The color stability of seven visible light-cured and three chemically-cured composite resins was investigated while being subjected to UV light irradiation and storage in an aqueous environment at elevated temperatures. Color shift was evaluated visually and by colorimetric measurements. Significant correlation was found between visual scoring and colorimetric readings. When subjected to UV light, a wide deviation in color change existed from brand to brand in photocured composite resins. The color shift of chemically-cured composite resins was less than but fell within the range of photocured composite resins. When stored in water at elevated temperatures, photocured resins exhibited better color stability than the chemically-cured composite resins.
研究了七种可见光固化复合树脂和三种化学固化复合树脂在紫外线照射及高温水环境储存条件下的颜色稳定性。通过目视和比色测量对颜色变化进行评估。发现目视评分与比色读数之间存在显著相关性。在紫外线照射下，光固化复合树脂的颜色变化因品牌而异，差异很大。化学固化复合树脂的颜色变化小于光固化复合树脂，但仍在其范围内。在高温水中储存时，光固化树脂比化学固化复合树脂表现出更好的颜色稳定性。
