Abstract: 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.
