Abstract
Purpose: In this study, in order to provide objective standard of the mixed concentration of the zirconia coloringliquids, compare the shade differences after colored zirconia blocks from different concentrations.
Methods: After immersion for 2 minutes zirconia specimen (1.5 1.5 0.6 0.01 ) in coloring-liquids that produced different concentrations, were sintered in furnace dedicated. Then, it was measured in spectrophotometer and Shadepilot. It has been determined mean and standard deviation of the color difference for each group, and verified by one-way ANOVA using the (version12.0) SPSS WIN Program the difference in shade according to the concentration at the significance level of 95% confidence, it conducted a Tukey’s multiple range test to post-test.
Results: The mean of L* was decreased toward LN35 group, however the mean of a and b was increased p<.05). There is a statistically significant difference in the results of L post hoc test of each group was LN15-LN30/LN35,
LN20-LN30/LN35, LN25-LN30/LN35, and LN30-LN35 group. The a* group, it was found that there is a statistically significant difference in all groups for each(p<.05). The b* group, it was found that there is a statistically significant difference in all groups except the LN25-LN30(p<.05).
Conclusion: In order to make effective use of the coloring-liquids of zirconia, the device objective, accurate concentration measurement is required, from the present study, we presented evidence basic to this.
