本研究检查了四种修复材料在用 APF 或中性氟化物凝胶处理一分钟或四分钟后氟化物释放和补充的差异。将样品浸入 2 mL 去离子水中，同时使用离子选择性电极和分析仪每隔 24 小时测量氟化物释放量，持续 15 天。然后用氟化物凝胶处理材料。测量氟化物释放15天。方差分析 (p0.05)，Ketac-Fil 除外。与树脂材料的 APF 凝胶相比，凝胶应用前后的释放模式相似，并且在第 16 天时释放量高于第一天，与 Fuji 11 LC 和 Vitremer 的初始释放量相比，在第 15 天释放量更高。 Et 得出结论，在应用 APF 凝胶四分钟后，RM-GIC 是释放氟化物最有效的材料。
This study examined the differences in fluoride release and recharge among four restorative materials following treatment with APF or neutral fluoride gel for one or four minutes. Specimens were immersed in 2 mL of deionized water, while fluoride release was measured at 24-hour intervals for 15 days using an ion-selective electrode and analyzer. The materials were then treated with the fluoride gels. The fluoride release was measured for 15 days. ANOVA (p0.05), except for Ketac-Fil. The pattern of release before and after application of the gels was similar and was higher at day 16 compared to day one for the APF gel for resin materials, with higher release at day 15 compared to the initial for Fuji 11 LC and Vitremer. Et was concluded that RM-GICs were the most effective materials with regards to fluoride release after application of APF gel for four minutes.
