Abstract:
Furcal perforation is usually undesirable and unfortunate incident commonly encountered during an endodontic access cavity or exploration of orifices of canal/s. A randomized control trial was con-ducted on 90 patients with furcal perforation. The objective was to compare effectiveness of Mineral Trioxide Aggregate (MTA) with Calcium Hydroxide in furcal repair in lower molars. radiographic assessment was done at 3 and 6months interval.the collected data was analyzed using SPSS version 14. 90 patients with furcal perforation divided into group A and group B with 45 patients in each group. Group A was treated with MTA and Group B with Calcium Hydroxide respectively. After 3 &6 months, a radiographic effectiveness was considered with the resolution of peri-radicular lesion. In group A, 43 patients showed complete recovery (success rate 95.6%). In Group B, 21 patients showed complete recovery(success rate 46.6%). It was concluded, MTA was better material for repair of furcal perforation than Calcium hydroxide
