已经确定玻璃离聚物（GI）释放氟化物（F）。F释放的程度取决于产品的物理和化学性质。在本研究中，对五种不同品牌的氟化物释放和GI再充氟化物的能力进行了测试：XR Iceland（Kerr）、Vitrebond（3M）、GC Fuji Lining（G.C.牙科工业公司），基线VLC（Dentsply）和Zinomer（Dent. Mat.）。为每个品牌制备15个试样。将试样浸入去离子水中。每天测量一次释放的F，持续11天。在第11、16、21和26天，用0.02%、0.04%和0.2% NaF溶液对供试品进行再氟化5分钟。每天测量从再充电样本释放的F，直到第32天。胃肠道中的氟含量与释放氟的能力呈正相关。在溶液中反复暴露于F后，五种材料被F“重新充电”，0.2%的溶液是最有效的。XR离聚物比任何其他材料释放更多的氟化物，并显示出最大的再充电能力。Zinomer释放的氟化物明显少于任何其他材料，并且显示出最小的再充电能力。目前的结果表明，GI作为一个F水库，并可以作为一个长期的缓释系统至少32天。
It is well established that glass ionomers (GI) release fluoride (F). The degree of F released depends on the physical and chemical properties of the product. In the present study the fluoride release and the capacity of the GI to be recharged with fluoride was tested for five different brands: XR Ionomer (Kerr), Vitrebond (3M), GC Fuji Lining (G.C. Dental Industries Corp.), Baseline VLC (Dentsply) and Zinomer (Dent. Mat.). Fifteen test specimens were prepared for each brand. The specimens were immersed in deionized water. The F released was measured once a day for 11 days. Refluoridation of the test specimens was done with solutions of 0.02%, 0.04% and 0.2% NaF for 5 minutes on days 11, 16, 21 and 26. The F released from recharged specimens was measured daily until day 32. There was a positive correlation between the amount of F in the GI and the ability to release F. The five materials became 'recharged' with F following repeated F exposure in solution, the 0.2% solution being the most effective. XR ionomer released significantly more fluoride than any other material and showed the greatest ability to be recharged. Zinomer released significantly less fluoride than any other material and showed the least ability to be recharged. The present results indicate that GI serves as a F reservoir and can act as a prolonged slow-release system for at least 32 days.
