The aim of the study was to investigate the relationship between halitosis and Helicobacter pylori infection in stomach.
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.
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).
H.pylori in stomach may be involved in the presence of halitosis in periodontal healthy subjects.
本研究旨在探讨口臭与胃内幽门螺杆菌感染之间的关系。
纳入50名无牙周疾病和系统性疾病（排除胃肠道疾病）的受试者。通过活检和碳-14尿素呼气试验诊断幽门螺杆菌感染。使用SPSS11.5软件包分析数据。
根据牙周指数，所有受试者牙周健康。口臭受试者中幽门螺杆菌感染率显著高于正常受试者（57.1%对18.2%，P<0.01）。Logistic回归分析显示幽门螺杆菌是方程中唯一的显著变量（P<0.05）。
胃内幽门螺杆菌可能与牙周健康受试者口臭的存在有关。
