title: A cross-sectional survey of dental caries, oral hygiene, and Helicobacter pylori infection in adults.
abstract: We explored the epidemiological risk factors for dental caries to help explain differences in the prevalence of adult dental caries. We examined 841 people for the presence of Helicobacter pylori in their dental plaque and for dental caries. Of the 841 subjects, 574 (68.25%) were infected with H pylori, and 516 (61.36%) were diagnosed with dental caries. Among the 574 subjects with H pylori, the prevalence of dental caries was 73.52% (422/574), while the prevalence among the 267 cases without H pylori was 35.21% (94/267). A correlation existed between the presence of H pylori and the occurrence of dental caries (χ(2) = 112.8, P < .01, odds ratio = 5.110, 95% confidence interval = 3.740-6.982). The 574 persons with H pylori had a higher mean dental plaque index than those without. In conclusion, H pylori infection in the oral cavity is associated with dental caries and poor dental hygiene.
