The enamel solubility reducing characteristics of four fluorides -- sodium fluoride (NaF), acidulated phosphate fluoride (APF), stannous fluoride (SnF2), and sodium monofluorophosphate (Na2PO3F), each prepared to contain 1.23 per cent F are evaluated. Initial solubility reduction by SnF2, 81.7 per cent was significantly (P less than .01) higher than that of 76.9 per cent provided by APF, however, after repeated exposure to acid etches the protection by APF became significantly (P less than .01) higher than that derived from SnF2. The durability of protection provided by SnF2 after overnight washing, was significantly (P less than .01) higher than that of APF. Results for NaF and MFP were significantly (P less than .01) lower than those of either APF or SnF2 at any point in the experiment.
对四种氟化物——氟化钠（NaF）、酸性磷酸氟（APF）、氟化亚锡（SnF₂）和单氟磷酸钠（Na₂PO₃F）的牙釉质溶解度降低特性进行了评估，每种氟化物均制备成含1.23%的氟。氟化亚锡使初始溶解度降低81.7%，显著（P小于0.01）高于酸性磷酸氟提供的76.9%；然而，在反复暴露于酸蚀后，酸性磷酸氟提供的保护显著（P小于0.01）高于氟化亚锡。过夜冲洗后，氟化亚锡提供的保护耐久性显著（P小于0.01）高于酸性磷酸氟。在实验的任何时间点，氟化钠和单氟磷酸钠的结果均显著（P小于0.01）低于酸性磷酸氟或氟化亚锡。
