Polymerization plays an important role in the color and translucency of resin composite materials. The aim of this study was to evaluate the effect of light-curing distances of resin composites on color change (ΔE00) and translucency change (ΔTP) after accelerated aging (AA). Four resin composites (G-Aenial Anterior, Charisma Smart, GrandioSO, and Admira Fusion) were used. The resin composites were cured from 0 mm, 2 mm, and 4 mm distances. A spectrophotometer was used to determine the color measurements and calculate the color change and translucency using the CIEDE2000 formula. The resin composites were submitted to AA for 300 h. Two-way analysis of variance and multiple comparisons Tukey’s test were used (p < 0.05). ΔE00 at 0 mm and 2 mm distance was similar, but higher was found at 4 mm distance. The highest and lowest ΔE00 were observed in the G-Aenial Anterior and Charisma Smart respectively. But no differences were observed between Charisma Smart and Admira Fusion. Translucency changes at 2 mm and 4 mm distances were similar, but lower translucency changes were observed at a distance of 0 mm. The translucency change values of the materials were found to be similar after accelerated aging. Increasing the light-curing distance can lead to deterioration of color stability and a tendency to decrease translucency. Clinicians should position the light-curing device as close to the material as possible.
