Summary

This study looks at whether routine blood sugar testing during dental checkups can help find hidden high blood sugar in people with advanced gum disease. About 300 adults with severe gum disease will get a simple finger-prick blood test during their dental visit. The goal is to see how common undetected high blood sugar is in this group and whether adding this test to dental care is helpful and acceptable.
