The Effect of Non-Surgical Periodontal Treatment on Bone Metabolism in Type 2 Diabetes and Systemically Healthy Individuals

Study Overview
=================
Brief Summary
-----------------
In this study, it was concluded that sclerostin and irisin may be alternative markers for evaluating the effectiveness of periodontal treatment and healing of periodontal tissues by affecting bone metabolism.

Detailed Description
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of bone metabolism biomarkers in different periodontal conditions | The levels of bone metabolism markers (such as sclerostin, irisin, IL-6, TNF-a, RANKL/OPG) in the gingival crevicular fluid of individuals with different periodontal conditions were compared using the ELISA (Enzyme Linked İmmünosorbent Assay) test, and the relationship of these markers with periodontal status was examined. | baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Probing pocket depth | Probing pocket depth(PPD) was measured for determining the severity of the disease and clinical outcome. High probing depth shows more severe periodontal disease. | baseline | 
| gingival index | The differences in gingival index scores between periodontally healthy and periodontitis.The gingival index was recorded for determining and classifying gingival status. The gingival index (Gİ) scores each site on a 0 being normal and 3 being severe inflammation characterized by edema, redness, swelling and spontaneous bleeding. | baseline | 
| Plaque index | The differences in plaque index scores between periodontally healthy and periodontitis. Plaque index (PI) was recorded for determining and classifying oral hygiene status. The plaque index (PI) scores each site on a with 0 being no plaque in gingival area and 3 abundance of soft matter within the gingival pocket and/or on the gingival margin and adjacent tooth surface. | baseline |
