In this study, we examined the light transmittance characteristics, include wavelength distribution and diffusion characteristics, for human enamel, dentin and restorative materials such as composite resins, crown and bridge resins, and paint-on resins for shade modification, and evaluated the effect of light transmittance characteristic on color appearance of the materials.The values of overall transmission coefficient of enamel ranged from 0.37 to 0.43 in overall wavelength (400-700 nm). The values were higher than those of composite restorative resins, and almost equal to those of crown and bridge resins, and paint-on resins for shade modification. The crown and bridge resins, and paint-on resins also showed similar light transmittance distribution spectra and diffusion characteristics to enamel. It is desirable for the materials to match color appearance between natural tooth and materials. The results indicate that the light transmittance characteristics play an important role for the color of restorative resins. The significant difference in light transmittance characteristic among materials and shades will affect their clinical appearance.

在这项研究中，我们研究了人类牙釉质、牙本质和修复材料（如复合树脂、冠桥树脂和用于色调修改的涂料树脂）的透光特性，包括波长分布和漫射特性，结果表明，搪瓷的总透光系数为0.37 ~ 0.39，总波长（400-700 nm）为0.43。其值高于复合修复树脂，与冠桥树脂和着色修饰树脂相当。冠桥树脂和涂敷树脂也显示出与牙釉质相似的透光率分布光谱和漫射特性。希望材料与天然牙齿和材料之间的颜色外观相匹配。结果表明，透光特性对修复树脂的颜色起着重要作用。不同材料、不同色调之间的透光特性存在显著差异，这将影响其临床外观。
