Abstract

Abstract The aim of this study is to evaluate the effect of an office bleaching agent on the color of various single-shade resin composites. Three single-shade resin composites were tested in this study. Thirty disk-shaped specimens were prepared with a diameter of 10 mm and a height of 1 mm, and they were divided into three groups (n = 10). After color measurements, 40% hydrogen peroxide containing bleaching agent gel was applied to all the specimens. Baseline and final color measurements were performed using a clinical spectrophotometer. Statistical analyses were performed. All bleached specimens had clinically incomprehensible color changes (ΔE < 3.3). Comparisons for single-shade composites revealed no statistically significant color difference between groups. With the limitation of this study in mind, color changes in single-shade resin-composites after office bleaching were found to be clinically acceptable. It may be appropriate to use single-shade composites that shorten the in-chair clinical time by facilitating shade selection.

用仪器法评价三种单色树脂复合材料在办公室漂白前后的颜色匹配度

摘要本研究的目的是评价一种办公室漂白剂对各种单色树脂复合材料颜色的影响。本研究对三种单色树脂复合材料进行了测试。制备直径为10 mm，高度为1 mm的盘状标本30个，分为3组(n = 10)。颜色测量后，将含40%过氧化氢漂白剂凝胶涂于所有标本上。使用临床分光光度计进行基线和最终颜色测量。进行统计学分析。所有漂白标本均有临床上难以理解的颜色变化(ΔE < 3.3)。单色复合材料的比较显示各组之间没有统计学上显著的颜色差异。考虑到本研究的局限性，单色树脂复合材料在办公室漂白后的颜色变化在临床上是可以接受的。使用单色复合材料可能是合适的，通过促进遮光材料的选择，缩短了在椅子上的临床时间。
