Fig.6.

A measure of the lost mechanical properties from the reduced elastic modulus (E_r) vs. distance curves after demineralization with an upper boundary provided by the value of sound dentin (light blue region; A). This represented the Recovery Goal that was sought for remineralization. The Recovery Gained was defined as the area between the demineralization curve (blue line) and the E_r curve (black dotted line) after remineralization (gray region; B). Recovery (%) was ratio of the Gain/Goal × 100.
