he effects of low level laser therapy on the management of chronic idiopathic orofacial pain: trigeminal neuralgia, temporomandibular disorders and burning mouth syndrome

Abstract

Abstract. Aim: To investigate the efficacy of different wavelengths of low level laser therapy (LLLT) in the management of orofacial pain by measuring the pain reduction using visual analogue scale (VAS). Materials and methods: Study involved 20 patients with trigeminal neuralgia (TN), 20 with temporomandibular disorders (TMD) and 40 with burning mouth syndrome (BMS). 50 % of the patients in each syndrome group were treated with 660 nm laser, and other 50 % with 810 nm laser. Orofacial pain was quantified by the VAS. Results: VAS was significantly lower after the application of LLLT, in all subjects and for both applied wavelengths (P < 0.05). Efficacy of 810 nm laser compared to 660 nm laser was significantly higher for all patients and in both the TN and TMD groups (P < 0.001; P = 0.005; P = 0.024). Conclusions: LLLT has proven to be an effective intervention in reducing pain in TN, TMD and BMS patients. Better results can be achieved with higher wavelengths.Key words: burning mouth syndrome; facial pain; lasers; pain measurement; temporomandibular joint disorders; trigeminal neuralgia Sažetak. Cilj: Ispitati učinke različitih valnih duljina mekog lasera (ML) u liječenju orofacijalnog bola mjerenjem prijavljenog bola na vizualno-analognoj skali (VAS). Materijali i metode: U istraživanju je sudjelovalo 20 ispitanika s trigeminalnom neuralgijom (TN), 20 s temporomandibularnim poremećajima (TMP) i 40 sa sindromom pekućih usta (SPU). 50 % ispitanika u svakoj skupini liječeno je laserom 660 nm, a preostalih 50 % laserom 810 nm. Orofacijalni bol određen je prema VAS-u. Rezultati: Nakon primjene ML-a prijavljeni bol bio je značajno manji za sve ispitanike (P < 0,05). Značajno veće smanjenje bola ostvareno je primjenom lasera 810 nm za sve pacijente te za TN i TMP grupu (P < 0,001; P = 0,005; P = 0,024). Zaključci: ML pokazao se učinkovitom metodom smanjenja bola kod TN-a, TMP-a i SPU-a. Bolji rezultati ostvaruju se primjenom veće valne duljine.Ključne riječi: bol lica; laseri; mjerenje bola; poremećaji temporomandibularnog zgloba; sindrom pekućih usta; trigeminalna neuralgija

Effects of photobiomodulation with low‐level laser therapy in burning mouth syndrome: A randomized clinical trial

“…Several studies have been published assessing the efficacy of PBM with LLLT in BMS (Antonió et al, 2017; Arbabi‐Kalati, Bakhshani, & Rasti, 2015; Arduino et al, 2016; Barbosa et al, 2018; Brailo et al., 2013; dos Santos, de Andrade, Nogueira, Leao, & de Freitas, 2015; dos Santos, Carvalho, Leao, Cruz, & Castro, 2011; Sikora, Siber, Vucicevic, Rotim & Matjevic, 2018; Spanemberg, Figueiredo, Cherubini & Salum, 2015; Valenzuela & López‐Jornet, 2017), all of them measured pain with a visual analogue scale (VAS), but only some of them (Arbabi‐Kalati et al., 2015; Arduino et al., 2016; Sikora et al., 2018; Spanemberg, López, de Figueiredo, Cherubini, & Salum, 2015; Valenzuela & López‐Jornet, 2017) measured other quality of life values such as the impact on patients' oral health or indexes of anxiety or depression (Arduino et al., 2016; Spanemberg et al., 2019; Valenzuela & López‐Jornet, 2017). The majority of the studies found positive results, with a decrease in VAS around three points, but in the majority of the studies, no follow‐ups were done.…”

Dose Analysis of Photobiomodulation Therapy in Stomatology

“…Light wavelength influences the deep and superficial target tissues at long and short wavelengths, respectively [ 32 ]. The efficacy of the 810 nm laser is significantly higher than that of the 660 nm laser in treating trigeminal neuralgia and TMD [ 9 ]. The action spectral wavelength ranges from 600 nm to 850 nm for cellular responses, but the inactive region is from 700 nm to 750 nm [ 33 ].…”

“…Nowadays, “photobiomodulation (PBM)” is defined as an accurate and specific term for medical applications [ 5 ], and PBM is recommended for noninvasive, painless, and safe biostimulation. PBM can be applied in many clinical symptoms, such as shoulder pain [ 6 ], acute neck pain [ 7 ], acute low back pain [ 8 ], chronic idiopathic orofacial pain [ 9 ], temporomandibular joint disorder (TMD) [ 10 ], myofacial pain dysfunction syndrome [ 11 ], and dentistry [ 12 , 13 ].…”

Eficácia Do Laser De Baixa Potência Na Disfunção Temporomandibular Em Militares / Efficacy of Low Level Laser for Temporomandibular Disorders in Military

“…Vários autores usaram dispositivos diferentes com comprimentos de onda e dosagens variáveis em suas pesquisas, seguindo uma série de protocolos terapêuticos considerados eficazes para o tratamento da DTM. Mesmo seguindo diferentes protocolos terapêuticos de laser terapia, as condutas escolhidas tanto nesta pesquisa quanto nas pesquisas dos autores citados mostram uma diminuição dos sintomas dolorosos em pacientes com disfunção temporomandibular [23,24,[41][42][43].…”
