Background and Aim: Furcation involvement is a condition in which the destruction of interradicular periodontium occurs in the branching area of multirooted teeth, for which different treatment modalities have been suggested. The aim of this study was to compare the response of grade II mandibular molar furcation defects to Bio-oss versus Platelet Rich Plasma (PRP) and Bio-oss treatment. Materials and Methods: In this randomized clinical trial, five patients with bilateral grade II furcation involvement of mandibular molars were selected from those referred to the School of Dentistry, Shahed University of Medical Sciences. The molars were treated with Bio-oss and PRP on one side and Bio-oss on the other side. Measurements of the probing pocket depth (PPD), and clinical attachment level (CAL) were recorded at baseline, 1.5 and 3 months after surgery. Wilcoxon signed-rank test was used for statistical analysis.Results: At 1.5 and 3 months after surgery, the mean PPD reduction in the middle area of the furcation, was 2.4±1.67 mm and 3±2.0 mm in the test and 1±1.22 mm and 1.1±0.89 mm in the control groups, respectively. The mean attachment gain at the same place was 1.6±0.54 mm at 1.5 months and 1.8±0.44 mm at 3 months in the test group, and 1.5±1.0mm at 1.5 months and 1.4±1.34 mm at 3 months in the control group. Conclusion: The results of this study showed no significant difference between treatment with Bio-Oss with and without PRP in regeneration of grade II furcation involvement.
