Numerous cross-sectional epidemiological studies suggest that obesity is associated with periodontal disease.(3) A longitudinal study published in the
Journal of Dental Research tested whether body mass index (BMI) was related to the development of periodontal disease in a sample of employed Japanese participants.(4) BMI is used to assess general body composition, and it is also an indicator of underweight, overweight, and obesity. The results demonstrate a dose-response relationship between BMI and the development of periodontal disease in a population of Japanese individuals. A 2005 study provided some evidence for how obesity may affect periodontitis.(5) The researchers hypothesized that obesity could affect periodontitis through an inflammatory pathway. They found that in adults representing the lowest and highest quartiles of BMI, the levels of tumor necrosis factor α and soluble tumor necrosis factor α receptors were found in those individuals with the highest quartiles of BMI, suggesting that tumor necrosis factor α and possibly other inflammatory mediators are elevated in obesity. This may contribute to increased inflammatory response to periodontal pathogens and, therefore more severe periodontitis. Since both obesity and periodontal diseases can be prevented, it is our duty to counsel our patients in self care, including nutrition.
