Evaluation of the relative efficacy of autologous platelet-rich fibrin membrane in combination with β-tricalcium phosphate (Septodont- resorbable tissue replacement)™ alloplast versus β-TCP alloplast alone in the treatment of grade II furcation defects.

Abstract

Introduction:Platelet-rich fibrin (PRF) is considered as the second-generation platelet concentrate, contains combined properties of fibrin, platelets, leukocytes, growth factors, and cytokines that make it as healing biomaterial with incredible potential for hard tissue and soft tissue regeneration. The present study was aimed to evaluate the effectiveness of PRF with β-tricalcium phosphate (β-TCP) graft (R. T. R) and compare it with β-TCP allograft alone in the treatment of mandibular Grade II furcation defects.Material and Methods:A total of 20 mandibular Grade II furcation defects sites were assigned in the study and treated with either β-TCP alone (Group I) or β-TCP with PRF membrane (Group II). The clinical parameters analyzed were probing pocket depth (PPD), clinical attachment level (CAL), gingival recession (GR), horizontal defect depth (HDD), and vertical defect depth (VDD), recorded baseline and at 6 months reentry.Results:At 6 months, both groups showed statistically significant results for all parameters from their baseline value, although intergroup changes were statistically insignificant. In Group I, gain in CAL was 2.80 ± 1.40 and in Group II it was 3.00 ± 1.44. Bone fill in Group I was VDD (3.50 ± 2.12) and HDD (3.70 ± 0.67), whereas Group II showed VDD (3.70 ± 1.57) and HDD (4.0 ± 0.88), respectively. PPD reduction was higher in Group I (3.50 ± 2.27) than Group II (2.80 ± 1.93). At reentry GR was established, Group I showed higher GR (0.70 ± 0.67) and Group II (0.40 ± 0.52).Conclusions:Significant improvement was found in both groups, but the combination of PRF with β-TCP allograft led to more favorable improvement in the management of Grade II furcation defect except PPD.
