Background: Iatrogenic perforations within the floor of the pulp chambers are undesirable complications and unfortunate incidents that occur most commonly during endodontic procedures. With the recent physical and biological property investigations of the generally new presented mineral trioxide aggregate, it can be said that this material might be appropriate for shutting the correspondence between the pulp chamber and underlying periodontal tissues.
Case presentation: A 27-year-old man presented to the clinic complaining of slight pain in tooth 36. The perforation of the molar tooth had been done in ER dental clinic four months ago. Periodontal surgery and removal of granulation tissue were performed, the perforation was cleaned with a saline solution and sealed with MTA, cotton pellet was placed and also a temporary filling. Finally, the tooth was endodontically treated and restored with amalgam build up and covered by the crown. After three months and six months follow up, there was no pain and swelling along with functional stability; radiograph showed an absence of periarticular radiolucency, and absence of lesion formation of PDL at the perforation site.
Conclusion: The applied treatment procedure is a successful method of sealing perforation.
