Clareamento dental com luz violeta: uma nova realidade para a odontologia

Abstract

The technique of tooth whitening with violet light consists of the application of a concentrated non-ionizing radiation, capable of being absorbed by the dental tissue, not being harmful to the tooth pulp, and having as its main target the dark molecules present on the surface of the dental element. The aim of the present study was to carry out a narrative approach on tooth whitening with violet light through a literature review. The bibliographic survey of this study was done through consultations in the Electronic Databases: LILACS, PubMed and Scielo, selecting studies between 2010 and 2020, in English and Portuguese, that included at least two of the previously selected descriptors. The studies obtained were evaluated in full and after reading the abstracts and file, 48 were used to construct the theoretical framework of the present study. The bleaching with violet light is the most current among the teeth whitening techniques. While in conventional methods the application of gel bleaching agents is used, in this technique exclusively violet light is used, where a visible light band is irradiated that adjusts with the absorption of the peak of darkened molecules, causing a increase in this absorption speeding up its procedural breakdown, fragmenting molecules that do not rearrange themselves. It was observed to be, the violet light capable of breaking darkened pigments on the surface of the dental element in a satisfactory way, showing to be a promising option for use in modern Dentistry deserving more scientific technical studies that justify its indication.
