Methods Referring to WHO's"Oral Health Surveys Basic Methods"(Fourth Edition)and protocols of the fourth national survey,the method of multistage,stratified,equal capacity,simple random sampling were used to draw a sample of 1419 cases in 12 survey spots in Jiangsu Province,among which 441 5-year-old cases and 978 12-year-old ca-ses respectively. Results The primary tooth caries prevalence in 5-year-old was 71.4% and the mean dmft was 4.05. There was no difference between boys and girls or cities and rural areas(P>0.1). The filling percentage of deciduous teeth was only 2.6%. High-flu-oride region,the frequency of sweet drinks and having sweet foods before sleep were associated with the primary tooth caries. The per-manent tooth caries prevalence in 12-year-old was 33.8% and the mean dmft was 0.60. There was a great significant difference between boys and girls in the proportion of dental caries or in DMFT(P<0.05). The filling percentage of permanent teeth was 15.1%. Gender, the frequency of sweet cakes or cookies and interval of visiting the dentist were associated with the permanent tooth caries. Conclusions The prevalence of children in Jiangsu Province is still high.High-risk groups should be focused on to prevent and control the risk fac-tors of caries,strengthen the oral health education and finally draw up personalized solutions for Jiangsu province.%目的 了解江苏省5岁、12岁青少年儿童龋病流行现状及相关因素,为江苏省龋病防治提供依据.方法 参照WHO《口腔健康调查基本方法》(第4版)和全国第四次口腔健康流行病学调查方案,采用分层,多阶段,等容量随机抽样的方法,抽取江苏省12个调查点共1419名受检者,其中5岁组441人,12岁组978人.结果 5岁组乳牙患龋率和龋均分别为71.4%、4.05,男女、城乡间患龋率、龋均均无明显统计学意义,充填率2.6%;高氟区、甜饮料的进食频率、睡前吃甜食与乳牙患龋有明显的相关性.12岁组恒牙患龋率和龋均分别为33.8%、0.60,女性高于男性且具有明显的统计学差异,城乡间无明显差异,龋齿充填率15.1%;性别、甜点心的进食频率、最近一次看牙间隔时间与恒牙患龋有明显的相关性.结论 江苏省青少年儿童的患龋情况不容乐观,应重点针对高危人群进行防治,控制患龋高危因素,加强口腔健康教育,制定符合江苏省情况的个性化方案.
