Association Between Periodontitis and Impaired Fasting Glucose and Diabetes

OBJECTIVE: Many studies have reported that periodontal disease is associated with diabetes, but its relation with impaired fasting glucose (IFG) has been understudied. This study investigated the relationship between chronic periodontitis, IFG, and diabetes in the U.S. population. RESEARCH DESIGN AND METHODS: Participants in the National Health and Nutrition Examination Survey III, aged ≥20 years, who received periodontal examinations and provided blood samples (n = 12,254) were grouped into quintiles of mean clinical attachment loss (CAL) and pocket depth, with the lowest category being the reference. Plasma fasting glucose was categorized into three groups (normal,
