Table 4:

Comparison of resin and composite flexural elasticity, flexural strength, flexural toughness from the three-point bend testing. The letters indicate statistically significant differences (p<0.05) via a one-way ANOVA and a Tukey’s post-hoc test (capital letters for row and lowercase for column).
