BACKGROUND Class II furcation is a significant clinical problem in dentistry. Its presence indicates advanced periodontitis. Different xenografts are available for the treatment of furcation involvement. Platelet concentrates that have been assimilated have a high concentration of growth factors, which has the added benefit of improving and accelerating healing. This study aims to compare the evaluation of effectiveness of T-PRF with xenograft and collagen membrane with xenograft in class II furcation defects. METHODS A one-year timeframe is going to be utilized to carry out the planned protocol, which is a randomised clinical trial. According to the inclusion criteria, 26 systemically healthy patients with class II furcation defects in mandibular molars will be included in the study. In Group I, xenograft and T-PRF (test group) will be condensed and in Group II, xenograft and collagen membrane (control group) will be condensed after the complete debridement of the furcation defect. Plaque index (PI), papillary bleeding index (PBI), Periodontal pocket depth (PPD), relative attachment level (R-CAL) and relative gingival marginal level (R-GML) will be evaluated as the clinical parameters. Cone-beam computed tomography (CBCT) will be performed to measure furcation height (FH), furcation width (FW), and furcation depth (FD) defects of mandibular molars. Data from each group will be evaluated at the time of surgery (baseline), and three and six months after the surgery. EXPECTED OUTCOMES Using xenograft (FIX OSS) combined with T-PRF, the authors anticipate better outcomes for class II mandibular furcation defects (test group). Improved clinical and radiographic outcomes in terms of PPD, R-CAL, R-GML and FH, FW, FD, are anticipated. CONCLUSIONS Using xenograft in combination with the T-PRF procedure is anticipated to have a better combined effect on periodontal parameters, including hard tissues and soft tissue outcomes.
