本研究比较了传统玻璃离子Ketac-Molar（ESPE）、树脂改性玻璃离子Vitremer（3 M）以及两种复合体F-2000（3 M）和Hytac（ESPE）的初始氟化物释放和再氟化后的释放。为每个品牌制备15个试样，并浸入去离子水中。每2天测量一次释放的氟化物，持续22天。在第22、30、38和46天，用0.02、0.04和0.2% NaF溶液对供试品进行再氟化5 min。每2天测量一次从再充电样本中释放的氟化物，直到第54天。氟的释放量在制备后的第一天最高，之后急剧下降，然后缓慢下降。在溶液中反复暴露氟化物后，这四种材料变得“重新充电”，0.2%的溶液是最有效的。从临床的角度来看，从这项研究的结果意味着，所有的修复材料测试可以作为口腔内装置的控制缓慢释放的氟化物在复发性龋齿的风险的网站。四种新型释氟修复材料对氟的释放和吸收。
The present study compared the initial fluoride release and release following refluoridation of a conventional glass-ionomer Ketac-Molar (ESPE), a resin-modified glass-ionomer, Vitremer (3M), and two compomers F-2000 (3M) and Hytac (ESPE). Fifteen test specimens were prepared for each brand and immersed in deionized water. The fluoride released was measured every 2 days for 22 days. Refluoridation of the test specimens was done with solutions of 0.02, 0.04 and 0.2% NaF for 5 min on days 22, 30, 38 and 46. The fluoride released from recharged specimens was measured every 2 days until day 54. The fluoride release was highest during the first days after preparation, after which it decreased sharply and then more slowly. The four materials became 'recharged' with fluoride following repeated fluoride exposure in solution, the 0.2% solution being the most effective. From a clinical point of view, the results from this study imply that all the restorative materials tested may act as intra-oral devices for the controlled slow release of fluoride at sites at risk of recurrent caries.
