The Relationship Between Periodontal Disease Attributes and Helicobacter pylori Infection Among Adults in the United States

OBJECTIVES: 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.
