| 摘 要： | 目的：了解氟化泡沫在人体的排泄规律，为氟化泡沫应用于群防群治提供理论依据。方法：应用氟离子选择性电极测定学龄前儿童使用氟化泡沫后30分、2h、4h,6h,2d,3d,4d,5d尿氟浓度的变化。结果：使用氟化泡沫后，2h尿氟浓度增加，直到用后3d，且与使用前及对照组差异有显著性（P＜0．01）；4d,5d无差异（P＞0．05）。结论：使用氟化泡沫后，氟的摄入量小于每日总氟适宜摄入量及每日慢性中毒量，氟化泡沫使用是安全的。

| Abstract: | To demonstrate the law of excreting after taking fluoride foam.To provide the theoretic basis for dental caries prevention. With fluoride ion selective electrode the fluoride concentrations were measured after 30min,2h,4h,6h,2d,3d,4d,5d in urine of pre school students. Urine fluoride concentrations rose after 2h to 3ds with fluoride foam.There were significant difference between test and control group( P <0.01).No difference were found between test and control group( P >0.05) after 4d,5d. Conclusion] It was safe to use fluoride foam when fluorid foam concentration was lower than total dose in need and chronic toxic dose. |
