%SMHR test was used to assess mineralization status of enamel specimens using a Wilson 2100 Hardness tester. %SMHR was determined by measuring the length of the indentations of enamel specimens. An increase in the indentation length compared to the baseline indicates softening while decrease in the indentation length represents rehardening of enamel surface. %SMHR was calculated from indentation values of enamel specimens at baseline (B), after intra-oral exposure (R) and after in-vitro demineralization (D) using formula: \[(D-R)/ (D-B)\]\*100.
