The present study was aimed to assess the fasting and postprandial gingival crevicular blood (GCB) glucose and finger stick blood glucose measurements using a glucometer. A total of 30 subjects with periodontitis and positive bleeding on probing were considered. Subjects were instructed to report to the department after overnight fasting. Gingival crevicular blood samples were collected from anterior region showing bleeding on probing followed by finger stick blood sample collection. Then, the patients were instructed to take 75 gm of glucose and after 2 hours blood samples from two sites were collected similarly. Results were analyzed using unpaired t test and Pearson's correlation. Mean glucose levels form GCB and finger stick blood did not differ either during fasting or postprandial (p > 0.05). Significant correlation was found between GCB glucose levels and capillary finger stick blood (CFB) glucose levels during fasting (r = 0.946, p < 0.001) and postprandial (r=0.930, p < 0.001) blood estimation. Periodontal probing can be considered as an alternate noninvasive method of blood glucose estimation for screening of diabetes mellitus (DM). The technique described is safe, easy to perform, and helps to increase the frequency of diabetes screening in dental office. The GCB from probing can be a good source of blood for estimating blood glucose levels and screening for diabetes using portable glucose monitors. Also, it will be a simple and relatively inexpensive in office screening procedure for any patient suspected to have diabetes.
