Concerning the color differences (¥ÄE*) caused by the difference in the light source (C and D65, C and A, A and D65), white shade resin composites showed higher color differences in all three conditions of uncured, cured and
thermocycled.
Standard light source A was prominently different from C or D65. ¥ÄE* with SCI mode was similar to those of SCE mode.

The color changes after curing of white shade resin composites were significantly higher than those of conventional shades of resin composite regardless of the light source and measuring mode in both materials. The color change(¥ÄE*)
after
curing was 6.3¡­12.8 with SCE mode and 4.5¡­12.3 with SCI mode, and color changes measured with SCE mode was higher than those measured with SCI. The color changes of translucent shades were generally higher than those of conventional shades
after
curing regardless of measuring mode. The color change after curing and thermocycling was influenced by the shade and translucency of resin composites.

The color distributions of two shade guides were illogical, and the color of the new shade resin composite were different depending on the manufacturer. The color of shade guide and resin composite were perceivably different depending on the
measuring
mode. So, new systematic shade guide, in which shades are logically rearranged and new shades of resin composite are included should be developed.
