For each horizontal row: values with identical numbers indicate no significant difference using Friedman's and Wilcoxon pair-wise comparisons tests (p>0.05).
For each vertical column: values with identical low case letters indicate no significant difference between solutions within the same dentin treatment and values with identical upper case letters indicate no significant difference between treatments within the same solution, using Student-Newman-Keuls test (p<0.05).
