Identification of the osteoprotegerin/receptor activator of nuclear factor‐kappa B ligand system in gingival crevicular fluid and tissue of patients with chronic periodontitis

Abstract

These findings imply that in this cross-sectional study of GCF, RANKL, IL-6 and OSM were all prominent in periodontitis sites, whereas OPG was inconsistently found in a few samples of diseased sites but was undetectable in any of the control sites. The results also imply that the expression of RANKL was positively correlated with IL-6 and OSM in the GCF.
