| Abstract | ||||
| Objective: This study aimed to evaluate the effect of immersion solutions on color stability of two thicknesses of bulk-fill composite and two CAD/CAM ceramics. Materials and methods: One Bulk-fill (X-tra fil) composite (2 and 4mm increment) and two types of CAD/CAM ceramics (ViteEnamic and VitablocsMark II) were used. Forty two composite specimens were prepared with two different thicknesses, also twenty-one specimens of each ceramic material (2 mm in thickness) were prepared for color change evaluation after immersion in distilled water, cola and coffee. Kruskal-Wallis test was used to compare between materials as well as to compare between immersion solutions. Dunn’s test was used for pair-wise comparisons when Kruskal-Wallis test is significant. The significance level was set at P ≤ 0.05. Results: In distilled water there was no statistically significant difference between values of composite and vitaenamic, both were statistically higher than vitamark II, with cola X-trafil 2 mm showed the statistically significantly highest median ΔE, 4 mm showed statistically significantly lower median value, there was no statistically significant difference between ceramics; both showed the statistically significantly lowest median ΔE values. With coffee there was no statistically significant difference between X-trafils; both showed the statistically significantly highest median ΔE values, and no statistically significant difference occurred between ceramics; both showed the statistically significantly lowest median ΔE values. Conclusion: Composites are unable to retain the color they possessed after storage, but the color of both types of ceramic is stable even after immersion and storage in distilled water, cola and coffee. | ||||
