Aim: The purpose of this study was to investigate the color stability of nano-hybrid, micro-hybrid, and silorane-based composite resin restorative materials upon exposure to staining agents.
Materials and Methods: One hundred twenty composites samples were prepared, 40 from each composite material (Filtek ® Z350, Filtek ® P90, and Filtek ® Z250). The specimens were randomly divided into four groups (10 of each sample). The specimens were incubated for 24 h in distilled water and then for 72 h in corresponding mediums (distilled water, red grape juice, green tea, coffee). The color of all the specimens was assessed before and after exposure with a spectrophotometer and total color change (ΔE) was calculated using ΔE* = [(ΔL*)2 + (Δa*)2 + (Δb*)2]1/2. The data were analyzed with one-way analysis of variance (ANOVA) and Kolmogorov-Smirnov and the means of the solutions were compared by Tukey«SQ»s honestly significant difference (HSD) (P < 0.05).
Result: The lowest dicoloration was observed in Filtek ® LS P90 but it was not significant while the most discoloration was observed in Filtek ® Z350 and Filtek ® Z250. Also, coffee showed a highly significant (P > 0.05) discoloration compared with other media.
Conclusions: Within the limitations of this study, it may be concluded that silorane-based composites are more resistant to discoloration than bis-GMA-based composites and coffee had the highest effect on composite discoloration compared to other media.
