Abstract

PURPOSE

To compare the fluoride levels released from a polyacid-modified resin composite (Ultra BandLok), a resin-modified glass-ionomer cement (Multicure) and a conventional glass-ionomer cement (Meron).

METHODS

Fluoride concentration in the deionized water was measured at 1, 2, 3, 7, 14 and 28 days. Fluoride measurement was undertaken using a fluoride ion selective electrode connected to an ion-analyzer. Friedman test was used in the repeated measurements of multiple groups. Kruskal-Wallis test was used to compare the groups. Dunn's multiple comparison test was applied for the comparison of subgroups.

RESULTS

The fluoride release pattern of the three materials was similar. The highest level of fluoride was obtained at the 24-hour measurement from all samples. According to comparisons among materials, Ultra BandLok released significantly less fluoride than Multicure and Meron (P < or = 0.01) at all the measurement times. In addition, the differences between the fluoride concentrations released from Multicure and Meron materials at all measurement days were not significant (P> 0.05).

摘要

目的

比较一种聚酸改性树脂复合材料（Ultra BandLok）、一种树脂改性玻璃离子水门汀（Multicure）和一种传统玻璃离子水门汀（Meron）释放的氟化物水平。

方法

在第1、2、3、7、14和28天测量去离子水中的氟化物浓度。使用连接到离子分析仪的氟离子选择性电极进行氟化物测量。Friedman检验用于多组重复测量。Kruskal-Wallis检验用于比较各组。Dunn多重比较检验用于亚组比较。

结果

三种材料的氟化物释放模式相似。所有样品在24小时测量时获得最高氟化物水平。根据材料间比较，在所有测量时间，Ultra BandLok释放的氟化物明显少于Multicure和Meron（P≤0.01）。此外，在所有测量日，Multicure和Meron材料释放的氟化物浓度之间的差异不显著（P>0.05）。
