The relationship between oral health and diabetes mellitus.

BACKGROUND: The term "diabetes mellitus" describes a group of disorders characterized by elevated levels of glucose in the blood and abnormalities of carbohydrate, fat and protein metabolism. A number of oral diseases and disorders have been associated with diabetes mellitus, and periodontitis has been identified as a possible risk factor for poor metabolic control in subjects with diabetes.
METHODS: The authors reviewed the literature to identify oral conditions that are affected by diabetes mellitus. They also examined the literature concerning periodontitis as a modifier of glycemic control.
RESULTS: Although a number of oral disorders have been associated with diabetes mellitus, the data support the fact that periodontitis is a complication of diabetes. Patients with long-standing, poorly controlled diabetes are at risk of developing oral candidiasis, and the evidence indicates that periodontitis is a risk factor for poor glycemic control and the development of other clinical complications of diabetes. Evidence suggests that periodontal changes are the first clinical manifestation of diabetes.
CONCLUSIONS: Diabetes is an important health care problem. The evidence suggests that oral health care providers can have a significant, positive effect on the oral and general health of patients with diabetes mellitus.
