Background: Periodontitis is considered to be an established risk factor for diabetes. Identification of individuals with diabetes and pre-diabetes is important to reduce diabetes-related complications including periodontitis. Knowledge of the diabetic status of dental patients, especially those with periodontal disease, is important as it may alter progression of periodontal disease. Objective: To identify the subjects with undiagnosed diabetes or prediabetes conditions. Material and Methods: Total of 120 subjects were included in which 60 were healthy subjects and 60 were chronic periodontitis subjects. All subjects were provided with questionnaires concerning their general health along with evaluating their body mass index (BMI), waist circumference and also fasting blood sugar (FBS) and postprandial blood sugar (PPBS) levels. They also underwent periodontal examination like probing pocket depth (PPD) and clinical attachment level (CAL). Results: The waist circumference was slightly higher and was statistically significant in case group. The value of BMI in case and control was not statistically significant. FBS and PPBS values were comparatively more in case group. A significant positive correlation was observed when correlation was done between all parameters in case and control group, comparing FBS and PPBS values. Conclusion: FBS and PPBS levels were slightly elevated in cases than in controls. Further studies are needed to determine whether the estimation of FBS and PPBS can improve early diagnosis and the management of pre diabetes and diabetes. Individuals with undiagnosed diabetes and prediabetes can be identified in the dental office by simple chair-side analysis of FBS and PPBS levels
