Human enamel specimens were topically treated in vitro, using either a clear, aged aqueous mixture consisting of SnF2 and amine fluoride 297, or SnF2 alone, amine fluoride 297 alone, NaF, or water (as the negative control). The fluoride concentrations used were 250 ppm F1/n. The topically treated enamel specimens were then acid-etched for 5, 10, 15, and 15 seconds, respectively, in 2NHC1. The amount of phosphorous dissolved from the enamel and the depth of etch were both significantly less for the groups treated with SnF2/AmF297 and SnF2 alone, which indicated better protection against acid dissolution than the other three groups.
人牙釉质标本在体外进行局部处理，使用一种由氟化亚锡和297胺氟化物组成的澄清、老化的水性混合物，或单独使用氟化亚锡、单独使用297胺氟化物、氟化钠或水（作为阴性对照）。所使用的氟化物浓度为250 ppm F1/n。然后将经局部处理的牙釉质标本分别在2N盐酸中酸蚀5、10、15和15秒。用氟化亚锡/297胺氟化物和单独使用氟化亚锡处理的组，从牙釉质中溶解的磷量和蚀刻深度均显著较低，这表明它们比其他三组对酸溶解具有更好的保护作用。
