The Third National Health and Nutrition Examination Survey showed that obesity is a predictor of periodontal disease. Researchers also found that the severity of the disease increased in tandem with insulin resistance.
Robert Genco of the University of Buffalo and an editor of the Journal of Periodontology said that people with a high body mass index produce cytokines or hormone-like proteins that help create inflammation and insulin resistance. He said that the cytokines are also associated with periodontal inflammation, contributing to further insulin resistance.
Genco and his research team also found that diabetics with periodontal disease have a higher mortality rate than those who do not have periodontal disease.
