Purpose: The purpose of study was to compare blood glucose in capillary finger-prick blood and gingival crevice blood usinga self-monitoring blood glucose device among patients with gingivitis or periodontitis.
Methods: Thirty patients with gingivitis or periodontitis and bleeding on probing (BOP) were chosen. The following clinicalperiodontal parameters were noted: probing depth, BOP, gingival bleeding index, and periodontal disease index. Blood sampleswere collected from gingival crevicular blood (GCB) and capillary finger-prick blood (CFB). These samples were analyzedusing a glucose self-monitoring device.
Results: Descriptive statistical analysis has been carried out in the present study. Data were analyzed using a Pearson’s correlationcoefficient and Student’s t-test. A r-value of 0.97 shows very strong correlation between CFB and GCB, which was statisticallyhighly significant (P<0.0001).
Conclusions: The authors conclude that GCB may serve as potential source of screening blood glucose during routine periodontalexamination in populations with an unknown history of diabetes mellitus.
