O uso do laser de baixa potência no tratamento da disfunção temporomandibular: revisão de literatura

Abstract

Temporomandibular disorder (TMD) is a multifactorial syndrome that affects bones and muscles associated with the temporomandibular joint (TMJ), presents physical etiology from disorders of the TMJ itself, muscle dysfunctions or even malocclusions or biopsychosocial etiology from anxiety problems, stress and depression, treatment can be performed through laser photobiomodulation (FTBM), transcutaneous electrical neurostimulation (TENS), physiotherapy, acupuncture, among others. Laser is an American acronym that means, Light amplification by stimulated emission of radiation. This light, when irradiated in damaged tissues, interacts with organelles sensitive called chromophores present in mitochondria, this interaction results in cell excitation promoting numerous tissue benefits. Low Level Laser Therapy (LLLT) is used in the treatment of tissues under oxidative stress due to its analgesic, anti-inflammatory, tissue repair and muscle relaxant properties. This review aimed to analyze the use of LLLT in the treatment of TMD, through a survey of the scientific literature. The strategy used for this work was the study survey, in electronic databases, such as: PubMed (Public Medline), Scielo (Scientific Electronic Library Online) and VHL (Virtual Health Library) in the period from 2018 to 2023. According to the researched articles, it could be observed that LLLT was able to promote relief of signs and symptoms in TMD.
