摘 要:本实验观察了含氟牙膏对31名4~5岁幼儿氟化物摄入水平的影响。结果发现幼儿使用含氟牙膏2月后尿氟浓度和24小时尿氟排泄量为0.96ppm和0.57mg;使用不含氟牙膏2月后为0.84ppm和0.47mg;统计分析有显著差异(P<0.05)。表明使用含氟牙膏可使幼儿氟摄入量增加。This study observed the influence of fluoride too thpastes on the ingestion of fluoride in 31 children aged 4-5 years. The results demonstrated that the urinary fluoride concentration and the weight of fluoride excreted in urine in 24 hours were 0.96ppm and 0.57mg after the children had used fluoride toothpastes for 2 months. They were 0.84 ppm and 0.47mg after the children had replaced their fluoride toothpastes with non-fluoride ones for 2 months. The differences were statistically significant (P<0.05). It suggests that the intake amount of fluoride increased following the use of fluoride toothpastes by young children.
