Fig. 2

Mechanical properties of flowable composite resins containing strontium-modified phosphate-based glass, with clear differences observed before (A, C, E) and after (B, D, F) thermocycling for testing; (A, B) Flexural strength, (C, D) elastic modulus, and (E, F) Vickers microhardness. Different lowercase letters above the error bars indicate significant differences, as determined by the Tukey’s post-hoc test. Error bars represent the standard deviation of the mean.
