在俄罗斯的低氟地区,饮水含氟量0.3mg/L,为预防龋病,1994年已有万余名小儿服用氟化乳。曾有报道,饮水中含氟浓度大于2mg/L时,有20％～30％的小儿出现轻度慢性氟中毒。为研究口服氟化乳的合理性,预防慢性氟中毒,必须监测口服氟化乳小儿氟化物进入机体的水平。已有研究证明,食物和饮水中的氟进入3～6岁小儿机体以后,有50％消耗利用,50％从尿中排出。因此测定尿中氟化物含量,可以计算氟化物进入小儿机体的水平。作者对3个城市的663例口服氟化乳的3～6岁小儿进行监测,在开始口服氟化乳以
In Russia's low-fluoride area, drinking water fluoride 0.3mg / L, to prevent dental caries, in 1994 there are more than 10,000 children taking fluoride milk. It has been reported that drinking water fluoride concentration greater than 2mg / L, 20% to 30% of children with mild chronic fluorosis. In order to study the rationality of oral fluorinated milk and prevent chronic fluorosis, it is necessary to monitor the level of fluoride entering the body of oral fluorinated milk. Research has shown that 50% of fluoride used in food and drinking water enters the body of children aged 3 to 6 years and consumed 50% of the urine. Therefore, the determination of urinary fluoride content, you can calculate the level of fluoride into the body of children. The authors monitored 663 children aged 3-6 years with oral fluoridation in three cities. At the beginning of oral fluoridation,
