Diagnostic Efficacy of Gingival Crevicular Blood for Assessment of Blood Glucose Levels in Dental Office: A cross Sectional Study

Deepa Jatti Patil and Dhanyashri Kamalakkannan

Objectives: The gingival crevicular blood (GCB) obtained during routine periodontal probing may be a source for blood glucose measurements. The aim of this study was to compare gingival crevicular blood and fingerstick blood glucose measurements using a glucometer against the conventional laboratory methods.

Materials and Methods: The study group comprised of three groups. In the first group 30 patients with periodontitis and positive bleeding on probing were chosen. Blood samples of two sites intraorally were analyzed using a glucose self-monitoring device. The second and third group comprised of 50 diabetic and 50 non-diabetic patients. After testing fasting plasma glucose (FPG), fasting glucose levels in gingival crevicular blood (GCBG), and fasting capillary fingerstick blood (CFBG) samples were analyzed using same device.

Results: Significant correlation (r= 0.93, p<0.001) was found between gingival crevicular blood glucose levels and capillary finger stick blood glucose levels. Considerable correlation (r=0.75, p<0.001) was found between levels of fasting gingival crevicular blood glucose and fasting blood glucose both in diabetic patients and the normal population.

Conclusion: It is evident that the blood obtained during routine periodontal probing can be used for estimation of blood glucose levels. GCB can be used as a marker for blood glucose estimation using glucometer. The technique described is safe, easy to perform and helps to increase the frequency of diabetes screening in dental office.
