioxide Aggregate under operating microscope: a one year follow up

Emmanuel João Nogueira Leal Silva, Daniel Herrera Morante, Eduardo José Souza-Junior


Perforations are significant iatrogenic complications of endodontic treatment lead to endodontic failure. Mineral trioxide aggregate (MTA) has been regarded as an ideal material for perforation repair, retrograde filling, pulp capping and apexification. This case report presents a perforation repair in a mandibular second pre-molar using MTA. The teeth were endodontically retreated and coronally restored with composite resin. The one year follow  up with the absence of periradicular radiolucent lesions, pain, and swelling along with functional tooth stability shows good prognosis.
