Effect of non‐surgical periodontal treatment on gingival crevicular fluid and serum leptin levels in periodontally healthy chronic periodontitis and chronic periodontitis patients with type 2 diabetes mellitus

摘要

Abstract Aim The aim of the present study was to evaluate the effect of non‐surgical periodontal therapy (NSPT) on gingival crevicular fluid (GCF) and serum leptin levels and glycemic status in periodontally healthy patients with chronic periodontitis (CP) with and without type 2 diabetes mellitus (T2DM). Methods Ninety patients were divided into three groups: periodontally healthy (group 1), CP (group 2) and CP with T2DM (group 3). The groups were evaluated for clinical parameters of probing pocket depth (PPD), clinical attachment level (CAL), plaque index, gingival index, biochemical parameters of GCF, serum leptin levels, and glycemic status pre‐ and post‐NSPT. Results The baseline PPD and CAL for group 2 was 4.98?±?0.49?mm and 5.35?±?0.55?mm, respectively; for group 3 it was 5.60?±?0.38?mm and 6.01?±?0.38?mm, respectively. There was a considerable reduction in these parameters post‐NSPT, with group 2 showing better resolution. Pretreatment serum leptin levels revealed increasing values from group 1 to group 3 and decreasing GCF values from group 3 to group 1, exhibiting an inverse relationship. Group 3 also showed an improvement in glycemic status post‐NSPT. Conclusion NSPT was effective in improving clinical parameters, increasing GCF, reducing serum leptin levels, and also improving glycemic status in patients with CP and CP with T2DM.
