Effect of bleaching agents on the microhardness of tooth-colored restorative materials
The Journal of Prosthetic Dentistry, 2006There is no consensus concerning the effect of bleaching gels on microhardness of restorative materials. Information about the effect of whitening strips on microhardness of restorative materials is also limited.The purpose of this study was to evaluate the effect of a bleaching gel and a whitening strip on the microhardness of 3 tooth-colored ...

Effect of tooth bleaching agents on protein content and mechanical properties of dental enamel
Acta Biomaterialia, 2015This study investigated the effect of two bleaching agents, 16% carbamide peroxide (CP) and 35% hydrogen peroxide (HP), on the mechanical properties and protein content of human enamel from freshly extracted teeth. The protein components of control and treated enamel were extracted and examined on sodium dodecyl sulfate polyacrylamide gel ...

Assessing the Effect of a Desensitizing Agent Used Before In-office Tooth Bleaching
Journal of the American Dental Association, 2009Tooth sensitivity has been reported with in-office tooth bleaching. The authors conducted a study to evaluate whether the use of a desensitizing agent before in-office bleaching decreased this sensitivity.Before in-office bleaching with a 35 percent hydrogen peroxide gel (three applications of 15 minutes each), clinicians applied a placebo gel on the ...

Calcium Phosphate Microspheres as a Delivery Vehicle for Tooth-Bleaching Agents
Journal of Dental Research, 2017Bleaching of vital teeth has become common practice in cosmetic dentistry today. Tooth sensitivity and demineralization of the enamel are, however, common side effects associated with hydrogen and carbamide peroxide bleaching. This study investigated if calcium phosphate microspheres, which have remineralizing properties, could be used as an additive ...

Summary. Bleaching materials containing hydrogen peroxide have been used successfully for the treatment of discoloured non‐vital teeth; however, their use has occasionally been associated with external root resorption. Some evidence exists that sodium perborate mixed with water is as effective as sodium perborate mixed with hydrogen peroxide.
