Platelet-rich fibrin in combination with decalcified freeze-dried bone allograft for the management of mandibular degree II furcation defect: A randomised controlled clinical trial
Abstract
Background: Treatment of furcation involvement of molars with periodontal disease remains challenging and unpredictable. Platelet-rich fibrin (PRF) has received the attention of researchers due to its pleiotropic properties essential for periodontal wound healing. The osteoinductive property of demineralized freeze-dried bone allograft (DFDBA) has been successfully used in periodontal regeneration.
Aim: The present study aimed to explore the effectiveness of PRF alone and with DFDBA in the treatment of mandibular degree II furcation defects in subjects with chronic periodontitis.
Material and Methods: Patients treated were from the Department of Periodontology and Implantology, Institute of Dental Sciences, Bareilly. A total of 60 mandibular molars were treated with either open flap debridement (OFD) alone, PRF+OFDPRF+OFD combination or OFD+PRF+DFDBAOFD+PRF+DFDBA combination. The soft and hard tissue parameters such as vertical probing depth (VPD), vertical clinical attachment level (VCAL), gingival marginal level (GML), horizontal probing depth (HPD), vertical bone fill (VBF), horizontal bone fill (HBF) and furcation width (FW) were determined at baseline and 9 months postoperatively. A paired tt-test was conducted to assess the statistical significance between time period within each group for clinical and radiographic parameters. ANOVA and post-hoc Tukey’s tests were also conducted for intergroup comparison of soft and hard tissue parameters. Statistical significance was set at p<0.05p<0.05.
Results and Discussion: After 9 months, all treatment groups showed significant (p<0.001p<0.001) improvement in soft and hard tissue parameters, except GML in all the three groups and HBF and FW in the OFD group as compared to baseline. The mean VBF change was highest in the OFD+PRF+DFDBAOFD+PRF+DFDBA group (1.90+0.451.90+0.45) mm, followed by that in the PRF+OFDPRF+OFD and OFD groups (1.60+0.881.60+0.88 and 0.45+0.510.45+0.51mm, respectively).
Conclusions: It was shown that both PRF+OFDPRF+OFD and PRF+DFDBA+OFDPRF+DFDBA+OFD combinations were significantly advantageous for the management of mandibular degree II furcation defects. However, the PRF+DFDBA+OFDPRF+DFDBA+OFD combination has significantly greater benefits than PRF+OFDPRF+OFD combination in terms of VBF.
