Figure 6. Effects of QAMS concentration on the flexural properties of the orthodontic acrylic resins (N = 10).

Figure 6

A. Ultimate flexural strength. B. Flexural modulus. For each parameter, the ISO requirement is included for comparison (dotted line). For the ultimate flexural strength, groups with the same upper case letter designators are not statistically significant (P>0.05). For flexural modulus, groups with the same lower case letter designators are not statistically significant (P>0.05). Values represent means and standard deviations.
