Effect of dental plaque control on infection of Helicobacter pylori in gastric mucosa.
BACKGROUND
Data on the role of dental plaque in the transmission of Helicobacter pylori have varied. Furthermore, there has been few reports on the relationship between dental plaque control and H. pylori infection of gastric mucosa. The purpose of this study was to elucidate this potential relationship.


METHODS
The (13)C urea breath test was conducted on 56 subjects who received dental plaque control and 51 subjects who did not.


RESULTS
The prevalence of H. pylori in the gastric mucosa was 19.64% in patients who received dental plaque control, which was significantly lower than in those without dental plaque control (84.31%).


CONCLUSIONS
Long-term professional dental plaque control was associated with less gastric reinfection by H. pylori, suggesting that dental plaque control may help to prevent H. pylori-induced gastric disease or reinfection.
