Abstract
Purpose: The color of dental zirconia is very important in terms of aesthetics. To reproduce the color tone, a colorant is applied to zirconia to express the color tone. I would like to point out that the color, brightness, and saturation of the colorant used to express the color A3 may vary depending on the manufacturer.
Methods: Each zirconia block received a total of 25 circular specimens for the experiment. The zirconia specimen was then deposited by colorant type to reproduce the color tone. Color differences and translucency were measured using a spectrophotometer. To compare and analyze the zirconia color according to the type of colorant, one-way ANOVA was used.
Results: For each type of zirconia colorant, there was no statistically significant difference in translucency or b* (p>0.05). There was a statistical difference in L* and a* (p<0.05).
Conclusion: The ΔE*ab (D65) value is less than 5.5 or less, and the color difference is within an acceptable range.
