牙斑幽门螺杆菌与慢性胃炎之间的关系

目的研究牙斑幽门螺杆菌与慢性胃炎之间的关系。方法对胃炎组、胃炎治疗组分别进行牙斑和胃黏膜幽门螺杆菌培养和比较。结果牙斑细菌培养：胃炎组阳性14例，阳性率为12．8％；治疗组阳性11例，阳性率为10．1％。胃黏膜细菌培养：胃炎组阳性47例，阳性率为43．1％；治疗组阳性19例，阳性率为17．4％。治疗前后比较牙斑标本差异无显著性（P〉0．05），胃黏膜标本差异有非常显著性（P〈0．001）。结论牙斑中确实存在着幽门螺杆菌，而且是胃内反复感染的源泉，以致慢性胃病反复发作，难以治愈。

Helicobacter pylori in dental plaque and its relevance to chronic gastritis

Objective To study Helicobacter pylori(H.pylori) in dental plaque and its relevance to chronic gastritis.Method To compare to chronic gastritis group and treatment group,dental plaque and gastric biopsy samples were respectively collected for detection of H.pylori by in vitro culture.Results Dental plaque samples culture:chronic gastritis group positive rate was 12.8%;treatment group positive rate was 10.1%(P>0.05).Gastric biopsy samples cultrue:chroic gastritis group positive rate was 43.1%;traetment group positive rate was 17.4%(P<0.001).Conclusions This study shows that H.pylori exists really in dental plaque and it is related to chronic gastritis.Dental plaque H.pylori lead to chronic gastritis breakig out again and again,furthermore hard to cure.
