The purpose of this overview was to review the available literature to determine if there was any evidence that the application of 10% and 15% carbamide peroxide in tooth whitening procedures resulted in tooth (dentine) sensitivity. The conclusions from the review would indicate that tooth whitening with either 10% or 15% carbamide peroxide is an effective and safe treatment when under a dental...

OBJECTIVE Tooth whitening using hydrogen peroxide is a complex process, and there is still some controversy about the roles of pH, temperature, chemical activators, and the use of light irradiation. In this work the basic interactions between whitening agents and stain molecules are studied in simple solutions, thus avoiding the physics of diffusion and light penetration in the tooth to give cl...

This study aimed to assess the efficacy of a 35% hydrogen peroxide--based gel without activation in vitro on three areas of the tooth surface. Vestibular faces of human premolar teeth were darkened, followed by two whitenings at 7-day intervals. The efficacy of whitening was determined in the cervical third, medium third and incisal third of the tooth surface with an Easyshade-Vita spectrophoto...

OBJECTIVE The purpose of this 14-day parallel, double blind clinical trial was to evaluate the tooth whitening efficacy of a 9% hydrogen peroxide gel (Colgate Visible White) relative to a 20% carbamide peroxide gel (Opalescence) positive control. METHODS Forty-six consenting adults were randomly assigned to use one of the two products. All participants had 6 unrestored maxillary anterior teet...

Tooth bleaching has become a popular cosmetic treatment among patients that want to enhance their esthetic appearance. In addition, light-activated bleaching gels have been growing among dental professionals mainly due to the fastening of the whitening procedure and/or therapeutic purposes. Thus, the objective of this case report was to present the bleaching protocol and efficacy of a light-act...

BACKGROUND The authors tested the adjunctive use of light with a 15 percent peroxide gel as a single-visit, in-office tooth whitening system. METHODS Subject (N = 87) with stained (> shade D4, Vita Zahnfabrik, Bad Säckingen, Germany) anterior teeth were randomly assigned to test (peroxide and light), peroxide control (peroxide gel) or light control (placebo gel and light) groups and were trea...
