Baseline and 30-day modulus of elasticity of completely demineralized dentin beams cross-linked with different PVPA concentrations (100 - 3,000 μg/mL) and incubated in a calcium- and zinc-containing aging medium for 30 days. Specimens without PVPA cross-linking immersed in same aging medium were used as the control. Data are presented as least square mean with a common standard error of the least square mean (0.109 MPa). For the baseline period, groups with the same lower case letter are not statistically significant (p > 0.05). For the 30-day period, groups with the same upper case letter are not statistically significant (p > 0.05). For each PVPA concentration as well as the control, time-period columns connected by a solid black bar are not statistically significant from one another (p > 0.05).
