Clinical effects of supragingival plaque control on uncontrolled type 2 diabetes mellitus subjects with chronic periodontitis

ABSTRACT

Aim: To determine the clinical changes occurred in chronic periodontitis patients presentinguncontrolled type 2 diabetes mellitus after a supragingival plaque control period. Methods:Subjects presenting generalized chronic periodontitis were divided into two groups: Non-diabetics(n=20) – healthy subjects presenting chronic periodontitis; and Diabetics (n=14) – subjects withuncontrolled type 2 diabetes mellitus presenting chronic periodontitis. All subjects went through 28days of supragingival plaque control - ST - (including prophylaxis, calculus removal, extractionof hopeless teeth and oral hygiene instructions) and were evaluated at baseline and after 28 daysby the following parameters: Full-Mouth Plaque Score (FMPS) and Full-Mouth Bleeding Scores(FMBS), Periodontal Probing Depth (PPD), Gingival Recession (GR) and Clinical AttachmentLevel (CAL). ANOVA/Tukey’s test and Student’s t test were used for data analysis. Results: Nostatistically significant differences (p>0.05) between groups were observed at baseline for anyparameter. Both groups presented a significant reduction in FMPS and FMBS after 28 days(p<0.05), but no statistically significant difference was found (p>0.05) between groups. Clinically,only the Non-diabetic group showed a significant improvement after ST, in PPD of initially deeppockets (p<0.05). However, no change in the clinical parameters was observed in the diabeticsubjects (p>0.05). Conclusions: It may be concluded that uncontrolled diabetes mellitus reducesperiodontal changes in the supragingival plaque control regimen of subjects presenting withchronic periodontitis.
