Helicobacter pylori (Hp) were detected in the dental plaque in 40 patients with peptic ulcer, chronic gastritis or gastric cancer with rapid urease test, anti-Hp fluorescein-labelled antibody staining, bacterial culture and electronic microscopy. At the same time, biopsy specimens from the gastric antrum of these patients were studied with WS staining and rapid urease test to detect Hp. The results show that a great lot of Hps is present in most of the patients' dental plaque. The morphological, biochemical and immunological characteristics of the Hp in the dental plaque are similar to those Hp in the gastric mucosa. The above results reveal that the Hp in the dental plaque may be identical with those in the stomach.
采用快速尿素酶试验、抗幽门螺杆菌荧光素标记抗体染色、细菌培养及电子显微镜检查，对40例消化性溃疡、慢性胃炎或胃癌患者的牙菌斑进行幽门螺杆菌（Hp）检测。同时，对这些患者的胃窦活检标本进行WS染色和快速尿素酶试验以检测Hp。结果显示，大多数患者的牙菌斑中存在大量Hp。牙菌斑中Hp的形态、生化和免疫学特征与胃黏膜中的Hp相似。上述结果表明，牙菌斑中的Hp可能与胃中的Hp相同。
