在一些地区居民供给的水缺乏氟,美国牙科协会牙齿治疗委员会推荐对儿童食物补充氟化物是一种安全有效的防龋措施,它可获得与同一时期应用氟化饮水一样的效果。补充之前必须确定儿童饮水自然氟浓度。自然氟大于0.2ppm,建议不补充以免儿童牙齿钙化时氟的摄取过量产生氟中毒。自然氟少于0.2ppm,2岁以下儿童,1片含氟化物1mg的片剂应加1.14公升水饮用或制备成食物及配方,每天服0.25 mg氟化物,2—3岁儿童每天0.5mg,3岁以上每天应服1.0mg。近来,Wei和他的同事设计的氟化物补充表在美国受到普遍的注意,对饮水氟少于0.2ppm地区,他们规定儿童头6个月不补
Fluoride is not available in some areas to residents, and dental care councils recommended by the American Dental Association that supplementation of fluoride with children's food is a safe and effective measure to prevent dental caries and achieve the same benefits as fluorinated drinking water during the same period. Children's drinking water must be determined before adding fluoride natural fluorine concentration. Natural fluoride is greater than 0.2ppm, it is recommended not to prevent fluoride in children with excessive calcium fluoride intake of fluoride poisoning. Natural fluoride less than 0.2ppm, children under 2 years old, 1 tablet containing fluoride 1mg should be added 1.14 liters of water drinking or prepared into food and formula, 0.25 mg per day fluoride, 2-3-year-old children 0.5mg daily, 3 years old should be served 1.0mg daily. Recently, fluoride supplements designed by Wei and colleagues have received widespread attention in the United States. For fluoride less than 0.2 ppm in drinking water, they provide that children do not make up the first 6 months
