Summary

Background: The aim of study was to investigate the effectiveness of low-level laser therapy (LLLT) use before in-office bleaching to prevent risk and intensity of tooth sensitivity.

Methods: thirty patients were selected for this clinical trial. Before bleaching procedures with 38 % hydrogen peroxide, the participants were randomly divided into two groups of 15 subjects. Test group: the patients teeth received a preliminary LLLT procedure by an 810 nm diode laser with 0.5 Watt for 30 s for an energy density of 15 J/cm2 and a group placebo: the patients received the same preliminary LLLT but with the device switch off. All patients were instructed to report their cold sensitivity experiences immediately, 1 h, 24 h, and 48 h after the end of bleaching by a visual analog scale score between 0-10.

Conditions

  • Tooth Sensitivity

Interventions

DEVICE

Low-level laser treatment

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

OTHER

tooth bleaching procedure

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.
