Abstract
Purpose: The aim of this study was to evaluate the effect of colored zirconia with different coloring liquids.
Methods: Total 30 specimens were prepared. Specimens were classified into 6 groups: IPS e.max Ceram(P), Uncolored zirconia(C), VITA In-Ceram 2000 YZ LL1(L), Zirkonzahn coloring liquid(Z), Wieland coloring liquid(W), and Kuwotech coloring liquid(K). Four different types of zirconia coloring liquid, VITA In-Ceram 2000 YZ LL1(VITA Zahnfabrik, Germany), Zirkonzahn coloring liquid(Zirkonzahn, Italy), Wieland coloring liquid(Wieland, Germany), Kuwotech coloring liquid(Kuwotech, Korea) were used to fabricate colored zirconia by using infiltrating method and then completely sintered. The color of the all specimens was measured using the spectrophotometer(CM-2600d, Konica Minolta, Japan) and expressed in terms of the 3-coordinated values(CIE L*a*b*). Color differences were calculated using the equation E*= [( L*)2+( a*)2+( b*)2]1/2.
Results: L*a*b* values of the colored zirconia were affected by the coloring liquids. The uncolored zirconia(C) group showed the highest L* value and zirkonzahn coloring liquid(Z) group showed the lowest L* value. Zirkonzahn coloring liquid(Z) showed the highest a* value and VITA In-Ceram 2000 YZ LL1(L) group showed the highest b* value. Generally, the color difference( E*) in all groups showed higher than 3.7 except between IPS e.max Ceram(P) and wieland coloring liquid(W) group.
Conclusion: Within the limitations of this study, various coloring liquids influenced the L*, a*, and b* values of colored zirconia. IPS e.max Ceram(P) and wieland coloring liquid(W) group did not show clinically perceiving color difference.
