<I>Helicobacter pylori</I> is an important pathogen involved in the development of gastrointestinal ulcers, but its involvement in oral ulcerous lesions is unclear. As culture is generally recognized as the gold standard for diagnosis of <I>H. pylori</I> infection, we employed this approach to assess the association of <I>H. pylori</I> with oral mucosal ulcerations. Samples were collected from patients with oral mucosal ulcerative disorders : 12 cases of recurrent aphthous stomatitis (RAS), 7 cases of herpes simplex virus (HSV) stomatitis, and 3 cases of erosive lichen planus (LP). Serum IgG antibodies against <I>H. pylori</I> were examined in all cases. All of the RAS and erosive LP cases were culturenegative for <I>H. pylori</I>, while two cases of HSV stomatitis were positive. The two culture-positive cases were also seropositve for the <I>H. pylori</I> antigen. It is suggested that <I>H. pylori</I> might not have a direct association with oral ulcerations. However, <I>H. pylori</I> in the oral cavity might exist in a non-culturable coccoid state without productive infection, and might form colonies only under special conditions such as HSV infection.
