Evaluation of Advanced PRF Combined With Nano-crystalline Hydroxyapatite for Management of Grade II Furcation Defects

Clinical and Radiographic Evaluation of Advanced Platelet Rich Fibrin Combined With Nano-crystalline Hydroxyapatite Bone Substitute for Management of Mandibular Molar Grade II Furcation Defects

this study is to evaluate the use of advanced platelet rich fibrin (A-PRF) + nano-crystalline hydroxyapatite bone substitute combined with open flap debridement (OPD) versus open flap debridement alone in the management of mandibular molar grade II defects.

In the management of mandibular molar grade II furcation defects, no difference exists in gain of horizontal clinical attachment level between the use of advanced platelet rich fibrin (A-PRF) + with nano-crystalline hydroxyapatite bone substitute combined with open flap debridement (OPD) and open flap debridement (OPD) alone .
