Efeitos da luz em sistemas biológicos.

Abstract: ResumoEmbora haja atualmente um extenso emprego de fontes de luz como LASERs (Light Amplification by Stimulated Emission of Radiation) e LEDs (Light Emitting Diodes) em diversas técnicas terapêuticas, as bases científicas de seus efeitos sobre sistemas biológicos ainda é relativamente desconhecida pela comunidade acadêmica. Neste estudo é apresentada uma breve revisão sobre os efeitos da luz em sistemas biológicos. O emprego de fontes de luz de baixa potência, como diodos emissores de luzLEDs, pode propiciar u… Show more

“…Regarding the characteristics of light devices, LASER consists of a resonant optical cavity and different types of active media such as solid, liquid or gaseous materials, in which processes of light generation occur through the passage of an electric current. 77 Potency in the range of 10 -3 to 10 -1 W, wavelength from 300 to 10,600 nm, pulse frequency from 0 (continuous emission) to 5,000 Hz, pulse duration and pulse interval from 1 to 500 milliseconds, total radiation from 10-3000 seconds, intensity between 10 -2 and 10 0 Wcm -1 and dose from 10 -2 to 10 2 Jcm -2 characterized LASER as a low potency device. 78…”

“…A laserterapia de baixa intensidade (Low-level Laser Therapy -LLLT) foi introduzida por Endre Mester no final da década de 60, na Hungria e tem sido utilizada como tratamento primário nas disfunções temporomandibulares (Dias et al 2009;Salmos-Brito et al 2013) É um procedimento não invasivo, fácil de ser empregado, com custo benefício excelente para profissional e paciente, e não possui contraindicações Catão et al (2012). Dentre os efeitos que desempenha destacam-se a aceleração de processos cicatriciais, modulação da inflamação e analgesia, permitindo melhora da abertura bucal e da mastigação (Salmos-Brito et al 2013).…”
