Transmissão da energia de três diferentes comprimentos de onda e fontes de luz de um dispositivo disponível comercialmente quando utilizados de maneira isolada ou combinada

Abstract

Photobiomodulation therapy (TFBM) is the term used for the application of low power light, being used for several therapeutic purposes, promoting tissue regeneration, inflammation modulation and pain relief for some years. The intensity of the biological effects depends on cellular metabolism and tissue clinical condition before irradiation. TFBM is applied over a length range of 600 to 1000 nm. Most studies are carried out in vitro or in vivo on human or animal skin and eventually combined with other types of tissue, with immediate penetration depth measures and energy loss. Studies comparing the use of these types of devices are still lacking, in addition to research related to irradiation time. The study of light transmission from a TFBM device with different light sources and three wavelengths (640, 875 and 905 nm) was carried out in an isolated or combined manner during the times of 1 second, 10, 30, 60, 90, 120 and 150 seconds through the mouse skin. According to the present study, the combination of different wavelengths and light sources was able to deliver a greater amount of energy when applied simultaneously in relation to the isolated application. Suggesting that the use of TFBM in a combined way is more efficient to reach different types of tissues. However, it is necessary that clinical studies are carried out using parameters similar to those applied in this study, so that efficient protocols are created.
