Summary. Bleaching materials containing hydrogen peroxide have been used successfully for the treatment of discoloured non‐vital teeth; however, their use has occasionally been associated with external root resorption. Some evidence exists that sodium perborate mixed with water is as effective as sodium perborate mixed with hydrogen peroxide.

The Role of Peroxide Based Bleaching Agents in the Induction of Tooth Sensitivity
Revista de Chimie, 2017Tooth whitening is increasingly requested lately due to increased aesthetic demands of patients. The aim of our study was to analyse if there are differences, in terms of tooth sensitivity, between at-home and in-office bleaching agents used in tooth whitening, and also, if a higher concentration of bleaching agents leads to increased the tooth ...

TOXICOLOGICAL CONSIDERATIONS OF TOOTH BLEACHING USING PEROXIDE-CONTAINING AGENTS
The Journal of the American Dental Association, 1997Peroxides have been used for tooth bleaching for more than 100 years. Besides those administered in the dental office, agents for at-home bleaching have become popular. To date, there have been no published significant adverse effects caused by dentist-monitored, at-home bleaching agents.

Acta Odontologica Scandinavica, 2012
It has been shown that bleaching with 35/38% hydrogen peroxides may alter both enamel morphology and mineral content. This study aimed to analyze the morphology and microhardness of enamel bleached with in-office hydrogen peroxides and exposed toremineralizing agents.After recording initial enamel morphology and microhardness, 60 bovine incisors were ...

Stomatologiia, 2003
Pressing problems in bleaching devital teeth are discussed. Bleaching Endoperox and Brilliant were studied in vitro. For evaluating the safety of devital teeth bleaching, the microhardness of dental tissues was evaluated after intra-crown bleaching. The most significant changes in microhardness were observed in the coat dentin area.
