英文摘要Indirect resin composites are generally regarded to have better color stability than direct resin composites since they possess higher conversion degree. Objective: The present study aimed at comparing the changes in color (Delta E) and color coordinates (Delta L, Delta a and Delta b) of one direct (Estelite Sigma: 16 shaddes) and 2 indirect resin composites (BelleGlass NG: 16 shades; Sinfony: 26 shades) after thermocycling. Material and Methods: Resins were packed into a mold and light cured; post-curing was performed on indirect resins. Changes in color and color coordinates of 1-mm-thick specimens were determined after 5,000 cycles of thermo cycling on a spectrophotometer. Results: Delta E values were in the range of 0.3 to 1.2 units for direct resins, and 0.3 to 1.5 units for indirect resins, which were clinically acceptable (Delta E < 3.3). Based on t-test, Delta E values were not significantly different by the type of resins (p > 0.05), while Delta L, Delta a and Delta b values were significantly different by the type of resins (p < 0.05). for indirect resins, Delta E values were influenced by the brand, shade group and shade designation based on three-way ANOVA (p < 0.05). Conclusion: Direct and indirect resin composites showed similar color stability after 5,000 cycles of thermocycling; however, their changes in the color coordinates were different.
