Means (SD) of the flexural strength (FS, MPa), flexural modulus (FM, GPa) and toughness (MPa) for all groups tested. Different HDDMA concentrations were added to materials without (0 wt%) or with (10 wt%) thiourethane oligomer. Values followed by the same letters in each column are statistically similar (α=0.05).
