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.
我们探讨了龋齿的流行病学危险因素，以帮助解释成人龋齿患病率的差异。我们检查了 841 人的牙菌斑中是否存在幽门螺杆菌和龋齿。在这 841 名受试者中，有 574 名（68.25%）感染了 H pylori，有 516 名（61.36%）被诊断患有龋齿。在 574 名感染 H pylori 的受试者中，龋齿的患病率为 73.52%（422/574），而在 267 名未感染 H pylori 的受试者中，龋齿的患病率为 35.21%（94/267）。H pylori 的存在与龋齿的发生之间存在相关性（χ(2) = 112.8，P <.01，优势比= 5.110，95%置信区间= 3.740-6.982）。感染 H pylori 的 574 人牙菌斑指数均值高于未感染者。总之，口腔 H pylori 感染与龋齿和口腔卫生不良有关。
