Diode Low-power Laser Before In-office Bleaching

a single preliminary treatment for a few seconds for each tooth using low level diode laser before of tooth bleaching could reduce risk to arise of tooth sensitivity

The gingival tissues of the teeth to be bleached were isolated from the bleaching gel using a light-cured resin dam (OpalDam Kit, Ultradent; Milan, Italy). A 38 % ready-to-use Hydrogen peroxide-containing gel (The Smile® Strong, Italy) was applied from the first premolar right to the first premolar left of both jaws for a total period of 20 minutes for a 1 single whitening session.
