Mineral trioxide aggregate as repair material for furcal perforation: case series
Abstract
The purpose of treating furcal perforation is to seal the artificial communication between the endodontic space and the periradicular tissue to prevent alveolar bone resorption and damage to the periodontal ligament. These complications are not infrequent in cases of furcal and/or old perforations, which show a worse prognosis than fresh, small, coronal, and apical perforations. Mineral trioxide aggregate (MTA) is widely used to seal perforations because of its biocompatibility and sealability. Ten cases of furcal perforation were selected at the department of Endodontics, University of Florence. All the perforations were cleaned with NaOCl, EDTA, and ultrasonic tips and sealed with MTA without internal matrix. Finally, the teeth were endodontically treated and coronally restored. Clinical and radiographic follow-ups were done at 6 months, 1 year, 2 years, and 5 years. After 5 years, the absence of periradicular radiolucent lesions, pain. and swelling along with functional tooth stability indicated a successful outcome of sealing perforations in 9 out of 10 teeth. One patient dropped out of the study after the 1-year follow-up and could not be contacted for further recalls. The results confirm that MTA without matrix provides an effective seal of root perforations and clinical healing of the surrounding periodontal tissue.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
