An epidemiological investigation of caries status in 8-year-old children in Jiangsu Province

目的了解江苏省8岁儿童龋病流行状况,为开展儿童口腔卫生保健提供基线资料,为制定防龋措施提供参考依据。方法采用分层、随机抽样的方法,抽取江苏省13个省辖市的市区和19个县级市共4 416名8岁儿童。结果恒牙患龋率和龋均分别为17.50%和0.33,县级市儿童显著高于省辖市市区,女性显著高于男性;乳牙患龋率和龋均分别为64.08%和2.35,县级市儿童显著高于省辖市市区,男女间无显著差异。恒牙充填率为4.37%,乳牙充填率为5.21%,省辖市市区儿童显著高于县级市。结论江苏省8岁儿童乳恒牙患龋率均较高且充填率较低,应加强儿童口腔健康教育,提高儿童、家长和教师的口腔健康知识,采取有效的龋病防治措施,才能有效降低患龋率,提高儿童口腔健康水平。
