Table 2.
Shear bond strength (MPa) of different materials under different aging and bonding conditions. The results are presented as the mean value (standard deviation). The values with the same lower case superscript letter per row indicate statistically homogenous groups. The values with the same upper case superscript letter per column for each test group indicate statistically homogenous groups (Tukey test, α = 0.05).
