Perforations are cited as the second greatest cause of treatment failure next to improper obturation. Failure to seal the perforation permits rapid breakdown of periodontium and eventual loss of tooth. A patient presented with the chief complaint of caries, pain and pus discharge in mandibular right first molar. He had got root canal treatment started from a dentist approximately three months ago but had no relief. Clinical and radiographic examination revealed perforation in the furcating area. Mineral trioxide aggregate was used to seal the perforation non-surgically. Both clinical and radiographic evaluation of the involved tooth after three months revealed evidence of periradicular healing. Mineral trioxide aggregate is one of the most interesting new products introduced in endodontics. Besides perforation repair, it use has been expanded for various procedures such as pulp capping, apexification, root end filling. Though initial reports seem to be very favourable mote studies are still required to establish its efficacy.
