[The relationship of halitosis and Helicobacter pylori].
OBJECTIVE
The aim of the study was to investigate the relationship between halitosis and Helicobacter pylori infection in stomach.


METHODS
Fifty subjects without periodontal diseases and systematic disease (exclude gastrointestinal diseases) were included. Infection of H.pylori was diagnosed by biopsy and (14)C-urea breath test. SPSS11.5 software package was used to analyze the data.


RESULTS
All the subjects were periodontal healthy according to the periodontal index. The prevalence of H.pylori infection in halitosis subjects was significantly higher than that in the normal subjects (57.1% VS 18.2%, P<0.01). Logistic regression analysis showed that H.pylori was the only significant variable in the equation(P<0.05).


CONCLUSIONS
H.pylori in stomach may be involved in the presence of halitosis in periodontal healthy subjects.
