In Vitro Penetration of the Pulp Chamber by Three Brands of Carbamide Peroxide

Journal of Esthetic and Restorative Dentistry, 1999
Abstract: 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 ...

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.

Tooth Bleaching by Different Concentrations of Carbamide Peroxide and Hydrogen Peroxide Whitening Strips: An In Vitro Study

Journal of Esthetic and Restorative Dentistry, 2006
To investigate the tooth whitening effects of various concentrations of carbamide peroxide (CP) gels and 6% hydrogen peroxide (HP) whitening strips used on an intrinsic, in vitro stain model in a simulated home-applied bleaching protocol.Extracted third molars were sectioned and stained to Vita shade C4 using a standardized tea solution.

A liquid chromatographic assay for urea in over-the-counter carbamide peroxide products

Journal of Pharmaceutical and Biomedical Analysis, 1994
A liquid chromatographic assay has been developed and validated for determining the amount of urea present in carbamide peroxide formulations. The method employs an interaction CHO-620 carbohydrate column loaded in the Ca+2 form, a flow rate of 0.6 ml min-1, a column temperature of 85 degrees C, and UV detection at 200 nm.
