Biaxial flexure strength (BFS; mean value + SD (indicated by bar)) of dry and wet (after 2 weeks immersion in saline solutions) UDMA, PEG-U and UDMA/PEG-U copolymers and their composites. The number of runs in each experimental group n ≥ 3. Standard deviation (SD) is taken as a measure of the standard uncertainty.
