摘要

本研究採討七種可見光聚合樹脂及三種化學性聚合複合樹脂之顏色穩定性。使用測試環境分別為紫外線照射法及儲存37℃與6℃水溫法。顏色變化程度分別用目視法及顏色測度儀來記錄。統計學分析顯示此兩種記錄法具有有意義的相關。在紫外線照射下，不同廠牌的可見光聚合樹脂呈現相當大的變色範圍，而化學性聚合複合樹脂的程度則較小。在儲存於60oC 水溫6週後，除command ultrafine 外，可見光聚合複合樹脂比化學性聚合複合樹脂有較佳的顏色穩定性。

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.
