Effects of carbamide peroxide on dental luting agents
Journal of Endodontics, 1992Vital bleaching of natural dentition using a 10% carbamide peroxide in solution may adversely effect restorative materials such as the luting agents. The purpose of this study is to examine surface structure and alterations of atomic weight percentages of elements in (a) zinc phosphate, (b) glass-ionomer, and (c) resin cements after contact with the ...

Antibacterial activity of 10% carbamide peroxide bleaching agents
Journal of Endodontics, 1996The antibacterial activity of three commercial 10% carbamide peroxide bleaching agents (Nite White, Karisma, and Opalescence) on Streptococcus mutans, Streptococcus mitis, Streptococcus sanguis, Lactobacillus casei, and Lactobacillus acidophilus was examined. Chlorhexidine (0.2%) was used as a positive control.

Remineralization Potential of a Fluoridated Carbamide Peroxide Whitening Gel
Journal of Esthetic and Restorative Dentistry, 2006ABSTRACTPurpose: Little knowledge exists regarding the potential remineralizing benefits of adding fluoride to carbamide peroxide‐based whitening gels. The aim of this project was to evaluate whether a whitening system with fluoride will remineralize previously demineralized enamel.Materials and Methods: Twenty‐four extracted teeth were sectioned ...

Safety Issues When Using a 16% Carbamide Peroxide Whitening Solution
Journal of Esthetic and Restorative Dentistry, 2002ABSTRACT Background: The scientific literature is lacking on the occurrence of side effects and other safety issues when using carbamide peroxide whitening solutions of concentrations greater than 10%. This double‐blind nightguard vital bleaching study compares safety issues when using 16% carbamide peroxide against a placebo or 10% carbamide peroxide (

Vital tooth bleaching for esthetic reasons has gained in popularity during the last few years. However, few studies have investigated the efficacy of daytime bleaching products. The purpose of this double-blind in vivo study was to evaluate the efficacy of 20 percent carbamide peroxide, or CP, and 7.5 percent hydrogen peroxide, or HP, during daytime ...

Higher‐Concentration Carbamide Peroxide Effects on Surface Roughness of Composites
Journal of Esthetic and Restorative Dentistry, 2002ABSTRACT Background: Ten percent carbamide peroxide has been used extensively within the dental profession for the purpose of bleaching teeth. Although this method has been successful, the use of higher‐concentration carbamide peroxides (20–35%) for home bleaching has increased substantially in the past few years.

Penetration of the pulp chamber by carbamide peroxide bleaching agents
Journal of Endodontics, 1992Hydrogen peroxide readily penetrates the pulp chamber of freshly extracted teeth. This study was undertaken to determine whether carbamide peroxide also penetrates the pulp chamber. Freshly extracted teeth were sectioned 2 to 3 mm apical to the cementoenamel junction and the coronal pulpal tissue was removed.
