Effects of abrasive and fiber components in a medium on the wear behavior of composite resins were evaluated. Calcium diphosphate and methyl cellulose were included in the medium as abrasive and fiber components respectively. A range of 0, 4, or 8% abrasive- or fiber-containing media were applied on a composite resin specimen during a simulated occlusal wear test. Four composite resins, Clearfil AP-X, Z100 Restorative, SOLARE P, and SOLIDEX F, were tested to evaluate the effects of these components in the medium. Presence of abrasive material in the medium increased the wear of composite resins significantly, but its effect differed among the composite resins. Presence of fiber material in the medium significantly decreased the wear of two composite resins, whereas the other two composites showed no significant differences. Nonetheless, presence of fiber in the medium generally tended to prevent the wear of composite resins.
评估了介质中的磨料和纤维成分对复合树脂磨损行为的影响。分别将磷酸二钙和甲基纤维素作为磨料和纤维成分添加到介质中。在模拟咬合磨损试验期间，将一系列含0%、4%或8%磨料或纤维的介质施加于复合树脂试样上。测试了四种复合树脂Clearfil AP-X、Z100 Restorative、SOLARE P和SOLIDEX F，以评估介质中这些成分的影响。介质中磨料的存在显著增加了复合树脂的磨损，但其影响在复合树脂之间有所不同。介质中纤维材料的存在显著降低了两种复合树脂的磨损，而另外两种复合树脂则没有显著差异。尽管如此，介质中纤维的存在总体上倾向于防止复合树脂的磨损。
