Effect of Light-Curing Distances on the Color and Translucency of Resin Composites After Accelerated Aging

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
