目的探讨托幼机构在预防幼儿龋齿中的作用。方法采用队列研究,以2003年入园人群为对照组,以2006年入园人群为干预组实施乳牙龋齿预防的干预措施。经过3a干预,于幼儿毕业离园时体检计算龋齿患病率进行效果比较。结果行为干预组幼儿龋齿患病率增长明显低于对照组的增长速度(对照组54.46%,干预组35.37%,χ2=9.41937,P<0.05)。结论托幼机构是理想的人群干预现场,积极的卫生宣传和行为干预,可以有效减少幼儿乳牙龋齿的发生。

The admission population in 2003 was taken as the control group, and intervention group was enrolled in 2006 as the intervention group for the prevention of deciduous dental caries. After 3a intervention, when the children graduated from the hospital physical examination to calculate the prevalence of dental caries for comparison. Results The prevalence of dental caries was significantly lower in behavioral intervention group than that in control group (54.46% in control group, 35.37% in intervention group, χ2 = 9.41937, P <0.05).
