Influence of loading rate on the elastic modulus of the demineralized dentin. Indentation tests were performed at loading rates of 1, 10 and 50 µm/sec. a) at 0.25% strain in water; b) at 0.25% strain in ethanol, c) at 1% strain in water, d) at 1% strain in ethanol. Note the difference in scales used for presenting the data in (a) – (d). Boxes with different letters indicate significant differences (p≤0.05).
