Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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
