A efetividade do laser no tratamento da hipersensibilidade dentinária: revisão de literatura

Abstract

The use of laser is becoming more and more frequent in dentistry, the application of laser aims at therapeutic restoration, providing analgesia, healing, stimulation of tissue biomodulation and anti-inflammatory effects, which is why the objective of this work was to conduct a literature review to understand the effectiveness of laser therapy in the treatment of dentinal hypersensitivity, when laser irradiation is used, it promotes photobiomodulation of cell activity, leading to increased odontoblast synthesis in the deposition of tertiary dentin, forming an enormous barrier to thermal stimuli, thus preventing pain stimuli from spreading through the dental pulp. The present study was carried out through a literature review based on scientific articles, published between 1992 and 2020, on the effectiveness of laser in the treatment of hypersensitivity and the effects of low-intensity lasers for the treatment of dentinal hypersensitivity. The data sources consulted were PubMed, Scielo and Google Academic. Through this work it was concluded that the use of lasers in the treatment of dentinal hypersensitivity presents itself as a very effective clinical alternative. Several protocols and laser application dosages, whether high or low power, can be used.
