Aim: The aim of this study was to evaluate the influence of temperature on the bleaching efficacy of hydrogen peroxide on chromogenic solutions from wine and tobacco. Methods: Inside optical glass cuvette, equal amounts of chromogenic solution (wine or tobacco), hydrogen peroxide 60% and ultra-pure water were mixed. Initial color readings were performed with a reflectance spectrophotometer immediately after mixing. Samples of the solutions were subjected to predetermined temperatures (5, 10, 15…

Effect of halogen light irradiation on hydrogen peroxide bleaching: an in vitro study.

In-office bleaching was effective for tooth whitening and the involvement of halogen light was beneficial for the immediate whitening effect but had little impact on the long-term Whitening effect.

Efficacy of tooth bleaching with and without light activation and its effect on the pulp temperature: an in vitro study

Light activation of the bleaching agent seems not to be beneficial compared to bleaching without light activation, concerning the colour stability up to 3 months after bleaching and the pulp temperature caused during the Bleaching procedure.

Analysis of shade, temperature and hydrogen peroxide concentration during dental bleaching: in vitro study with the KTP and diode lasers

The KTP laser appears to provide better results with less dangerous thermal increases than the diode laser, and this might call into question most of the literature affirming that the action of laser bleaching is by increasing the gel temperature and, consequently, the speed of the redox reaction.

Clinical evaluation of a 35% hydrogen peroxide in-office whitening system.

It is indicated that light-curing is optional with this 35% tooth whitening system.
