Schematic illustration of standard three-point bending flexure test a). Obtained flexural strain as function of stress for non-irradiated b), 25 kGy c) and 50 kGy d) irradiated PMMA and their corresponding flexural moduli e) and flexural strengths f). There was no significant difference in flexural modulus between non-irradiated and 25 and 50 kGy PMMA. ns, and * represent p > 0.05, p ≤ 0.05, respectively. Values are presented as mean ± SD; n = 8.
