Conventional glass ionomer cements are known to release fluoride ions to the surroundings. Recently, resin-modified glass ionomer cements have been produced. These have differing chemical formulations and this may affect their ability to release fluoride ions. The study evaluates both the fluoride release and compressive strength of one conventional and four resin-modified glass ionomer cements with respect to time. The results showed that the formulation of the resin-modified materials influenced the fluoride release. One resin-modified glass ionomer (PhotacFil) released more fluoride than all other materials, while Vitremer, Fuji II LC and Chemfil Superior release similar amounts. Variglass had a very much smaller elution of fluoride ions. This suggests that there is considerable variation in fluoride release between materials of similar generic origin. The compressive strength of these materials was not affected with time.
传统玻璃离子水门汀会向周围环境释放氟离子。近来，已生产出树脂改性玻璃离子水门汀。这些材料具有不同的化学配方，这可能会影响它们释放氟离子的能力。该研究评估了一种传统玻璃离子水门汀和四种树脂改性玻璃离子水门汀在不同时间的氟释放量和抗压强度。结果表明，树脂改性材料的配方会影响氟释放。一种树脂改性玻璃离子水门汀（PhotacFil）释放的氟比所有其他材料都多，而Vitremer、Fuji II LC和Chemfil Superior释放的氟量相似。Variglass的氟离子洗脱量非常小。这表明，同类材料之间的氟释放存在很大差异。这些材料的抗压强度不受时间影响。
