Dental resin composites have been widely used in clinical, because of its operability and sensuousness. Since the resin composite is subject to cyclic stress in the oral environment, an understanding of the fatigue strength of these materials is needed to use with keeping safety. In this study, three-point bending fatigue tests of resin composites with several filler blend ratios were conducted to investigate the effect of filler size and filler content on fatigue strength. In order to consider an environmental property of the resin composite, the fatigue strength was also investigated in ethanol solution.
