Primary Outcome Measures

Name	Time	Method
Tooth Sensitivity - evaluate and compare the intensity of tooth sensitivity using the Numerical Rating Scale (NRS) and Visual Analog Scale (VAS). Assess the absolute risk of tooth sensitivity using the NRS and VAS.

Secondary Outcome Measures

Name	Time	Method
Efficacy - to evaluate the effectiveness of combined tooth bleaching by evaluating color changes using a Digital Spectrophotometer (VITA Easyshade) using the CIE-L*a*b* system and CIEDE2000, Whiteness Index for Dentistry - WID, scale VITA Classical and VITA Bleachedguide 3D-MASTER scale.;Quality of Life - to evaluate the impact of associated tooth bleaching on quality of life-related to oral health using the Brazilian version of the Oral Health Impact Profile – Aesthetic Questionnaire (OHIP-Aes-Braz).
