Abstract

Aim: The aim of this study is to compare the color stability of different universal composites and to evaluate the effects of keeping them in water for 1 week before coloring.


Methodology: Filtek Ultimate (FU), Estelite Ʃ Quick (EQ), and Ceram X One (CX) composites were used. The specimens were kept in the dark, dry environment for 24 hours, then polished, and each composite group was divided into 3 groups: the control, the group that was kept in water for 1 week before coloring and coloring (n=7). The samples in the control group were kept in distilled water for 3 weeks. Samples in the coloring group were colored with coffee for 2 weeks (C), and the samples in the last group were kept in water for 1 week and then stained with coffee for 2 weeks (W+C) (n=7). Color measurements for all samples were taken twice, once before and once after the coloring period. The color changes of the samples were measured using the ∆E* parameter, which was calculated with before and after measurements. 


Results: For all composite resins, the ΔE values of the samples in the W+C and C groups were significantly higher than those in the control group. When the composites were compared with each other, the differences between the ΔE values of the composites in the control, W+C, and C groups were not statistically significant. For FU and ESQ, at the end of the coloration period, there were no statistically significant differences between the W+C and C groups. However, for CX, the color change of the samples in the W+C group was significantly higher than that in  the C group.


Conclusion: Storage in distilled water for 1 week before staining did not reduce the color change values of the samples. Thus, after composite restorations are performed, there is no need to advise patients to avoid staining foods, especially in the first week after restoration.
