目的了解唐山市人群齿龈内阿米巴感染情况。方法选择唐山市路北区防疫站和滦县人民医院体检者400人,用无菌牙签取齿龈周围垢物或口腔病灶垢物,采用生理盐水直接涂片法光镜下检查齿龈内阿米巴,记录观察结果。结果受检者齿龈内阿米巴感染率为27.50%(110/400),其中低文化程度者感染率高于高文化程度者(χ2=50.00,P<0.05),不经常刷牙者感染率高于经常刷牙者(χ2=36.02,P<0.05),使用药物牙膏者感染率高于使用普通牙膏者(χ2=4.88,P<0.05),吸烟及饮酒者感染率高于不吸烟和不饮酒者(χ2吸烟=35.62,χ2饮酒=33.57,P均<0.05),有口腔疾病患者感染率高于健康者(χ2=50.73%,P<0.05)。在各种口腔疾病中,牙周炎患者齿龈内阿米巴感染率最高,为56.52%。结论唐山市人群中齿龈内阿米巴感染较普遍,齿龈内阿米巴感染与口腔疾病具有相关性。
Objective To understand the infection of Entamoeba giaceae in Tangshan population. Methods 400 people from the Lubei District Epidemic Prevention Station and the Luanxian People’s Hospital of Tangshan City were enrolled in the study. Aseptic toothpicks were used to pick out the dirt around the gingival or oral lesion. Direct smear with saline was used to examine the gingivitis a. , Record the observation results. Results Infection rate of the infected patients was 27.50% (110/400), among them, the infection rate of the lower education level was higher than that of the higher education level (χ2 = 50.00, P <0.05), and the rate of infrequent brushing was high In regular brushing patients (χ2 = 36.02, P <0.05), the prevalence of using drug toothpaste was higher than that of patients with common toothpaste (χ2 = 4.88, P <0.05). The prevalence of smoking among smokers and drinkers was higher than that of non-smoker and non-drinkers (χ2 = 35.62, χ2 = 33.57, P <0.05). The prevalence of oral diseases was higher than that of healthy subjects (χ2 = 50.73%, P <0.05). In a variety of oral diseases, patients with periodontitis have the highest prevalence of gingival infection, 56.52%. Conclusion The prevalence of amoebic gingival infection in Tangshan population is more common. The infection of the gingival amoeba is related to oral diseases.
