H.elicobacter pylon is known as one of tH.e most common infecting bacteria and is infecting H.alf tH.e world¢¥s population. H.owever, tH.e exact mecH.anism of transmission is still unclear. TH.e dental plaque was suggested as a possible resorvoir in transmission route In tH.is report, dental plaques and posterior dorsal surface of tongue samples were collected from 62 randomly selected dyspeptic patients referred to tH.e division of gastroenterology, Yonsei University, Severance H.ospital. To determine tH.e prevalence of H. pylon 10 oral cavity and to assess tH.e role of dental plaque as a permanent resorvoir in transmission route, samples were analyzed for tH.e presence of H.. pylori witH. nested PCR TH.e results are summerized as follows:
1 In Study group (group of H.. pylori infected patients), eigH.t of 36 (22.2%) dental plaque samples and twelve of 36 (33.3%) posterior dorsal surface of tongue samples turned out to be positive. In Control group (group of H. pylon non-infected pH.tients), two of 26 (7.7%) samples of each. subgroup were positive.
2. The detection rate of H. pylon DNA in samples from Study group was significantly higher than in that from Control group (P ≶ 0.06). Comparison of T subgroups (group of posterior dorsal surface of toungue) showed significant difference in detection of H. pylori (P ≶0.05), whereas no difference was found between subgroup P (group of dental plaque) of Study group and that of Control group. 3 Statistical significance was observed in subgroup P from Study group and in Control group (P ≶ 0.01) when positivity of H. pylori In each groups was compared statistically with the presence of regurgitation symptoms. Based on the data stated above, this study supports the hypothesis that dental plaques may play an important role as a permanent oral resorvoir of H. pylori in transmission route. In addition, dental plaque may be a potential source for reinfection following eradication therapy. However, more profound and comprehensive study using larger number of subjects are required and typing of H. pylori isolates from both the oral cavity and stomach will playa major role 10 studying the modes of transmission Furthermore, the ability to detect H. pylori in dental samples may offer the potential role for a non-invasive test for infection.
