Significance of Gingival Crevicular Blood as an Innovative, Intraoral Diagnostic Tool for Estimation of Random Blood Glucose, Hba1c and C-Reactive Protein Levels in Undiagnosed Diabetic Population- A Systematic Review

Diabetes mellitus (DM) is a complex metabolic disorder characterized by chronic hyperglycemia. Diabetes mellitus (DM) is undiagnosed in approximately half of the patients actually suffering fromdisease. In addition, the prevalence of DM is more than twice as high in patients with periodontitis when compared to periodontally healthy subjects. Periodontitis is the sixth most common complication of diabetes making it a major risk factor influencing the incidence and severity of periodontal related problems. As a dental professional it is our duty to screen and diagnose diabetic population visiting us based on the clinical complaint and oral findings. Gingival crevicular blood (GCB) oozing out from the periodontal pocket during probing can be used to estimate the random blood glucose levels, HbA1c and C-Reactive Protein levels to identify patients unaware of their diabetic status. This review article throws light on the significance of GCB for evaluation of blood glucose levels for diagnosing undiagnosed diabetic population.
