The article below shows that H. Pilori is found in dental plaque. H. Pilori is the bacteria that causes Stomach Ulcers.

AIM: To establish whether virulence factor genes vacA and cagA are present
in Helicobacter pylori (H. pylori) retrieved from gastric mucosa and dental
plaque in patients with dyspepsia. METHODS: Cumulative dental plaque
specimens and gastric biopsies were submitted to histological examination,
rapid urease test and polymerase chain reaction (PCR) assays to detect the
presence of cagA and vacA polymorphisms. RESULTS: Detection of H. pylori
from dental plaque and gastric biopsy samples was greater by PCR compared to
histological examination and the rapid urease test. DNA from H. pylori was
detected in 96% of gastric mucosa samples and in 72% of dental plaque
samples. Sixty-three (89%) of 71 dental plaque samples that were H.
pylori-positive also exhibited identical vacA and cagA genotypes in gastric
mucosa. The most common genotype was vacAs1bm1 and cagA positive, either in
dental plaque or gastric mucosa. These virulent H. pylori isolates were
involved in the severity of clinical outcome. CONCLUSION: These pathogenic
strains were found simultaneously in dental plaque and gastric mucosa, which
suggests that gastric infection is correlated with the presence of H. pylori
in the mouth.
