title: Is there a relationship between rheumatoid arthritis and periodontal disease?
abstract: OBJECTIVE
  The aim of this study was to determine whether there is a relationship between disease experience of rheumatoid arthritis and periodontal disease.
  
  
  METHODS
  1,412 individuals attending the University of Queensland's School of Dentistry were assessed for the prevalence of periodontal disease and rheumatoid arthritis. Analysis of data obtained from a self-reported health questionnaire and dental records was carried out and included: number of individuals referred for advanced periodontal care (test group); number of individuals attending for routine dentistry; determination of rheumatoid arthritis, cardiovascular disease and diabetes mellitus through self-reporting and assessment of prescription medications; assessment of periodontal disease through assessment of existing oral radiographs.
  
  
  RESULTS
  In patients referred for periodontal treatment, the prevalence of self-reported rheumatoid arthritis was 3.95% which is significantly higher than that seen in patients not referred for periodontal treatment (0.66%) and also that reported in the general population (1%). Of those referred patients with rheumatoid arthritis, 62.5% had advanced forms of periodontal disease. These results were mirrored in the results of the self-reported prevalence of cardiovascular disease and diabetes mellitus which was consistent with the published higher prevalence in periodontal patients.
  
  
  CONCLUSIONS
  Based on data derived from self-reported health conditions, and not withstanding the limitations of such a study, we conclude that there is good evidence to suggest that individuals with moderate to severe periodontal disease are at higher risk of suffering from rheumatoid arthritis and vice versa.
