Methods: A cross sectional comparative study was conducted among 25-64 years old, 210 diabetic and 300 non diabetic subjects in Davangere city. Relevant and required information regarding demographic characteristics and diabetic status was obtained. Community Periodontal Index (CPI) and Loss of Attachment Index (LOA) were used to assess the periodontal status. Chi-Square test, Z-test and Multiple Logistic Regression Analysis were used for statistical analysis.

Results: There was a highly significant association between diabetic status and periodontal status (p<0.001). Severity of periodontal disease (Community Periodontal Index code ‘4’ and Loss of attachment code ‘1’) was high among diabetics compared to non diabetics (p<0.001).

Conclusion: The findings of this study suggest that diabetes contributes to severity of periodontal disease and underlines the need for preventive services for diabetic community, tailored to improve their glycemic control which contributes to prevention of diabetic periodontopathy.
