控制牙菌斑对胃炎或消化性溃疡病人胃黏膜幽门螺旋杆菌的影响

Effects of Helicobacter pylori in gastric mucosa of patients with gastritis or peptic ulcer following dental plaque control

目的:研究牙菌斑控制,对胃黏膜幽门螺旋杆菌(HP)检出率的影响,为证实牙菌斑和胃内HP感染具有相关性提供新证据。方法:胃内HP被根除的病人80例,行彻底的牙菌斑控制者为实验组,未行牙菌斑控制者为对照组。半年后以碳13尿素呼气试验确定其胃黏膜HP检出率。结果:试验组胃黏膜中HP的检出率明显低于对照组(P<0.05)。结论:牙菌斑与胃HP感染之间具有明显的相关性。胃炎、消化性溃疡病人应控制牙菌斑。

AIM： By investigating the detected rate of Helicobacter pylori （H. pylori） in the stomach following dental plaque control in patients, to provide new evidence on the correlated relationship of H. pylori between dental plaque and gastric mucosa and clarify the necessily of strategy of dental plaque controlling on those patients. METHODS ： 80 patients with eradicated H. pylori of their gastric mucosa were selected. Dental plaque was controlled completely in the test group. Patients without dental plaque control were assigned in to control group. All patients were conducted by 13C - urea breath test again after half a year to determine the detected rate of H. pylori of their gastric mucosa. RESULTS： Detected rate of H. pylori in the test group was lower significantly than that in the control group （P 〈 0.05 ）. CONCLUSION： There was significant association between dental plaque and gastric H. pylori infection. Dental plaque control procedures should be performed in the treatment of gastritis and peptic ulcer.
