Receptor Activator of Nuclear Factor‐κB Ligand and Sclerostin Expression in Osteocytes of Alveolar Bone in Rats With Ligature‐Induced Periodontitis

Abstract

These results show that AB loss is accompanied by enhanced osteoclast formation and suppressed osteoid formation. Osteocytes express RANKL when osteoclast formation increases, and they express sclerostin when osteoid formation is suppressed. Conversely, osteocytic sclerostin expression decreases when osteoid formation increases. These findings suggest that osteocytes may be important in AB loss via RANKL and sclerostin expression in periodontitis.
