目的：体外比较2种含氟流动树脂Beautifil Flow Plus F00和Dyad Flow的短期释氟量,以探讨2种材料释氟能力的差异。方法选取含氟流动树脂F00、DF和不含氟树脂Valux,制备直径10mm,厚1mm的样本,每组10个。将样本分别浸泡于5ml去离子水,第1、2、3、7、14、21、28d使用氟离子选择电极测量去离子水中的氟离子浓度,Va组为对照,比较F00和DF组前3d的单日氟释放及28d内各时间点的累积氟释放情况。结果 F00和Dyad Flow的释氟浓度均第1d最高；前3d单日释氟浓度呈下降趋势,差异有统计学意义(P<0．01)；28d内2实验组均有缓慢持续的氟释放,随着时间延长累积释氟量增加；各个时间点,Dyad Flow组累积释氟量高于F00组,差异有统计学意义(P<0．01)。结论2种含氟流动树脂F00和Dyad Flow第1d氟释放最多,在测试时间内均有低量但持续的释氟能力,Dyad Flow释氟量略高于F00。

Objective To compare the amount of fluoride release of two fluoride-containing flowable resins Beautifil Flow Plus F00 (F00) and Dyad Flow (DF). Methods Two fluoride-containing flowable resins F00 and DF and one fluoride-free resin Valux ( Va ) were selected. Ten samples ( 10mm × 1mm ) of each material were prepared respectively. Each sample was placed into 5 ml de-ionized water and the amount of fluoride released into the de-ionized water was measured by fluoride ion selective electrode at 1, 2, 3, 7, 14, 21 and 28d, respectively. The amount of fluoride release in the first three days and cumulative amount of fluoride release at each time point were calculated for the three materials, with F00 and DF being the test groups and Va being the control group. Results The concentration of fluoride release was the highest in F00 and DF in the first day(0. 0952 ± 0. 0200ug/ml and 0. 1362 ± 0. 0179ug/ml)and decreased significantly during the first three days ( P <0. 01 ) . Both of the fluoride-containing resins exhibited sustained fluoride release in the 28d period. The cumulative amount of fluoride release increased with time and the cumulative amount of fluoride release of DF was higher than F00 at every time point ( P <0. 01 ) . Conclusion The two fluoride-containing flowable resins of F00 and DF presented maximum fluoride release at the first day and exhibited the ability of low and sustained fluoride release during the test period. The amount of fluoride release in DF was higher than that in F00.
