目的通过调查某医学院校男生齿龈内阿米巴的感染情况,研究齿龈内阿米巴的感染与生活卫生习惯、口腔疾病等影响因素的关系,为进一步防治齿龈内阿米巴感染提供依据。方法 2013年4—7月选取某医学院校部分在校男生共245名进行问卷调查,用一次性消毒牙签取受检者晨起刷牙前齿龈与牙齿之间或病灶表面附着物,口腔内有牙齿排列不齐者取排列不齐的牙齿与该牙龈之间的附着物,口腔内无排列不齐牙齿者随机取齿龈与牙齿之间附着物。检查采用生理盐水直接涂片法。阳性率组间比较采用χ2检验,P<0.05为差异有统计学意义。结果齿龈内阿米巴感染率为29.4%。口腔健康者感染率19.9%,口腔疾病患者感染率43.4%,比较差异有统计学意义(χ2=15.80,P<0.05)。19~22岁感染率36.1%,15~18岁感染率24.1%,比较差异有统计学意义(χ2=4.21,P<0.05)。牙齿排列不齐者感染率24.2%,牙齿排列不齐者感染率37.5%,牙齿排列不齐者感染率较牙齿排列整齐者感染率高(χ2=5.01,P<0.05)。每天刷牙次数≥2次者与每天刷牙次数<2次者的齿龈内阿米巴感染率差异有统计学意义(χ2=6.92,P<0.05);清淡饮食者与辛辣饮食者的齿龈内阿米巴的感染率差异有统计学意义(χ2=4.50,P<0.05);经常嚼口香糖者与不经常嚼口香糖者的感染率差异有统计学意义(χ2=5.43,P<0.05);使用中草药牙膏者与普通防龋牙膏者齿龈内阿米巴感染率差异有统计学意义(χ2=7.61,P<0.05)。吸烟者齿龈内阿米巴感染率与不吸烟者感染率差异有统计学意义(χ2=7.14,P<0.05)。饮酒者齿龈内阿米巴感染率与不饮酒者感染率差异有统计学意义(χ2=4.44,P<0.05)。结论医科院校在校男生齿龈内阿米巴感染普遍,感染与生活习惯和口腔疾病有关。
Objective To investigate the relationship between the infection of Amoeba gingivalis in a medical school boy and the influencing factors such as the habits and habits of oral gingival amoeba and oral diseases and so on and provide the basis for further prevention and cure of the infections of avauginia gingivalis. Methods From April to July 2013, 245 male students from a certain medical school were enrolled in the questionnaire survey. One-time disinfection teeth were used to sign the subjects before the morning brushing teeth between the gums and the teeth or on the surface of the lesion. The teeth in the mouth Misaligned persons to take misaligned teeth and the attachment between the gums, no teeth in the mouth were randomly arranged between the gum and the attachment between the teeth. Check the direct smear method using saline. The positive rate was compared between groups using χ2 test, P <0.05 was considered statistically significant. Results The rate of gingival infection was 29.4%. The infection rate of oral health was 19.9%, and the infection rate of oral diseases was 43.4%, the difference was statistically significant (χ2 = 15.80, P <0.05). The infection rate was 36.1% between 19 and 22 years old and 24.1% between 15 and 18 years old (χ2 = 4.21, P <0.05). Infection rate of missing teeth was 24.2%, infection rate of missing teeth was 37.5%. Infection rate of patients with missing teeth was higher than that with teeth arranged neatly (χ2 = 5.01, P <0.05). There was significant difference in the infection rate of gingival amoebic in those who brushing more than 2 times a day and those who brushing more than twice a day (χ2 = 6.92, P <0.05). In the light dietary and spicy dietary, (Χ2 = 4.50, P <0.05). There was significant difference in infection rates between those who chew chewing gum and those who did not chew gum most often (χ2 = 5.43, P <0.05) There was a significant difference in the infection rate of gingival amoebic with those of ordinary caries-resistant toothpaste (χ2 = 7.61, P <0.05). There was a significant difference in the rates of infection of gingival amoeba among non-smokers and smokers (χ2 = 7.14, P <0.05). There was a significant difference in the rate of gingival amoeba infection among non-drinkers (χ2 = 4.44, P <0.05). Conclusion The prevalence of Entamoeba gingivalis in school medical students is common, and the infection is related to lifestyle and oral diseases.
