Background: Most of the Indian population goes undiagnosed for diabetes due to unawareness. This will lead to more serious and long-term complications of diabetes. Thus, there is a critical need to increase opportunities for diabetes screening and early diabetes detection. Research has explored the dental office as a strategic venue of opportunity for glucose testing, examining the possibility of using gingival crevicular fluid (GCF) for diabetes screening. Aim: The aim of this study is to evaluate the reliability of gingival crevicular blood (GCB) to screen the diabetes. Methodology: Thirty patients were randomly selected based on bleeding on probing and probing depth. GCB and capillary finger blood (CFB) glucose levels were calculated using glucometer from patients. Data for glucose levels were statistically analyzed. Results: The correlation between GCB and CFB was high. Conclusion: GCB can be used as the screening test for diabetes in the dental office. Clinical Significance: GCB blood glucose level detection can be used as chairside screening test for diabetes patients
