The Effect of Non-Surgical Periodontal Therapy on Sclerostin, Irisin, RANKL \ OPG, IL-6 and TNF-α Levels in Type 2 Diabetes and Systemically Healthy Individuals

Background: Diabetes and periodontitis are chronic inflammatory diseases with similar pathogenesis and clinical and immunological interrelationships. The aim of this study is to determine periodontal clinical parameters and sclerostin, irisin, Receptor Activator of Nuclear Factor κB Ligand (RANKL)/Osteoprotegerin (OPG), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels in gingival crevicular fluid (GCF) in individuals with type 2 diabetes and systemically healthy periodontitis and to evaluate the effect of non-surgical periodontal therapy on these clinical parameters and biomarkers.

Method: Within the scope of this study, applying to Necmettin Erbakan University Faculty of Dentistry Periodontology Clinic; A total of 50 individuals, including 25 patients with type 2 diabetes and periodontitis (DMP group) and 25 patients with systemically healthy and periodontitis (SSP group), were included in the study. After recording the clinical periodontal parameters (gingival index (GI), plaque index (PI), probing pocket depth (PPD), clinical attachment level (CAL)) of each individual included in the study, GCF samples were obtained and non-surgical periodontal therapy were completed. The individuals were invited to the controls 3 months later and the procedures for clinical periodontal measurements and DOS samples collection were repeated. Levels of biomarkers in DOS samples were determined by ELISA (Enzyme Linked Immunosorbent Assay) method.
