Materials and methods: Twenty five patients (n=25) were selected from the outpatient clinic of the department of oral medicine and periodontology at Mansoura university's faculty of dentistry, 5 patients (n=5) were excluded as they didn't meet the inclusion criteria or met one or more of the exclusion criteria. The participants 20 patients exhibiting one buccal or lingual mandibular molar furcation defect were assigned into two treatment groups: group I (control group), group II (study group), 10 patients in each group. Patients in group I will be treated with open flap debridement, native collagen membrane and bovine bone graft particles. Patients in group II will be treated with open flap debridement, bovine pericardium membrane and bovine bone graft particles. Periodontal assessment (plaque index (PI), gingival index (GI), horizontal clinical attachment level (HCAL), vertical clinical attachment level (VCAL), gingival recession (REC) and probing depth (PD)) will be evaluated at baseline, 3 months and 6 months after periodontal treatment. Radiographic assessment using CBCT (bone loss in the horizontal direction (BL-H), bone loss in vertical direction (BL-V), length of the root trunk (RT), width of furcation entrance (FW) will be evaluated at baseline and 6 months after periodontal treatment.
