| ABSTRACT Background: The shade duplication procedure is essential in fabricating ceramic dental restorations, yet there is limited information on color duplication for high translucent zirconia. Aim: To evaluate the color differences between intended and fabricated shades of high translucent zirconia. Materials and Methods: Sixteen square high translucent zirconia specimens were cut in the pre-sintered state and immersed in coloring agents representing the 16 shades of the Vita Classical Shade Guide. After sintering and glazing per the manufacturer's guidelines, visual and instrumental assessments were conducted to determine the corresponding shade of each specimen. These specimens served as master references for the fabrication of experimental specimens based on their respective master shades. Color differences (∆E00) between the master and experimental specimens were analyzed. Results: there was no statistically significant difference in delta E00 between visual and instrumental methods of shade selection. The color difference between intended and fabricated specimens was found to surpass the acceptability threshold. Conclusions: zirconia material colored using dipping technique showed un-acceptable color duplication regardless of the shade selection method used. | ||
