|---|---|
| The will initially assess the absolute risk of tooth sensitivity resulting from professional tooth bleaching when associated with homemade. According to a systematic review of clinical studies that evaluated tooth sensitivity when associated with inpatient tooth bleaching when associated with a trained caretaker, 88% of patients had tooth sensitivity at least once during the whitening procedure. To detect a reduction in the primary outcome from 88% in the control group to 68% in the experimental group, a minimum total of 64 volunteers will be required, with a power of 80% and an alpha of 5%. To contemplate possible follow-up losses, another 16 volunteers per group (25%) will be added, totaling 80 volunteers per group | — |
