title: Oral Helicobacter pylori, its relationship to successful eradication of gastric H. pylori and saliva culture confirmation.
abstract: The present study was designed to explore the existence of oral Helicobacter pylori (H. pylori), its relationship in the oral cavity to the success rate of eradication of the gastric H. pylori infection, and to determine if the mouthwash solution contained lysine (0.4%) and glycerol monolaurate (0.2%) (LGM) could eliminate oral H. pylori, as well as using the saliva H. pylori culture to confirm the existence of oral H. pylori. A total of 159 symptomatic individuals with stomach pain and 118 asymptomatic individuals with no stomach complaints, were recruited and tested using the saliva H. pylori antigen test (HPS), the H. pylori flagellin test (HPF), the urea breath test (UBT C(13)) and the polymerase chain reaction (PCR) test, which tests were also confirmed by saliva culture. The test subjects also received various treatments. It was found that the H. pylori antigen exists in the oral cavity in UBT C(13) negative individuals. Traditional treatment for gastric eradication had only a 10.67 percent (10.67%) effectiveness rate on the oral H. pylori infection. In groups of patients with the oral H. pylori infection, but with negative UBT C(13), a mouthwash solution provided a 72.58% effectiveness rate in the 95% of the confidence interval (CI) ranges on the oral H. pylori infection. Traditional drug gastric eradication and teeth cleaning (TC) had less than a 10% effectiveness rate. Treatment of the oral infection increased the success rate of eradication of the stomach infection from 61.33% to 82.26% in the 95% CI ranges. We concluded that the successful rate of eradication of gastric H. pylori bears a significant relationship to the oral infection from H. pylori.
