title: The relationship between periodontal disease attributes and Helicobacter pylori infection among adults in the United States.
abstract: OBJECTIVE
  We investigated the relationship between Helicobacter pylori infection and abnormal periodontal conditions.
  
  
  METHODS
  Data from the first phase of the third National Health and Nutrition Examination Survey were used. A total of 4504 participants aged 20 to 59 years who completed a periodontal examination and tested positive for H. pylori antibodies were examined.
  
  
  RESULTS
  Periodontal pockets with a depth of 5 mm or more were associated with increased odds of H. pylori seropositivity (odds ratio [OR] = 1.47; 95% confidence interval [CI] = 1.12, 1.94) after adjustment for sociodemographic factors. This association is comparable to the independent effects of poverty on H. pylori (OR = 1.54; 95% CI = 1.10, 2.16).
  
  
  CONCLUSIONS
  Poor periodontal health, characterized by advanced periodontal pockets, may be associated with H. pylori infection in adults, independent of poverty status.
