The objective of the study was to evaluate the physical properties of four resin-modified glass-ionomer cements (Fuji II LC, Ionosit Fil, Vitremer, Photac-Fil) and two polyacid-modified resin composite materials (Dyract and Variglass VLC)). They were compared with a hybrid resin composite (blend-a-lux) and a chemically cured glass-ionomer cement (ChemFil Superior). The compressive strength, flexural strength, modulus of elasticity, and surface microhardness of the resin-modified glass-ionomer materials and the polyacid-modified resin-composite materials were inferior to those of the hybrid resin composite and similar to those of the conventional glass-ionomer cement. The hybrid resin composite exhibited the lowest resistance to wear caused by brushing. Some of the materials showed a marked decrease in hardness at depths exceeding 2.0 mm. Generally, the strength properties of the tested resin-modified glass-ionomer materials and the polyacid-modified resin composite materials were inferior to those of the hybrid resin composite.
本研究的目的是评估四种树脂改性玻璃离子水门汀（富士II LC、Ionosit Fil、Vitremer、Photac-Fil）和两种聚酸改性树脂复合材料（Dyract和Variglass VLC）的物理性能。将它们与一种混合树脂复合材料（blend-a-lux）和一种化学固化玻璃离子水门汀（ChemFil Superior）进行比较。树脂改性玻璃离子材料和聚酸改性树脂复合材料的抗压强度、抗折强度、弹性模量和表面显微硬度均低于混合树脂复合材料，与传统玻璃离子水门汀相似。混合树脂复合材料表现出最低的刷牙磨损抗性。一些材料在超过2.0毫米的深度处硬度显著降低。总体而言，所测试的树脂改性玻璃离子材料和聚酸改性树脂复合材料的强度性能低于混合树脂复合材料。
