Platelet Rich Fibrin With 1% Metformin Gel for Treatment of Intrabony Defects

Summary

ABSTRACT: Background: Platelet-rich fibrin (PRF) is a second-generation platelet concentrate which releases various growth factors that promote tissue regeneration. Metformin (MF), a member of biguanide group has been shown to facilitate osteoblast differentiation and thus may exhibit a favourable effect on alveolar bone . Current study was designed to evaluate the combined efficacy of PRF and 1% MF gel with open flap debridement (OFD) in treatment of intrabony defects in chronic periodontitis (CP) subjects. Methods: One hundred and twenty subjects with single defects were categorized into four treatment groups: OFD alone, OFD with PRF, OFD with 1% MF and OFD + PRF+1% MF. Clinical parameters like site specific plaque index (PI), modified sulcus bleeding index (mSBI), probing depth (PD), relative attachment level (RAL) and gingival marginal level (GML) were recorded at baseline before surgery and 9 months post-operatively. Percentage radiographic intra-bony defect depth reduction was evaluated using computer-aided software at baseline and 9 months.
