To determine color stability of two different composites resins with same shade using LED and halogen light cure upon exposure to different types of staining media.
Methods: The colors of all specimens before and after storage in the solutions were measured by a spectrophotometer based on CIE Lab system, and the color differences thereby calculated. Data were analyzed by two-way analysis of variance (ANOVA) and Scheffe’s post hoc test.
Results: Overall, the highest ΔE was observed with Z350 material, halogen light cure, mustard staining media, and at 30 days time. There was statistically significant mean difference (ΔE) between all the staining media except between ketchup and distilled water. Similarly, a statistically significant mean difference (ΔE) was found between all time periods except between one day and baseline.
Conclusion: It can be concluded that all staining media used in this study affected the color stability of the tested materials with time. Further studies with longer period of aging are warranted by the findings of this study.
