Objective: The aim of this study was to evaluate the time-dependent changes in optical properties of recent tooth-colored restorative materials in commonly used coloring beverages.
Method: A total of 200 specimens of four different materials (Alkasite, ACTIVA, Equia Forte, Zirconomer) and a composive material as the control group were prepared in Teflon molds and the materials were immersed in four different solutions (coffee, cola, ice tea and saliva) (n=10). Color measurements were performed with a spectrophotometer at baseline, 7, 14 and 28 days. Color changes, translucency parameters (TP) and contrast ratios of the materials were calculated. The data were analyzed by repeated measurements and three-way ANOVA and post hoc Tukey tests.
Results: Alkasite showed the greatest color change for all solutions in all immersion periods compared to other materials (p<0.001). The experimented solutions caused a perceptible color change in all materials after 28 days (p<0.05). Coffee and ice tea caused more staining of resin-based materials for all immersion periods (p<0.05). Initial TP and ∆TP of glass ionomer-based materials were found to be lower than the resin-based materials.
Conclusion: Exposure of the recent materials to different solutions for a certain period of time caused significant changes in optical properties. Resin-based alkasite, ACTIVA and composite showed the highest change the optical properties in coffee and ice tea.
