Figure 3. Dry (solid circles) and wet (solid squares) magnitudes of the indentation Young’s modulus (E) of normal (N), pulpal region of the altered dentin (DI+), and mid-coronal region of the altered (DI) dentin. The error bars represent the standard deviations in the measured magnitudes (N = 3). There was a linear relationship (R2 = 0.99) between the mineral concentration and the Young’s modulus in the dry dentins, in agreement with Eq. 1.2. The correlation with mineral concentration vanished when the dentin was hydrated. Similar behavior was observed for hardness.
