The release of fluoride from a glass ionomer cement (ASPA) was compared with that from a silicate cement. Test specimens were shaken in a solution with hydroxyapatite for 7 weeks. The solution was changed every week and the fluoride taken up by the hydroxyapatite measured. The specimens released considerably more fluoride during each of the first 2 weeks than during each of the subsequent 5 weeks. The continued release did not decrease very much with time. Slightly more fluoride was released from the glass ionomer cement than from the silicate.
将玻璃离子水门汀（ASPA）的氟释放量与硅酸盐水泥的氟释放量进行了比较。测试样本在含有羟基磷灰石的溶液中振荡7周。每周更换溶液，并测量羟基磷灰石吸收的氟。在最初2周的每一周里，样本释放的氟都比随后5周的每一周要多得多。随着时间的推移，持续释放量并没有大幅下降。玻璃离子水门汀释放的氟略多于硅酸盐水泥。
