Background and Aim: There is a growing demand for esthetic dental treatments with composite resins like Ceram.x SpectraTM ST® (CS) due to the importance of a beautiful smile; but color change may occur affecting the longevity and quality of composite restorations. The purpose of this study was to evaluate the color stability of a composite resin, subjected to two different polishing systems, after immersion in different coloring solutions (common beverages).
Materials and Methods: Forty specimens were fabricated from CS nanoceramic composite resin and polished with Enhance® and Astropol® finishing and polishing systems. The CIE L*a*b* color parameters were measured before and after immersing the specimens in coffee, red wine, and Coca-Cola. The chromatic difference was assessed by calculating the ∆E. Two-way ANOVA was applied to compare the ∆E values based on the type of polishing system, coloring solution, and their interaction.
Results: Astropol® resulted in better color stability and smoother surfaces than Enhance®. Wine and coffee significantly changed the color stability of tested composite resin (P<0.05), while Coca-Cola did not affect the color stability (P>0.05).
Conclusion: The choice of dental finishing and polishing system affects the color stability of CS composite resin following exposure to commonly consumed drinks.
