Hydrogen Peroxide Release Kinetics of Four Tooth Whitening Products-In Vitro Study.

Tooth whitening efficacy can be influenced by many variables, among which concentration and application time are two of the most important. This in vitro review sought to determine the initial content and release kinetics of four tooth whitening kits in different concentrations based on the following objectives: To determine HP concentration, Titrations with Cerium Sulphate IV were carried out. The results were published as the mean values and 95% confidence intervals of the percentage of hydrogen peroxide content during release kinetics. The concentration of titrated HP was higher than that indicated by the manufacturers in all tested products. All HP products were launched at least 85% of HP content, as shown by the manufacturers, with the gel containing 10% CP being the first product to be released at 85. 49.

Photothermal-Enhanced Fenton-like Catalytic Activity of Oxygen-Deficient Nanotitania for Efficient and Safe Tooth Whitening.

The growing demand for charming smiles has resulted in the widespreadization of tooth bleaching treatments. While current tooth bleaching solutions with high-concentration hydrogen peroxide are safe, tooth bleaching solutions with high-concentration hydrogen peroxide are safe, but damaging due to the increased risk of enamel loss, tooth sensitivity, and gingival irritation. Among acquired samples, the TiO2-x sample named BT45 was selected due to the highest methylene blue adsorption rate and Fenton-like activity. On some discolored teeth, the BT45/HP+NIR group did much better in tooth whitening than the HP+ NIR group. Excitingly, the same tooth bleaching success as the Opalescence Boost, a tooth bleaching solution containing 40% HP, was obtained by a self-produced bleaching gel based on this novel system, which contains 12% HP. This work demonstrated that the photothermal-enhanced Fenton-like results of the TiO2-x-based system is particularly promising in tooth bleaching applications and can also be expanded to other biomedical applications.
