深圳市宝安城区学龄前儿童使用氟化物预防龋病的监测报告

Monitoring analysis on dental caries prophylaxis using fluorides among preschool children in Bao'an District,Shenzhen

目的:评估学龄前儿童使用氟化物预防龋病的效果。方法:2005～2009年间,对宝安城区幼儿园使用氟化物情况进行监测,分析氟化物预防龋病的效果。结果:5年间共监测46279例学龄前儿童,有40851例使用了氟化物预防龋病,使用率88.27%。含氟漱口水的使用率为91.28%,误吞率5.63%;含氟凝胶使用率81.28%,误吞率3.17%;氟化泡沫使用率95.33%,误吞率1.10%;不同氟化物使用率和误吞率的差异有统计学意义(P=0.000)。患龋率从2005年的76.19%下降到2009年的45.91%;龋均从2005年的6.11颗下降到2009年的3.07颗;不同年份间患龋率的差异有统计学意义(P=0.000)。结论:2005～2009年宝安城区学龄前儿童氟化物预防龋病项目取得了肯定的成效,氟化物可以有效降低龋齿的发生率。

Objective：The aim is to investigate the usage of fluorides among preschool children in Bao＇an District,Shenzhen（2005 ～2009） and evaluate the effect of fluorides on dental caries prophylaxis used by preschool children.Method：In the period of 2005～2009,the usage of fluorides in kindergartens in Bao＇an District was monitored,combining with the semiannual oral health examination and collecting information on fluoride usage and oral health of preschool children to analyze the effect of fluorides on dental caries prophylaxis.Result：During the 5 years,a total of 46279 cases of preschool children were monitored,wherein fluorides were used in 40851 cases,and the usage rate is calculated as 88.27 %.The usage rates of fluorine-containing mouth-washing,fluorine-containing gel and fluorinated foam are 91.28 %,81.28 % and 95.33 %,respectively;the respective swallowing rates for the 3 different fluorides are 5.63 %,3.17 % and 1.10 %.The differences between usage rates and swallowing rates of different fluorides showed statistical significance（x2=1643.01,P = 0.000;x2=403.66,P =0.000）.Caries prevalence rate has dropped from 76.19 % in 2005 to 45.91 % in 2009;caries have dropped from 6.11 in 2005 to 3.07 in 2009;The differences between caries prevalence rates of different years showed statistical significance（x2=2416.58,P =0.000）.Conclusion：Positive results have been achieved through dental caries prophylaxis project for preschool children in Bao＇an District during 2005～2009,and fluorides can potently decrease the incidence of dental caries.
