Table 3: Relative quantities of the elements (provided
in wt.%) detected by energy dispersive
X-ray spectroscopy (EDX) on the as-is archwire, and new structures present on
the archwires UA and BA which were immersed in AS for 31 days (Figure 3 and
Figure 4). All the detected Ni and Ti quantities were found
statistically significant with P < 0.01 for UA and P < 0.001 for BA. (Elements with signals lower than
0.1 wt. % were not included in the table.)
