The purpose of this article was to review the changes in translucency of direct esthetic restorative materials after curing, aging and treatment. As a criterion for the evaluation of clinical translucency changes, visual perceptibility threshold in translucency parameter difference (ΔTP) of 2 was used. Translucency changes after curing were perceivable depending on experimental methods and products (largest ΔTP in resin composites = 15.9). Translucency changes after aging were reported as either relatively stable or showed perceivable changes by aging protocols (largest ΔTP in resin composites = -3.8). Translucency changes after curing, aging and treatment were perceivable in several products and experimental methods. Therefore, shade matching of direct esthetic materials should be performed considering these instabilities of translucency in direct esthetic materials.
本文旨在综述直接美学修复材料在固化、老化和处理后的透明度变化。作为评估临床透明度变化的标准，使用了透明度参数差异（ΔTP）为2时的视觉感知阈值。固化后的透明度变化因实验方法和产品而异（树脂复合材料中最大ΔTP = 15.9）。老化后的透明度变化据报道要么相对稳定，要么根据老化方案显示出可感知的变化（树脂复合材料中最大ΔTP = -3.8）。在几种产品和实验方法中，固化、老化和处理后的透明度变化是可感知的。因此，在进行直接美学材料的比色时，应考虑这些直接美学材料透明度的不稳定性。
