High‐concentrated carbamide peroxide bleaching agents effects on enamel surface

Journal of Oral Rehabilitation, 2004
summary  Concern has been expressed regarding the adverse effects of peroxide‐containing tooth bleaching agents on enamel surface. This study examined enamel average surface roughness before (baseline) and after an in‐office bleaching protocol and investigated the influence of high concentrations of carbamide peroxide gels on its surface staining and ...

Effect of carbamide peroxide and hydrogen peroxide on enamel surface: an in vitro study

Clinical Oral Investigations, 2010
The aim of the study was to investigate changes in the micromorphologyl and microhardness of the enamel surface after bleaching with two different concentrations of hydrogen peroxide (HP) and carbamide peroxide (CP). Bovine enamel samples were embedded in resin blocks, and polished.

Nano-hydroxyapatite-induced remineralization of artificial white spot lesions after bleaching treatment with 10% carbamide peroxide.

Journal of Esthetic and Restorative Dentistry, 2022
OBJECTIVE To assessed in vitro the effect of nanohydroxyapatite (n-HA) to improve the aesthetic appearance and microhardness of white spot lesions (WSL) when associated with a low-concentration bleaching agent (carbamide peroxide-CP10%).

Demineralization effects of 10 percent carbamide peroxide

Journal of Dentistry, 1996
The purpose of this in vitro study was to measure the amount of calcium lost from enamel exposed to a 10% carbamide peroxide solution.Nine teeth (3 incisors, 2 premolars, 4 molars) were sectioned to serve as paired test and control specimens. Each tooth half was coated with wax, leaving a uniform 3 mm x 4 mm window of exposed enamel.

Radicular peroxide penetration from carbamide peroxide gels during intracoronal bleaching

International Endodontic Journal, 2008
AbstractAim  To evaluate and compare radicular peroxide diffusion from different concentrations of carbamide peroxide bleaching gels.Methodology  Fifty maxillary premolar teeth were separated into five groups (n = 10). Standardized endodontic access cavities were prepared in the occlusal surfaces, and the root canals were prepared using a step back ...

Evaluating Tooth Color Change from Carbamide Peroxide Gel

The Journal of the American Dental Association, 1993
A double-blind experiment assessed the efficacy, longevity and safety of a tooth whitener in young adults. Significant color changes occurred after active treatment but were substantially reversed after one week. No permanent changes were found in either pulpal or gingival health.
