title: Dentifrice whitening after professional bleaching.
abstract: Thirty patients whose teeth had been bleached were given one of two toothpastes. One half of the group brushed with a toothpaste containing 10% carbamide peroxide (DW) and the other half with a toothpaste containing 3% hydrogen peroxide (HP) for three months. Color change from baseline was evaluated after 4 weeks and again after 12 weeks, using a shade guide and measured with a colorimeter at baseline. The DW toothpaste was able to stabilize the tooth-lightening effect of the bleaching gel better than the HP toothpaste. The HP product had a lower tooth sensitivity rating.
