Gingival crevicular fluid levels of RANKL and OPG after placement of collagen membrane with simvastatin in the treatment of intrabony defects in chronic periodontitis

The aim of this study was to estimate the Receptor activator of nuclear factor kappa-B ligand (RANKL) and Osteoprotegrin (OPG) levels in gingival crevicular fluid (GCF) after placement of collagen membrane with simvastatin in intrabony defects.Sixty subjects were grouped according to the treatment plan as Group I and Group II.
