Effect of a carbamide peroxide paste on gingival inflammation
The Journal of the American Dental Association, 1963Although dental clinicians are acutely aware of the prevalence of periodontal disease among their own patients, the importance of these conditions as a major public health problem is often overlooked. Some measure of the scope of the prob lem is furnished by a 1954 epidemiologi cal study1 which disclosed that 84 per cent of the United States ...

Effects of Bleaching with Carbamide Peroxide Gels on Microhardness of Restoration Materials
Journal of Esthetic and Restorative Dentistry, 2003ABSTRACTThe objective of this in vitro study was to quantitatively assess the effects of bleaching with 10 and 15% carbamide peroxide (CP) on restoration materials by performing superficial micro‐hardness analysis. Acrylic cylindrical containers (4 × 2 mm) were filled with the following restoration products: Charisma (Heraues Kulzer, Vila Santa ...

Effects of phosphoric acid on bovine enamel bleached with carbamide peroxide
European Journal of Oral Sciences, 2008The aim of this study was to measure the demineralization capacity of 37% phosphoric acid on bovine enamel at different time‐points after bleaching with 30% carbamide peroxide. Five, 4 × 4‐mm sections were obtained from the enamel of 10 bovine incisors.

The aim of this study was to assess the durability of bleaching results achieved with (1) 15% carbamide peroxide home bleaching and (2) 38% hydrogen peroxide in-office bleaching. A total of 231 extracted anterior teeth were randomly divided into three groups (n = 77 in each group) with comparable mean baseline L*-values (68.24 ± 0.8): a non-bleached ...

Effect of Whitening Agents Containing Carbamide Peroxide on Cariogenic Bacteria
Journal of Esthetic and Restorative Dentistry, 2000ABSTRACT Purpose: The purpose of this study was to investigate the in vitro antibacterial effects of three different carbamide peroxide products (Nitewhite®, Opalescence®, and Proxigel®) on cariogenic microorganisms (mutans streptococci [MS] and lactobacilli), and to evaluate the effects of a 10% carbamide peroxide solution (Proxigel®) on salivary ...

The Journal of the American Dental Association, 2000
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 ...

In Vitro Penetration of the Pulp Chamber by Three Brands of Carbamide Peroxide
Journal of Esthetic and Restorative Dentistry, 1999Abstract: Purpose: Vital tooth bleaching has become a popular procedure for whitening teeth. Most home bleaching products contain 10% carbamide peroxide. The purpose of this in vitro study was to measure the quantity of hydrogen peroxide that reaches the pulp chamber from three carbamide peroxide products: Opalescence™, Sparkle™, and Rembrandt ...

Bond Strength of Composite Resin to Enamel Bleached with Carbamide Peroxide
Journal of Esthetic and Restorative Dentistry, 1991Bleaching 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 ...

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.

Bleaching primary teeth with 10% carbamide peroxide.
Pediatric dentistry, 2002Bleaching teeth with 10% carbamide peroxide in a custom-fitted tray has been popular for more than 10 years. However, primary teeth are seldom considered for bleaching due to the need for compliance by the child and the natural whiteness of the primary teeth.
