Aim- Diabetes mellitus and chronic periodontitis are the most common chronic diseases in the adult world population. Many people suffering from diabetes around the globe do not know that they have diabetes. A dental / periodontal check up or treatment provides an ideal opportunity to screen for the patient particularly those who are at risk for diabetes mellitus, hypertension etc. Hence, this study aims to use gingival crevicular blood to obtain glucose level reading and compare it with glucose reading from capillary finger blood. Simultaneously chair side glycosylated hemoglobin measurement will be noted to correlate with the above two methods of blood glucose readings and to determine if gingival crevicular blood could be used as screening method for diabetes in a patient with gingivitis and periodontitis. Methods-60 subjects, 20 with chronic periodontitis (Group I), 20 with aggressive periodontitis (GroupII), 20 with chronic gingivitis (GroupIII) were included in this study, gingival crevicular blood, Capillary finger blood reading with glucometer and Glycosylated hemoglobin were compared. Results- Of all the 60 patients who participated in study; 2 patients were found to a have higher random blood glucose level, one in Group II and one in Group I, those patients were referred to physician for further detailed investigation. Conclusion: Gingival crevicular blood glucose and glycated hemoglobin can be effectively measured in dental settings by using chairside kits to screen for undiagnosed diabetes patients as well as to check glycemic control in diabetic patients. These tests can be performed effectively in community surveys as these tests gives readings which are rapid and accurate.
