The aim of this study was to determine the contributions of sealant and water fluoridation to the time trends in dental caries from 2003 to 2010.
Data were from three waves of the Korean National Oral Health Surveys between 2003 and 2010, including a total of 23 059 children (11 889 boys and 11 170 girls) aged 8, 10, and 12 years. The impacts of sealant and water fluoridation on dental caries were obtained by logistic regression for each age group of children. The contributions of sealant and water fluoridation to the time trends in the prevalence of dental caries were examined by a series of logistic regression models, and changes in the adjusted odds ratios for each survey year were also calculated.
Over the past 7 years, the prevalence of dental caries decreased dramatically. Although sealant had a significant impact on dental caries in each survey year, remarkable decreases in dental caries from 2003 to 2010 were not explained by the secular changes in the dental sealant or water fluoridation factor.
We observed important population declines in dental caries in Korea in children aged 8-12 years; however, the likely causes for these secular trends remain to be determined.
本研究旨在确定窝沟封闭剂和水氟化作用对2003年至2010年龋齿发病时间趋势的影响。
数据来自2003年至2010年韩国全国口腔健康调查的三个阶段，共纳入23059名8岁、10岁和12岁的儿童（11889名男孩和11170名女孩）。通过对各年龄组儿童进行逻辑回归分析，得出窝沟封闭剂和水氟化作用对龋齿的影响。通过一系列逻辑回归模型研究窝沟封闭剂和水氟化作用对龋齿患病率时间趋势的影响，并计算各调查年份调整后的比值比变化。
在过去7年中，龋齿患病率显著下降。尽管窝沟封闭剂在各调查年份对龋齿都有显著影响，但2003年至2010年龋齿患病率的显著下降并不能用窝沟封闭剂或水氟化作用因素的长期变化来解释。
我们观察到韩国8至12岁儿童的龋齿患病率显著下降；然而，这些长期趋势的可能原因仍有待确定。
