This study aimed to determine the influence of surface roughness of the color adjustment potential restoration of universal resin composites. A structural colored resin composite (Omnichroma, OC) and a pigment-employed universal shade resin composite (Beautifil Unishade, BU) were used. Each resin composite was placed in a cavity to determine its ability to match the color of artificial teeth. The surface of the resin composites was polished with #800- or #2000-grit SiC paper before performing color measurements. One-way analysis of variance and Tukey post hoc tests were performed (α=0.05). The color difference (ΔE*ab) ranged from 2.5-3.9 for OC and 1.8-8.7 for BU. OC has a more stable color adjustment than BU. The color adjustment potential of universal resin composites was affected by the surface roughness of the restorations.
本研究旨在确定通用树脂复合材料颜色调整潜力修复体表面粗糙度的影响。使用了一种结构性彩色树脂复合材料（Omnichroma，OC）和一种使用颜料的通用色度树脂复合材料（Beautifil Unishade，BU）。将每种树脂复合材料置于窝洞中以确定其匹配人造牙颜色的能力。在进行颜色测量之前，用#800或#2000粒度的碳化硅砂纸对树脂复合材料的表面进行抛光。进行了单因素方差分析和Tukey事后检验（α=0.05）。OC的颜色差异（ΔE*ab）范围为2.5 - 3.9，BU为1.8 - 8.7。OC的颜色调整比BU更稳定。通用树脂复合材料的颜色调整潜力受修复体表面粗糙度的影响。
