Figure 2. Bar graph illustrating Vickers hardness (N/mm2) at different curing depths of 4 mm, 2 mm and at the surface. Dotted line (-----) indicates that there was no statistically significant difference between the materials. Straight line (——) indicates that there was no statistically significant difference within the same material at different curing depths.
