Alterations of GCF Levels of Sclerostin and DKK-1 in Postmenopausal Osteoporosis

Summary

Symptoms of periodontal disease are tissue destruction and destruction of the alveolar bone which supports the tooth. Wnt way (wingless-type MMTV integration site family) plays a role in the regulation of bone homeostasis in periodontal disease-induced bone resorption. The Wnt / β-catenin signal is controlled by physiological antagonists, including dickkopf released from osteocytes-associated protein 1 (DKK-1) and sclerostin (SOST). Thus, Wnt inhibitors SOST and DKK-1 affect bone mass changes. Bisphosphonates used in osteoporous treatment are selective inhibitors of bone resorption. In the serum of postmenopausal osteoporotic women treated with bisphosphonate, short-term and decreased DKK-1 level during the treatment, and increased SOST in the late period were reported. Increased bone formation after bisphosphonate treatment in postmenopausal osteoporotic patients has been associated with increased serum SOST level. The aim of our study is to investigate the effect of bisphosphonate in patients with post-menopausal osteoporosis on the bone demolition metabolism in periodontally healthy and periodontally diseased tooth regions and gingival health with the clinical data by investigating the SOST and DDK-1 molecules that play role in bone destruction mechanism.
