Ultrasonic activation of internal bleaching agents
International Endodontic Journal, 2012 AbstractAimTo evaluate the effectiveness of ultrasonic activation of bleaching agents during ex vivo internal bleaching.MethodologyFifty canine human teeth were artificially stained, root filled and divided into five groups (n = 10) that received SP – sodium perborate plus deionized water (control group), CP – 37% carbamide peroxide gel, CPUS – 37 ...

Selection of bleaching agents for dry bleaches
Journal of the American Oil Chemists' Society, 1983AbstractDry bleaches or all‐fabric dry bleaches are increasing in usage (7% +, annually, is quoted) because the consumer is seeking fabric and dye safety coupled with good stain removal. Additionally, the consumer wants a product which requires less sorting of fabrics or colors and aids in the cleansing and stain‐removal action without color, fabric ...

Teeth bleaching using diode laser as an adjunct to a bleaching agent
Journal of Dental Lasers, 2018The use of hydrogen peroxide (H2O2) for conventional bleaching was introduced way back in 1884. Today bleaching products are often found in the form of gels containing various concentrations of carbamide peroxide and H2O2depending on the application and methods. Laser-assisted tooth bleaching has proven faster and efficient results.

Tubular permeability to calcium hydroxide and to bleaching agents
Journal of Endodontics, 1989Recent reports of clinical cases suggest that cervical root resorption may follow bleaching of endodontically treated teeth. Inflammatory root resorption may be arrested by placement of calcium hydroxide into the root canal. The dentinal tubules are assumed to be a possible route of action for both agents.

Effect of Bleaching Agents on the Hardness and Morphology of Enamel
Journal of Esthetic and Restorative Dentistry, 2002ABSTRACT Purpose: The goal of the present laboratory study was to analyze the effect of two home bleaching agents (Opalescence 10%, Ultradent, and Hi‐Lite II, Shofu) as well as the separate solutions of 10% carbamide peroxide primary components (3% hydrogen peroxide and 7% urea) on enamel microhardness and surface morphology.

DNA-Damaging Effects of Dental Bleaching Agents
Bulletin of Experimental Biology and Medicine, 2012We studied DNA-damaging effects of dental bleaching systems containing hydrogen peroxide and/or carbamide peroxide by the "comet assay" (alkaline version). Dental bleaching systems in a hydrogen peroxide concentration range from 0.03 to 30 mM produced a genotoxic effect on isolated HeLa cells in vitro comparable with the effects of pharmacopoeial ...
