Treatment of dentin hypersensitivity with laser: systematic review

Abstract

BACKGROUND AND OBJECTIVES: Dentin hypersensitivity is an exacerbated response to a stimulus, causing acute and short-term pain. Over the years, several treatments for dentin hypersensitivity have emerged, including laser therapy. Thus, the objective of this work was to carry out a review about the available devices and the existing procedures of laser therapy in the treatment of dentin hypersensitivity. CONTENTS: A systematic review of studies published from 2016 to 2020 was carried out through bibliographic search in the electronic databases Pubmed and the Biblioteca Virtual em Saúde -(Virtual Health Library), using the following descriptors: "Laser" And "Dentin Hypersensitivity". Of the total of 51 articles found in the search, 14 were eligible for a review. There was an evaluation of the possible risks of bias for each of the articles included. CONCLUSION: As a result, a variety of devices available on the market and different protocols that prove to be effective for the treatment of dentin hypersensitivity when compared to the initial pain situation (baseline) were found. When laser treatment is compared with other existing therapies, it's not so clear which would be the most effective, due to the wide variety of study methodologies. However, an association of therapies that act in the two mechanisms of pain interception (neural and blocker) seems to be an appropriate conduct in the control of dentin hypersensitivity, and this combination can happen through physical Treatment of dentin hypersensitivity with laser: systematic reviewTratamento da hipersensibilidade dentinária com laser: revisão sistemática

Phototherapy Using Er,Cr:YSGG Laser as a Definitive Treatment for Dentin Hypersensitivity: A Systematic Review

“…The results of this systematic review are consistent with those from a previous meta-analysis, 29 , 32 which reported that lasers were more efficient than placebo for DH treatment. Similarly, Rezazadeh et al’s systematic review reported that a high-level laser was effective for the treatment and prevention of DH.…”

“… 33 Additionally, several systematic reviews report that the Er,Cr:YSGG laser is effective in the treatment of DH and maintaining its efficacy over time. 27 , 29 , 34 However, the results of this systematic review are in contrast to those from that conducted by Sgolastra et al, 35 in which the evidence of the effectiveness of laser treatment was weak and the placebo effect could not be ruled out. Notably, only 3 RCTs were included in that review.…”

“… 27 , 28 Er, Cr:YSGG is among the most used lasers in DH treatment and have shown a good result in relieving pain caused by DH. 29 The efficacy of Er,Cr:YSGG laser in treating DH is owed to the increased absorption of its wavelengths (2780 nm) by water, which can evaporate dentinal fluid from the exposed tubules. 17 Thus, the flow movement is reduced, and insoluble salts are formed that seal the dentinal tubules.…”

Enfermagem em Evidência - Volume 1

“…Existem dois tipos de laser, o de alta frequência e de baixa frequência. Os lasers de baixa intensidade são usados como agentes terapêuticos após a terapia convencional e possuem propriedades antiinflamatórias, analgésicas e cicatrizantes que podem reduzir o uso de tratamento farmacologico (MENDES et al, 2021).…”

Experiência Formativa De Uma Professora Alfabetizadora E Implicações Ao Ensino De Alunos Com Deficiência

“…Essa nova realidade demonstra também que, cada vez mais, professores estarão se deparando com a tarefa de ensinar os alunos com deficiência na Educação Básica e no Ensino Superior, ao passo que evoluem os problemas, desencontros e desencantos, dentro das escolas, oriundos das contradições entre a perspectiva da educação inclusiva garantida nos marcos regulatórios e as condições de efetivá-la. Nesse contexto, ganham relevo as questões relacionadas à formação dos professores, no que concerne a articulação entre o comum e o específico, entre formação inicial e continuada, entre teoria e prática (OLIVEIRA, 2010;MENDES;CIA;CABRAL, 2015;FALCÃO, 2020), além dos problemas com financiamento, mesmo com definições em marcos legais importantes.…”
