Inclusion Criteria

Provide written and signed consent; Complete the vaccination schedule for COVID-19; Agree NOT to participate in another clinical trial during the course of the project; Present good general and oral health; Have not undergone dental bleaching in the last 3 years or have undergone it in the last 3 years, but have teeth darker than color A2; Having vital teeth in question (Positive response to the cold sensitivity test, absence of signs or symptoms of pulpal or periapical pathology, absence of radiographic signs of periapical pathology); No edentulous space between the premolars of each arch (upper and lower); Upper incisors must be classified as A2 or darker in color and free of caries and/or restoration; Age (over 18 and under 30); Being in treatment or other activities in FOP, not generating the need for exclusive visits for the research

Exclusion Criteria

Participating in another clinical trial; Presenting with a pre-existing medical condition (pregnant, lactating, smoking, or routine use of alcohol) or oral condition (non-vital teeth, dental caries in the region where the bleaching will be performed, need for endodontics, orthodontics or periodontal treatment and poor oral hygiene) that the investigator/examiner deems could put the individual at risk during the study; Have an adverse reaction to the materials used or a medical or dental history that could interfere with the progress of the study; Unable to attend appointments; The teeth in question have cracks or other defects that may increase the risk of pulpal toxicity; Is under treatment or needs periodontal treatment or caries; Have teeth lighter than color A2; Have extensive restorations on the teeth that will receive bleaching; Patient has a history of tooth sensitivity

Primary Outcome Measures

Name	Time	Method
Evaluate promoted color change. It will be verified through a comparison between the tooth color before whitening and the tooth color after whitening. The measurement will be performed using a manual spectrophotometer (Easyshade) and a standardized visual scale - Vita Scale. The color change calculation will be performed using the final-initial values. Data will be transformed into delta WID and delta E values (CIEDE 2000)
