Distribution of Helicobacter pylori and Periodontopathic Bacterial Species in the Oral Cavity.

ABSTRACT: The oral cavity may serve as a reservoir of Helicobacter pylori. However, the factors required for H. pylori colonization are unknown. Here, we analyzed the relationship between the presence of H. pylori in the oral cavity and that of major periodontopathic bacterial species. Nested PCR was performed to detect H. pylori and these bacterial species in specimens of saliva, dental plaque, and dental pulp of 39 subjects. H. pylori was detected in seven dental plaque samples (17.9%), two saliva specimens (5.1%), and one dental pulp (2.6%) specimen. The periodontal pockets around the teeth, from which dental plaque specimens were collected, were significantly deeper in H. pylori-positive than H. pylori-negative subjects (p < 0.05). Furthermore, Porphyromonas gingivalis, a major periodontopathic
