Summary

There is a controversy in the dentistry literature about how the use of associated light to activate 35% hydrogen peroxide gel during in-office tooth bleaching may increase the bleaching effectiveness. The studies that demonstrated an increased level of bleaching using light activation employed lower hydrogen peroxide gels while the ones reporting no statistical difference employed higher hydrogen peroxide gels.

The hypothesis of this study is that the effectiveness of light activation tooth bleaching in dependent on the hydrogen peroxide concentration employed.

Conditions

  • Tooth Discoloration

Interventions

PROCEDURE

in-office bleaching with/without light

Two clinical sessions of tooth bleaching will be performed in each patient with a 1-week interval between them. In each session, three 15-min applications of the gel will be done using one of the two concentrations under investigation. In half of the sample of each concentration, the gel will be activated with a LED/laser device for a total of 3 min, as specified by the DMC manufacturer.
