ineral Trioxide Aggregate as Repair Material for Furc erforation: Case Series

3 F a bstract he purpose of treating furcal perforation is to sea rtificial communication between the endodontic spa nd the periradicular tissue to prevent alveolar b esorption and damage to the periodontal ligame hese complications are not infrequent in cases urcal and/or old perforations, which show a w rognosis than fresh, small, coronal, and apical pe ations. Mineral trioxide aggregate (MTA) is wid sed to seal perforations because of its biocompatib nd sealability. Ten cases of furcal perforation w elected at the department of Endodontics, Univer f Florence. All the perforations were cleaned w aOCl, EDTA, and ultrasonic tips and sealed with ithout internal matrix. Finally, the teeth were e dontically treated and coronally restored. Clinical a adiographic follow-ups were done at 6 months, 1 years, and 5 years. After 5 years, the absen eriradicular radiolucent lesions, pain. and swelli long with functional tooth stability indicated a essful outcome of sealing perforations in 9 out o eeth. O n e patient dropped out of the study after -year follow-up and could not be contacted urther recalls. The results confirm that MTA with atrix provides an effective seal of root perforat nd clinical healing of the surrounding periodon issue. (J Endod 2008;34:1130 –1133)
