Accelerated Aging Effects on Color and Translucency of Flowable Composites

Objectives To evaluate the effect of accelerated aging on color and translucency parameter of composites. Materials and Methods Filtek Supreme Ultra Flowable, shades A1, A3, White, Tetric EvoFlow, shades A1, A3, Bleach, and Filtek Z250 shades A1, A3, B1 were evaluated. Color and translucency were recorded using a spectrophotometer after 24‐hour storage (baseline) and after accelerated aging. The data were analyzed by analysis of variance. Results Fisher's PLSD intervals for comparisons among products and shades were 0.4, 0.1, 0.3, and 0.4 for ΔL*, Δa*, Δb*, and ΔE*, respectively. The data showed significant ΔE* and ΔL* main effects for composite product and shades (p 0.05). Conclusion The effects of aging on color of resin composites were composite and shade dependent. Translucency was not affected by accelerated aging. Clinical Significance The effects of aging on color of resin composites were composite and shade dependent.
