摘要/Abstract

摘要： 目的: 研究填料大小和含量对复合树脂透明度的影响。方法: 每种颗粒大小的填料均以60%、70%、75%和80%的质量分数与基质混合,固化后制备成直径10 mm、厚度1 mm的试件,测定各组试件在标准白板(W)和金属色底板(B)上的色度值。测色系统使用CIELab系统,透明度（TP）根据公式TP=[(L*B-L*W)2+(a*B-a*W)2+(b*B-b*W)2]1/2计算。方差分析颗粒大小和含量对试件透明度的影响,采用SPSS 20.0软件包对均数进行单因素方差分析和HSD检验。结果: 不同直径填料间透明度无显著差异;当填料含量增加时,树脂试件透明度下降。结论: 当填料直径在0.7~1.5 μm范围内变化时,填料含量越高,复合树脂透明度越低。

Abstract: PURPOSE: The objective of this study was to investigate the influences of filler content and size on the translucency parameter of non-layered resin composites. METHODS: Three types of fillers (0.7 μm, 1.0 μm and 1.5 μm) were mixed at weight contents of 60wt%, 70wt%, 75wt%, and 80wt%. The L*, a* and b* value was analyzed based on CIELab color space of the specimen respectively on black and white background. The results of each test were analyzed with one-way ANOVA followed by Tukey's HSD test using SPSS 20.0 software package. RESULTS: For each filler size, there was a trend of decreasing translucency parameter as the filler content increased (P<0.05). The filler size did not affect the translucency parameter of the composites in this study. CONCLUSIONS: When the fillers content changed from 60wt% to 80wt%, there is a trend of decreasing translucency parameter as the filler content increased, and the filler size may not influence the translucency parameter of the composites when the size changed from 0.7 μm to 1.5 μm.
