Tooth bleaching, dentin sensitivity, clinical trial
Conditions
Interventions
All individuals who meet the inclusion criteria (n= 60) will performed at-home bleaching with 10% carbamide peroxide. However, these individuals will be divided into two groups according to the dental
GIB- lightening performed for three weeks. The process of randomizing the individuals in the GI will be carried out by lot, by a team member who is not directly involved in the study.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1. the degree of tooth whitening measured using a spectrophotometer after home bleaching with 10% carbamide peroxide in individuals with aesthetic restorations is lower than that obtained in individuals without restorations. ;Expected outcome 2. the intensity of tooth sensitivity measured using a visual analog scale during home bleaching with 10% carbamide peroxide in individuals with aesthetic restorations is greater than that obtained in individuals without restorations. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome 1. The longevity of home bleaching with 10% carbamide peroxide measured using a spectrophotometer six months after treatment in individuals with aesthetic restorations is less than that obtained in individuals without restorations.;Secondary outcome 2. The longevity of home bleaching with 10% carbamide peroxide measured using a spectrophotometer one year after treatment in individuals with aesthetic restorations is less than that obtained in individuals without restorations. | — |
