Fig 6a-c: Digital simulation of the shade change expressed in bleached indexes from the initial, clinically measured bleached index 16 right and left
to end values. A change in tooth shade is visible
Fig 7a-c: View of systematically clinically measured bleached indexes in the new module before the whitening procedure (Figure 7a), after
one week of wearing a custom tray and whitening with 16% carbamide peroxide during the night (Figure 7b) and after two weeks. (Figure 7c).
Continuous monitoring shows a decrease in the value of the bleached index, which proves a positive change, i.e., an increase in lightness and a
decrease in shade saturation of treated teeth.
