在供水含氟量不足的地区(低于0.7ppmF),普遍提倡以氟片或滴剂的形式补充氟化物。常设想规定一种剂量,使每日摄入的氟量相当于氟化供水达1 ppm所得到的氟化物浓度。但是Infante(1975)指出,由生后到二岁每日补充0.5mg氟化物,其结果每日氟的摄入量比从含1 ppm氟供水中所估计摄入的量要大2—6倍。一般认为在儿童期,有规律的服用氟化物具有类似于氟化水的防龋作用。但很少研究斑釉与补充氟化物之间的关系,曾报告在
In areas where the water supply is under-fluorinated (less than 0.7 ppm F), fluoride is generally replenished as fluoride flakes or drops. Standing would like to specify a dose such that the daily intake of fluoride corresponds to the fluoride concentration of 1 ppm of fluoride supplied. However, Infante (1975) noted that daily supplementation of 0.5 mg of fluoride from birth to 2 years of age resulted in 2-6 times greater daily fluoride intake than estimated from 1 ppm fluoride-containing water supply . It is generally believed that regular use of fluoride in childhood has anticaries effects similar to fluorinated water. However, few studies on the relationship between spot glaze and fluoride supplementation have been reported
