Objective To evaluate the effects of periodontal intervention on inflammatory cytokines, adiponectin, insulin resistance (IR), and metabolic control and to investigate the relationship between type 2 diabetes mellitus (T2DM) and moderately poor glycemic control and chronic periodontitis. Methods and Patients A total of 190 moderately poorly controlled (HbA1c between 7.5% and 9.5%) T2DM patients with periodontitis were randomly divided into two groups according to whether they underwent periodontal intervention: T2DM-NT and T2DM-T group. The levels of serum adiponectin, C-reactive protein (CRP), tumor necrosis factor a (TNF-alpha), interleukin-6 (IL-6), lipid profile, glucose, insulin, homeostasis model of assessment - insulin resistance (HOMA-IR) and homeostasis model assessment of beta-cell function (HOMA-beta) were measured at baseline and after 3 months. Results The levels of clinical periodontal variables, the probing depth, attachment loss, bleeding index, and plaque index were improved significantly in T2DM-T group after 3 months compared to T2DM-NT group (all p<0.01). After 3 months, the serum levels of hsCRP, TNF-alpha, IL-6, fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS) and HOMA-IR index decreased, and adiponectin was significantly increased in T2DM-T group compared to those in the T2DM-NT group (p<0.05 or p<0.01). Conclusion Periodontal intervention can improve glycemic control, lipid profile and IR, reduce serum inflammatory cytokine levels and increase serum adiponectin levels in moderately poorly controlled T2DM patients.
