One of the major complications of diabetes is periodontal disease, a chronic infection of tissues supporting the teeth and a major cause of tooth loss. Adults with diabetes have both a higher prevalence of periodontal disease and more severe forms of the disease, contributing to impaired quality of life and substantial oral functional disability. In addition, periodontal disease has been associated with development of glucose intolerance and poor glycemic control among adults with diabetes. Regular dental visits provide opportunities for prevention, early detection, and treatment of periodontal disease among dentate adults (i.e., those having one or more teeth); moreover, regular dental cleaning improves glycemic control in patients with poorly controlled diabetic conditions. One of the national health objectives for 2010 is to increase the proportion of persons with diabetes who have an annual dental examination to 71% (revised objective 5-15). To estimate the percentage of dentate U.S. adults aged > or =18 years with diabetes who visited a dentist within the preceding 12 months, CDC analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS) surveys for 1999 and 2004. This report describes the results of that analysis, which indicated that, in 2004, age-adjusted estimates in only seven states exceeded 71% and estimated percentages for four states and District of Columbia (DC) increased significantly from their levels in 1999. The findings underscore the need to increase awareness and support for oral health care among adults with diabetes, including support for national and state diabetes care management programs.
