Outline of Final Research Achievements

Helicobacter pylori infection is believed to be acquired in early childhood, mainly via the oral cavity. However, the route of infection has yet to be elucidated. In the present study, we constructed a novel PCR system for the identification of H. pylori DNA based on complete genome information of 48 H. pylori strains registered in a database. Analysis of infected root canal specimens using this system revealed a detection rate of 15%, indicating the root canal as a possible reservoir for H. pylori.
