Abstract
The aim of the present randomized controlled clinical study was to evaluate the clinical outcomes in terms of gain in H-CAL, V-CAL and PPD reduction following the application of advanced platelet rich fibrin (A-PRF) + nano-crystalline hydroxyapatite bone substitute (n-HA) versus open flap debridement (OFD) alone in the management of mandibular molar grade II furcation defects
