Liberation of stannous fluoride incorporated in the alloy powder before amalgamation was demonstrated for all the amalgams tested in this study. This liberation was observed for stannous fluoride concentrations of 0.5% and 1%. Clear differences were noted in relation to the type of amalgam studied. Through the use of a non destructive method (activation with charged particles) it was possible to measure the fluoride concentration in enamel before and after the contact with the fluoridated amalgam. This analysis demonstrated that the fluoride liberated from the amalgam was trapped by enamel in contact with alloys containing 0.5% or 1% of stannous fluoride. The enrichment in fluoride was very important in the first weeks and remained high after four months. No significant difference appeared between alloys fluoridated at 0.5% and 1%. The dissolution of calcium fluoride through a KOH treatment showed that the amount of stable fluoride (fluorapatite) formed was important.
在本研究中测试的所有汞合金中，均证实了在汞齐化之前合金粉末中所含氟化亚锡的释放。在氟化亚锡浓度为0.5%和1%时观察到了这种释放。在所研究的汞合金类型方面发现了明显差异。通过使用一种非破坏性方法（带电粒子活化），可以测量与含氟汞合金接触前后牙釉质中的氟浓度。该分析表明，从汞合金中释放的氟被与含0.5%或1%氟化亚锡的合金接触的牙釉质所捕获。在最初几周内氟的富集非常重要，四个月后仍保持在较高水平。氟化亚锡含量为0.5%和1%的合金之间未出现显著差异。通过氢氧化钾处理氟化钙的溶解表明，形成的稳定氟（氟磷灰石）的量很重要。
