OTHER

10% carbamide peroxide

The subjects should dispense the bleaching gel at night into the trays (maxillary and mandibular) and to insert them to cover at least the anterior teeth for a period of 4 h per day, over a 2-week period. Both arches should be bleached at the same time. During the period of bleaching, volunteers should receive the same toothpaste used by G1, in other words, without "whitening agents", to standardize their oral hygiene regimen
