Purpose: This study was conducted to investigate the colors of zirconia and veneered ceramics according to the build-up method of veneer porcelain. Methods: The samples were divided into three groups: a group for which a liner was applied to the zirconia surface and dentine coating was built up and burned (Cz1), a group for which the dentine coating was directly built up and burned (Cz2), and a group for which the samples were wash-burned with dentine coating and a dentine coating was built up and burned again (Cz3). The the colors were measured with a Spectrophoto-meter. Results: The average L* value of the Cz3 group was the highest among the groups at 59.1 0.5 (P<0.05), followed by Cz2 at 57.5 0.8 and Cz1 at 56.6 1.3. The a* value of Cz3 was negative at -0.0 0.0 and the a* values of Cz2 and Cz1 were positive at 0.2 0.1 and 0.4 0.0, respectively (P<0.05). The b* of Cz1 was the highest at 11.2 0.6, followed by Cz3 at 10.8 0.5 and Cz2 at 10.5 0.8 (P<0.05). Conclusion: Compared to other experimental groups, the Cz3 groups showed the brightest colors with high brightness and relatively low green and yellow levels.
