Evaluation of therapeutic laser influences on the healing of third-degree burns in rats according to different wavelengths

Abstract

Results of our study showed that using therapeutic lasers with green, blue, red, and infrared wavelengths may accelerate healing process. This trend is more obvious in red and infrared groups especially after acute phase, however, this effect was neither statistically nor clinically significant.

Under the spotlight: mechanisms of photobiomodulation concentrating on blue and green light

“…A second Scopus database search was undertaken to evaluate the effects of green light PBM using the terms described in Figure 3b. An initial search resulted in 236 articles being identified and these articles were subsequently screened for suitability, which then identified 32 relevant articles for further review (18,32,33,64,68,69,79,164,168,171,176,177,186,197,205,209,(212)(213)(214)(215)(216)(217)(218)(219)(220)(221)(222)(223)(224)(225)(226)(227).…”

“…Nevertheless, controversy still surrounds the application of PBM in practice, due to the lack of knowledge concerning how PBM elicits its molecular effects and also a poor understanding of photophysics and radiometric parameters which affect repeatability and reliability (15). The importance of reporting treatment parameters in a more consistent and reliable way has been emphasised in several articles and guidance for reporting radiometric properties has previously been published (15,16) to little or no general avail (17)(18)(19)(20)(21). Indeed, those articles that have provided guidance for reporting radiometric parameters have commonly recommended the consistent reporting of up to ten key radiometric parameters (wavelength, power, irradiation time, beam area (at the skin or culture surface; this is not necessarily the same size as the aperture), radiant energy, radiant exposure, pulse parameters, number of treatments, interval between treatments and anatomical location) (22).…”

Comparative Effect of Low‐intensity Laser Radiation in Green and Red Spectral Regions on Functional Characteristics of Sturgeon Sperm

“…It also follows from the data presented that, when in comparative studies the equality in the energy doses of the acting radiation in red and green spectral regions was provided, the stimulatory effect of radiation in red spectral region was more pronounced (72)(73)(74)(75)(76)(77)(78)(79).…”

Efeitos fotobiomoduladores das luzes vermelha, azul e verde sobre o colágeno durante o processo de cicatrização de queimaduras cutâneas: uma revisão integrativa

“…O grupo tratado confluência 3J/cm²; λ=830nm obteve destaque em relação a proliferação, neovascularização e deposição de colágeno. Fekrazad et al (2017), avaliou o efeito de quatro comprimentos de ondas diferentes: laser verde (G) λ= 532nm; laser azul (B) λ = 405nm; laser vermelho (R) λ= 660nm; laser infravermelho (IR) λ= 810nm; grupo controle (e)= não tratado. Foi observado maior redução da ferida no processo de cicatrização através do laser azul no 7° dia de tratamento, e o laser vermelho no período restante de estudo.…”
