One hundred thirty-three farm worker children with an average age of 17 months participated in a study of a fluoride varnish in WIC programs in the Yakima Valley of Central Washington. After parents were interviewed, the child was examined and a fluoride varnish applied to the maxillary incisors. At the six-month recall 62 children and their parents returned. Results indicated a significant decrease in decalcification from 35 percent to 21 percent and an increase in decay from 3 percent to 16 percent. The rate of decay was lower than the 30 percent found in this age-group in this population. Of 130 sound teeth at baseline, 13 percent were decayed or decalcified in six months; of 73 decalcified teeth at baseline, 51 percent were found to be sound in six months. Additional experimentation with fluoride varnish is warranted.
133名平均年龄为17个月的农场工人子女参与了华盛顿州中部亚基马山谷妇女、婴儿和儿童营养补充计划（WIC）中一项关于含氟涂料的研究。在对家长进行访谈后，对孩子进行了检查，并在上颌切牙上涂抹了含氟涂料。在六个月的回访中，62名儿童及其家长返回。结果显示，脱矿率从35%显著降至21%，龋齿率从3%升至16%。该年龄段人群的龋齿率低于30%。在基线时的130颗健全牙齿中，13%在六个月内出现龋齿或脱矿；在基线时的73颗脱矿牙齿中，51%在六个月后被发现恢复健全。有必要对含氟涂料进行进一步试验。
