摘要
目的:分析甘肃省12岁儿童恒牙龋病及其相关因素,为卫生行政部门制订相关政策提供依据。方法:按照第三次全国口腔健康流行病学调查标准和方法,采用多阶段分层等容量随机抽样方法,对甘肃省791名12岁儿童进行了龋病流行病学调查及其相关因素问卷调查,并与1995年第二次全国口腔健康流行病学调查甘肃省12岁儿童的恒牙患龋情况进行比较。结果:甘肃省12岁儿童的恒牙患龋率、龋均分别为19.09%、0.32,城市高于农村(P=0.032,P=0.017),龋牙充填率10.80%,窝沟封闭率0.76%;城市儿童进食甜点、糖果或巧克力、碳酸饮料、加糖果汁的频率明显高于农村(P<0.05),56.4%的儿童每天只刷牙1次,26.9%儿童不是每天都刷牙,刷牙情况城市儿童好于农村儿童(P=0.000)。结论:甘肃省12岁儿童恒牙患龋率和龋均呈现下降趋势,口腔健康状况有了明显改善,但窝沟封闭率和恒牙龋牙充填率很低,口腔基本保健行为不够理想,应加强对窝沟封闭和龋牙充填重要性的宣传教育,使学龄儿童特别是农村学龄儿童,养成良好的口腔卫生习惯,做好早期口腔保健预防措施,降低学龄儿童患龋率。
AIM：To analyze dental caries and risk factors among 12 year old children in Gansu province,in order to provide some evidences for enacting the policy of the hygiene administrative department.METHODS：Based on the Third National Oral Health Epidemiological Survey,an equal-sized stratified multi-stage random sampling design was applied in the investigation.A total of 791 twelve year old children were included in the investigation.All examinees answered an oral health knowledge questionnaire and were examined by experienced dentists.RESULTS：The average caries prevalence rate and DMFT was 19.09% and 0.32.Urban children showed higher prevalence rate and DMFT than the children in countryside（P = 0.032,P = 0.017）.The average dental caries filling rate was 10.80%,pit-and-fissure sealing rate was 0.76%.The urban children had a higher frequency of taking sugar-containing foods and drinks than countryside children（P 〈 0.05）.56.4% of the children brush their teeth only once daily.26.9% of the children do not brush their teeth everyday.Children in the city had more frequent usage of toothbrush than children in the countryside（P = 0.000）.CONCLUSION：More active oral health measures,especially oral health education,should be taken to improve the oral health of children.
