Effect of Recasted Material Addition on the Quality of Metal-Ceramic Bond: A Macro-, Micro-, and Nanostudy

Table 5

The mean values of hardness (±SD) for each group of specimens.

Specimen	HV 0.5 ± SD
100	253 ± 9.4^a
50	271 ± 4.7^b
0	262 ± 6.5^a

The mean values with dissimilar indices are significantly different at . The letters a and b indicate the existence of significant differences between the mean values of hardness.
