Mechanical properties, diametral tensile strength (DTS) and flexural strength (FS) of six fluoride releasing materials were measured and compared. The samples were prepared and tested according to ISO specifications. The materials included a glass ionomer (Fuji IX), a resin-modified glass ionomer (Photac-Fil), two compomers (F 2000; Dyract AP) and two composites (Solitaire; Tetric Ceram). The tests were performed after the materials were stored in distilled water (DTS) and phosphate buffered saline solution (FS) at 37 degrees C for 24 hours and one week. Fluoride-releasing composite resin had the highest flexural and diametral tensile strengths and were statistically stronger than compomers, followed by resin-modified glass ionomer and conventional glass ionomer. However, a notable exception to this general trend was Solitaire, a fluoride-releasing composite resin.
测量并比较了六种含氟材料的机械性能、径向拉伸强度(DTS)和弯曲强度(FS)。根据ISO规范制备并测试样品。材料包括一种玻璃离子水门汀(Fuji IX)、一种树脂改性玻璃离子水门汀(Photac-Fil)、两种复合体(F 2000;Dyract AP)和两种复合材料(Solitaire;Tetric Ceram)。在材料于37摄氏度的蒸馏水(DTS)和磷酸盐缓冲盐溶液(FS)中储存24小时和一周后进行测试。含氟复合树脂具有最高的弯曲强度和径向拉伸强度,且在统计学上比复合体更强,其次是树脂改性玻璃离子水门汀和传统玻璃离子水门汀。然而,这一总体趋势的一个显著例外是含氟复合树脂Solitaire。
