目的考察六种玻璃离子水门汀(G1C)样本在蒸馏水及人工唾液中的氟释放行为.方法在蒸馏水和人工口腔的氟释放采用气象色谱进行测量.结果各种GIC材料在调和开始时氟释放速度最大；随后急剧减低,经过56 d后氟释放量虽然呈减少倾向,但仍能够长期持续释放.编号3、5、6号材料在人工唾液中氟释放量明显低于蒸馏水,编号1、2号材料在两种介质中氟释放量没有区别,而编号4号材料在人工唾液中氟释放量高于蒸馏水.GIC固化体浸入介质时间与其释放累积氟量符合log(Y) =a+b×log(t)关系式.结论 GIC样本在蒸馏水及人工唾液中的氟释放累积量与浸入时间符合对数关系.

Objective In this study,the fluorine release behavior of six glass ionomer cements (GIC) samples was investigated in distilled water and artificial saliva.Methods The fluorine release behavior in GIC was measured by gas chromatography.Results Various GIC materials had the maxium fluorine release rate in the beginning,and the rate decreased rapidly.After 56 days,although the fluorine release quantity was in a trend of decreasing,the release process can be retained during a long period.For No3,No5,and No6 sampler,the fluorine release quantity in artificial saliva was lower than distilled water,whereas no significant difference was observed for Nol and No2 materials.The No4 sample produced a larger fluorine release quantity in artificial saliva.It can also be conducted that the immersible time of GIC and the fluorine release quantity met the equation of log ( Y ) =a + b x log ( t ).Conclusion The fluorine release behavior of six GIC matched the logarithmic regulation.
