Abstract:

Objective〓〖WTBZ〗To explore the relationship between oral and gastric mucosa helicobacter pylori (H. pylori). 〖WTHZ〗Methods〓〖WTBZ〗108 patients without H. pylori in their gastric mucosa were assigned into the experimental group (n=56) and the control group (n=52). Dental plaque was completely controlled in the experimental group and was not controlled or not successfully controlled in the control group. All patients re-underwent endoscopies after half a year. By endoscopies, biopsies were taken from the gastric mucosa. Histological examination and rapid Urease test were used to determine the presence of H. pylori. 〖WTHZ〗Results〓〖WTBZ〗H. pylori was found in 11 cases (19.6%) in the experimental group and 42 cases (80.8%) in the control group. The presence of H. pylori was significantly lower in the experimental group than that in the control group (P＜0.05). 〖WTHZ〗Conclusion〓〖WTBZ〗There are significant relationships between oral and gastric H. pylori infection, indicating dental plaque should be controlled in treatment of H. pylori-related gastric diseases.

Key words: Dental plaque, Gastric mucosa, Helicobacter pylori, Detection rate
