Flexural Strength of Vitreous Ceramics Based on Lithium Disilicate and Lithium Silicate Reinforced with Zirconia for CAD/CAM

Figure 6

Bar graph of Vickers hardness of ceramics. Analysis of variance with Tukey’s multiple comparison test was used to compare the hardness of ceramics in this study. ^∗ represents the significant difference between the groups and (ns) represents the nonsignificant values.
