Aim: Periodontitis is often associated with diabetes mellitus and may be considered one of the chronic complications of this disease. Increasing evidence indicates that periodontal disease (gingivitis and periodontitis) has an adverse effect on glycemic control and participates in the pathophysiology of complications related to type 2 diabetes mellitus. Thus, this study aimed to evaluate the influence of obesity on clinical periodontal parameters of patients with type 2 diabetes mellitus with stage II or III periodontitis grade C after conventional periodontal treatment.
Methods: For this study, 36 patients, aged 25 to 65 years, were evaluated; 20 patients with type 2 diabetes mellitus and moderate to severe periodontitis (Non-Obese Group) and 16 patients with type 2 diabetes mellitus with obesity and moderate to severe periodontitis (Obese Group). These patients underwent conventional periodontal treatment and were evaluated using plaque index, probing depth, clinical attachment level, bleeding on probing and gingival crevicular fluid analysis, as well as laboratory tests of glycated hemoglobin, fasting glycemia, total cholesterol, and fractions of triglycerides. Periodontal and laboratory parameters were evaluated at baselineand six months.
Results: The results showed improvements in periodontal and clinical laboratory parameters(p less than 0.05) in the evaluated periods; however, the non-obese group presented significantly better results when compared to the obese group.
Conclusion: It can be concluded that the presence of obesity may hinder the improvement of periodontal clinical parameters after conventional periodontal treatment in patients with diabetes mellitus and periodontitis.
