REPAIR OF FURCAL PERFORATIONS WITH MINERAL TRIOXIDE AGGREGATE - 2 CASE-REPORTS

Furcal perforation is an unfortunate incident that can: occur during r oot canal therapy or post preparation of multirooted teeth. Studies ha ve shown that the materials currently used to repair these iatrogenic accidents are inadequate. The poor prognosis of furcation perforations is probably due to bacterial leakage or lack of biocompatibility of r epair materials. On the basis of the recent physical and biologic prop erty studies of the newly introduced mineral trioxide aggregate, this material may be suitable for closing the communication between the pul p chamber and the underlying periodontal tissues. These case reports s upport this hypothesis.
