The objective of this study was to evaluate the fluoride release from three different types of glass ionomer cements and the fluoride release after exposure to NaF solution and APF gel. After determining the fluoride release during 28 days in artificial saliva, specimens were divided into two groups and exposed to NaF solution and APF gel for 2 min during 20 days. For each material, the release was highest during the first day, but Kromoglass released statistically significantly higher amounts of fluoride than the other. Vitrabond and Dyract followed in order. The differences in all groups were not statistically significant after third day. For statistical analysis: Paired- T Test, Variance Analysis and Duncan's Multiple Range Test were used. After exposure to NaF solution and APF gel all glass ionomer cements were recharged but the specimens exposed to APF gel were statistically significantly more recharged than NaF solution. As a result we conclude that glass ionomer cements can act as a rechargeable slow fluoride release systems and especially in caries active children, topical NaF applications with glass ionomer cements could be recommended as a preventive measure. We conclude that these results should be supported with long term and in vivo studies.
本研究的目的是评估三种不同类型的玻璃离子水门汀的氟释放情况，以及暴露于氟化钠溶液和酸性磷酸氟凝胶后的氟释放情况。在测定人工唾液中28天的氟释放量后，将标本分为两组，在20天内暴露于氟化钠溶液和酸性磷酸氟凝胶中2分钟。对于每种材料，第一天的释放量最高，但Kromoglass释放的氟量在统计学上显著高于其他材料。Vitrabond和Dyract依次次之。第三天后，所有组的差异均无统计学意义。进行统计分析时，使用了配对t检验、方差分析和邓肯多重极差检验。暴露于氟化钠溶液和酸性磷酸氟凝胶后，所有玻璃离子水门汀都得到了再充电，但暴露于酸性磷酸氟凝胶中的标本在统计学上比暴露于氟化钠溶液中的标本再充电程度显著更高。因此，我们得出结论，玻璃离子水门汀可以作为可再充电的缓慢氟释放系统，特别是对于患龋活跃的儿童，推荐使用玻璃离子水门汀进行局部氟化钠应用作为一种预防措施。我们得出结论，这些结果应通过长期和体内研究来支持。
