Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Absence of postoperative sensitivity in experimental groups 1 and 2, verified by sensitivity tests (thermal and mechanical stimuli), after 4 weeks. It is not expected interference in results of the bleaching treatment in the groups assessed, verified by spectrophotometry, from the observation of the increase in the value of Delta E (indicating the success of the bleaching treatment), after 4 weeks. | — |
Secondary
| Measure | Time frame |
|---|---|
| Absence of postoperative sensitivity in experimental groups 1 and 2, verified by sensitivity tests (thermal and mechanical stimuli), after 1, 2 and 3 weeks. | — |
