Bond strength of composite resin to enamel bleached with carbamide peroxide.
TLDR
The results of this study indicate that carbamide peroxide bleaching reduces the shear bond strength of composite to etched enamel, however, removal of surface enamel restores bond strengths to normal levels.Abstract:
Bleaching with 35 percent hydrogen peroxide causes enamel surface changes, which result in lower bond strengths of composite resin. Although a previous SEM study showed that home bleaching with 10 percent carbamide peroxide does not cause such surface changes, the results of our study indicate that carbamide peroxide bleaching reduces the shear bond strength of composite to etched enamel. Removal of surface enamel, however, restores bond strengths to normal levels.read more

History, safety, and effectiveness of current bleaching techniques and applications of the nightguard vital bleaching technique.
TL;DR: This article reviews the literature on the use of hydrogen peroxide in three professionally administered bleaching techniques from historical, technique, and safety viewpoints to discuss the advantages and disadvantages of different bleaching options.

Nonvital Tooth Bleaching: A Review of the Literature and Clinical Procedures
TL;DR: There is a deficiency of evidence-based science in the literature that addresses the prognosis of bleached nonvital teeth, so it is important to always be aware of the possible complications and risks that are associated with the different bleaching techniques.
Journal ArticleDOI
Effect of bleaching on restorative materials and restorations—a systematic review
TL;DR: Advice is provided based on the current literature to minimize the impact of bleaching therapies on restorative materials and restorations.
Journal ArticleDOI
The effects of peroxide bleaching on composite to enamel bond strength
TL;DR: Polymerization inhibition of the resin bonding agent is the likely mechanism for the effects of the bleaching on bond strength.
Journal ArticleDOI
Review of the current status of tooth whitening with the walking bleach technique.
TL;DR: This review discusses how the walking bleach technique can lead to successful whitening of non-vital root-filled teeth without the risks of side-effects and provides advice based on the current literature.

Nightguard vital bleaching: effects on enamel surface texture and diffusion.
TL;DR: There was no difference in color between the treated and control areas; the color-changing effects apparently extend to portions of the tooth not in direct contact with the solution.

Preliminary Surface Analysis of Etched, Bleached, and Normal Bovine Enamel
TL;DR: Results suggest that the reported decrease in the adhesive bond strength of resin to 35% H 2O2-treated enamel is not caused by a change in the elemental composition of treated enamel surfaces, and that an organic-rich layer, unaffected by acid-etching, may be present on the unground un-pumiced surface of young bovine incisors.

Bleaching tetracycline-stained vital teeth☆
TL;DR: Six patients with cystic fibrosis, ranging in age from 6 to 18 years, were selected at random for a preliminary study of a technique for bleaching vital teeth which were stained by tetracycline administration, and there was significant esthetic improvement in five of the six patients.

A practical method of bleaching tetracycline-stained teeth
TL;DR: It is demonstrated that a good esthetic result can be achieved by bleaching tetracycline-stained teeth by heating 35 per cent hydrogen peroxide to approximately 120° F. for 20 minutes.
