Dental hypersensitivity after office dental bleaching.
Conditions
Interventions
Low-power laser therapy applied after office tooth whitening. 25 participants are part of the intervention and control groups. Photobiomodulation was done in 2 moments, immediately after bleaching and

Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Effectiveness of office tooth whitening at different times of color evaluation maintained in the 2 research groups.;The results showed no statistically significant difference in relation to the color variation between the groups. | — |
Primary
| Measure | Time frame |
|---|---|
| The photobiomodulation protocol with a wavelength of 808 nm and a focal size of 0.028 cm², with a therapeutic dose activated at 0.10W power for 25 seconds at each point (50 seconds per tooth), with 2.5 J per energy point and 90 J / cm2 per point (180 J / cm2 per tooth), applied immediately and 24h after tooth whitening, did not decrease the intensity of tooth sensitivity after office tooth whitening.;Decreased intensity of tooth sensitivity after tooth whitening after photobiomodulation at different times of application, immediately and 24 hours after tooth whitening. | — |
