Comparison of Masking Ability of Milled and <scp>3D</scp> ‐Printed Monolithic Zirconia on Discolored Substrates
All zirconia specimens showed clinically acceptable masking ability against a normal dentin shade (ND<sub>3</sub>) (< 1.8). Also, printed zirconia (1 mm) against ND<sub>3</sub> substrate showed the highest masking ability. Moreover, only 1 mm printed zirconia over a darker shade of dentin (ND<sub>5</sub>) showed a clinically acceptable color difference. However, no zirconia specimen could mask severely discolored dentin (ND<sub>9</sub>).
