Table 1.
Results of atomic percent [At%] and Ca/P ratio at the enamel surface following treatment according to group (n = 12). Since data are not symmetrically distributed, and some of the sums of the medians may differ from 100%. Asterisks indicate significant difference between the respective group and the control (Aqua demin). Data are also depicted in Figure 2 and Figure 3.
