In the article titled “Determination of Hardness and Fracture Toughness of Y-TZP Manufactured by Digital Light Processing through the Indentation Technique” [1], incorrect images were used for Figures 1 and 2 due to an error during the preparation of the manuscript. Figures 1 and 2 should be corrected as follows:

(a)

(b)

Figure 1: SEM images of the zirconia surface of the (a) DLP group and (b) MILL group at magnification ×40k and ×20k.

Figure 2: XRD patterns of zirconia.
