  • 1. Correlations between Inflammatory Status, Dietary Intake and Periodontal Health 
    David Powers
  • 2. Throughout the world people are constantly being diagnosed with chronic inflammatory diseases. Currently, in the medical field there are no non-invasive, relatively inexpensive methods of looking at inflammation throughout the body. This research focuses on the studying the potential for the mouth to be used as a gateway into looking at inflammation throughout the body as well as examining any correlations between one's diet and periodontal health. These two objectives are achieved through the following two research questions: Is there a correlation between inflammatory disease and periodontal health?; and Is there a correlation between one's diet and one’s periodontal health? In this study the periodontal health of participants with Rheumatoid arthritis and Diebetes Type-II were examined. Results show that the level of inflammation in one's diet does have an effect of one's periodontal health and participants with an inflammatory disease have worse periodontal health than those without.
  • 3. Each year huge population diagnosed with chronic inflammatory disease
    Some common inflammatory diseases include: Arthritis, Crohn’s, Parkinson & diabetes type 2
    Estimated by 2030 about 67 million Americans 18 and older will have doctor diagnosed Arthritis
    Currently no inexpensive, non-invasive methods of looking at inflammation throughout body
    In study published in 2009 it was participants with rheumatoid arthritis had an increased prevalence of Periodontitis
    Study conducted in Italy found correlation between poor periodontal health and coronary heart disease
  • 4. In study testing the effect of treating periodontal disease on cardio vascular markers it was found that treating one's periodontal health may have an impact on reducing inflammation in one's body
    In final study it was found that certain dietary patterns may have an effect on one’s inflammation
    In order to classify diets according to inflammatory/anti-inflammatory effects on the body Inflammatory Factor Rating(IFR) used
    IFR gives each food a number according to factors such as amount and type of fat, essential fatty acid, vitamins, minerals and antioxidants, glycemic index, and anti-inflammatory compounds
    Periodontal health tested through Gingival Index
    Background Cont.
  • 5. Research Questions
    Is there a correlation between inflammatory disease and periodontal health?
    Is there a correlation between diet and the degree of inflammation in ones gums?
    Inflammatory status of participants (with or without Osteoarthritis/Type-II Diabetes)
    IFR of participants
    Periodontal health
    Problem Statement
  • 6. It has been hypothesized that if one has inflammatory disease, then they will also have poor periodontal health.
    It is predicted that if one has a diet containing "inflammatory foods," then they will have more inflamed gums than one who has a diet containing "anti-inflammatory foods."
  • 7. Procedures
    Research Question1
    20 with Arthritis, 20 with Diabetes type 2 & 20 without any inflammatory disease
    Research Question2
    50 participants ages 40-60
  • 8. Data
    Inflammatory Status vs. Average Periodontal Health
    Diet vs. Average Periodontal Health
  • 9. Charts
  • 10. Charts
  • 11. Charts
  • 12. Part One
    Statistical Analysis
    Part Two
    Correlation Coefficient: -0.4978668
  • 13. Hypothesis predicting that participants that had an inflammatory disease would have worse periodontal health than those free of all disease was supported by data
    Supported by study conducted in 2009 that found a relationship between Type-II Diabetes and Periodontitis
    Hypothesis predicting the lower the IFR of one’s diet, the worse one’s periodontal health was supported as well
    Supported by study that found participants that ate diets with inflammatory foods also seemed to have more inflammation througout the body
    Both sets of data were statistically significant
    Part two had a moderate correlation
  • 14. Dentists have the ability to estimate level of inflammation throughout the body simply by examining periodontal health
    If threat of high inflammation exists dentist can recomment patients get blood tests
    May prevent formation of an inflammatory disease/ warn patients if their inflammatory disease is severe
    Can recommend an anti-inflammatory diet to patients to lower inflammation
  • 15. Several errors made throughout study that can be improved
    Oral hygiene of participants was not controlled and in future research should be
    Gender and ethnicity not controlled & in future research will be
    Gingival index based largely off qualitative observations
    Use of Periodontal Index may improve accuracy
    Periodontal index tests for depth of gums
    In future research may be interesting to test effect of other factors on inflammation such as exercise
    Also interesting to look at other inflammatory diseases
