Objectives: The aim of this study was to evaluate the effect of hydrothermal aging on the mechanical properties and translucency of dental zirconia with different levels of translucency.
Methods: Three different types of dental yttria-stabilized zirconia were used: 3Y-TZP (ZrO - 3 mol.% YO) of medium opacity (designated Z3OP), 3Y-TZP of medium translucency (Z3MT), and 5Y-PSZ (ZrO - 5 mol.
