“Ǫuantum Jump” and Their Effects on the Photo Whitening Technique

Abstract

Recent research on tooth whitening aims to optimize whitening while minimizing its side effects, such as tooth hypersensitivity and damage to the soft and hard tissues of the oral cavity. Various research with methodology using colorimetric and spectrophotometric tests shows that the technique applying violet light, with a wavelength of 408 nm, produced better results than other sources normally used in tooth whitening. Scientific findings prove the results that simultaneously applying dental whitening in the office with transparent/colorless gels and violet LEDs allows the light to interact directly with the pigments, increasing the oxidation effect with the peroxide itself. So, there is a double effect: the photochemical action with the oxidation molecule with the peroxides promoting the optimization of the traditional use of chemical agents. This short communication aims to highlight the advantage of using violet light and provide more physical and chemical information about this whitening process. This is a new technique, without producing heat, roughness or sensitivity, with comfort and safety for the patient and professional. We can conclude that new studies become relevant for the evolution of this technique.
