【摘要】：目的了解我国东部地区儿童3~5岁期间乳牙龋病的流行现况和变化趋势,为改善儿童口腔健康提供科学依据。方法采用多阶段分层整群抽样方法,抽取我国东部地区北京、上海、广东三省(市)2010年新入园的3岁儿童建立了乳牙龋病监测队列(n=896),连续3年检查队列儿童牙齿状况。结果本队列随访率为79.8%(n=715)。715名儿童3岁、4岁、5岁时患龋率分别为41.4%、55.0%、63.9%,患龋率逐年增加(Z=-8.535,P0.05);龋均分别为1.76、2.54、3.31,年均增加0.78颗(F=33.886,P0.05),每年的显著性龋均指数(significant caries indices,SiC)分别是当年整体龋均的2.9倍、2.6倍、2.4倍。3~4岁、4~5岁龋齿年发病率分别为43.6%、46.9%,2年累积发病率为62.7%。农村儿童累积发病率大于城市儿童(P0.05),基线患龋儿童2年累积发病率大于无龋儿童(P0.05)。上颌中切牙、下颌乳磨牙的患病率和发病率均较高。结论东部地区儿童3~5岁期间患龋率高,发病率高,一级预防应从喂养早期开始;应针对无龋儿童、高患龋水平区域、高患龋水平个体、好发牙位进行综合防治。
[Abstract]:Objective to investigate the prevalence and trend of deciduous dental caries in children aged 3 to 5 years in eastern China, and to provide a scientific basis for improving children's oral health. Methods the multistage stratified cluster sampling method was used to select Beijing and Shanghai in the eastern part of China. In 2010, three provinces (cities) of Guangdong established a primary dental caries monitoring cohort 896 to check the tooth status of the children in the cohort. Results the follow-up rate of this cohort was 79.8%, 7155.715 children aged 3 years, 4 years old and 5 years old, the prevalence rate of caries was 41.4 55.0% and 63.9%, respectively. The incidence rate of caries increased year by year, the average caries were 1.762.544 / 3.31, the average annual increase was 0.78 FG 33.886N / P 0.05, and the significant caries indicessil (sic) was 2.9 times of that of the whole caries in the year. The annual incidence of caries in 4years old was 43.66.9. the cumulative incidence of caries in 4years was 46.90.The annual incidence of caries was 2.9-fold of that of the whole caries of the whole year. The incidence of caries in 4years of age was 43.66.9. the cumulative incidence rate of caries was 46.9in the year as a whole, and the cumulative incidence of caries in each year was 2.9-times that of the whole caries. The cumulative incidence rate of rural children was higher than that of urban children (P 0.05), and that of baseline children with caries was higher than that of children without caries (P 0.05). Conclusion the prevalence rate of dental caries in children in the eastern region is high and the incidence rate is high. The primary prevention should begin at the early stage of feeding, and should be aimed at the areas with high caries level and the individuals with high caries level in the areas without caries. The predilection teeth were treated with comprehensive prevention and treatment.
