Interventions
Co-participatory randomized clinical trial in humans. Eighty-four (84) research subjects - 42 residents in the State of Rio de Janeiro and 42 in the State of Sergipe - with a minimum age of 18 years o
Experimental Group 2 - single application for 40 minutes
Control Group - two applications of the bleaching gel for 20 minutes each, in the same appointment, one after the other. A randomization list will be created by an operator that will not participate i

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The application of the bleaching gel for a reduced time (single application of 20 min), will promote less sensitivity than the control group (2 applications of 20 min each), but also less bleaching potential. The data will be evaluated using statistical analysis | — |
Secondary
| Measure | Time frame |
|---|---|
| The application of the bleaching gel for 40 minutes directly, and without exchange, will promote color alteration and sensitivity level similar to the control group (2 applications of 20 minutes each). The data will be evaluated through statistical analysis | — |
