Blue, Red & NIR (Near-Infrared) light articles

• Effect of 660/850nm LED on the Microcirculation of the Foot: Neurovascular Biphasic Reflex
• Phototherapy can be used to stimulate the healing of chronic ulcers of the lower limb, as it affects healing cells and neurons. In this way the study has sought to know if the heat stimulus of the 660/850nm contact LED is sufficient to trigger the response in the peripheral sympathetic nervous system of normal volunteers.

• PhotoBioModulation (660nm) Therapy Reduces Oxidative Stress and Induces BDNF Expression in the Hippocampus
• PBMT inhibits hippocampal damage induced by oxidative stress and increases the expression of BDNF, which can be used as an alternative to treat a variety of related disorders that lead to nerve damage. Activation and redox homeostasis in neuronal cells may be a notable mechanism of the 660nm PBMT-mediated photobioreactivity.

• Mechanisms and Applications of the Anti-Inflammatory Effects of PhotoBioModulation
• Wound healing, arthritis, muscle recovery, lung inflammation, traumatic brain injury, spinal cord injury, autoimmune diseases, abdominal fat and Achilles tendinopathy, thyroiditis, psoriasis have all been shown to accept PBM treatment well, particularly the 850nm wavelength with regards to muscle preconditioning and better athletic performance.

• Effects of Light Emitting Diode (LED) Therapy at 940 nm on Inflammation Root Resorption in Rats
• The effects of LED therapy at 940nm on periodontal healing, inflammatory ell infiltration and root resorption were analyzed in an experimental model of orthodontic tooth movement in rats. The results suggest that LED therapy improved periodontal tissue repair and decreased inflammation and root resorption after the application of orthodontic force.

• Low Level Laser Therapy Using 940nm LED in the Mandibular Impacted Third Molar Surgery: Double-Blind Randomized Clinical Trial

• In this clinical trial, the effect of intraoral low level laser with a wavelength of 940nm and an energy density of 10 J/cm2 was tested in one session after the surgical operation of the mandibular impacted third molar. The results reveal that LLLT has an alleviate effect on post-surgical pain. Further studies are needed to improve the understanding of the effectiveness of LLLT...

• Intraoral Photobiomodulation-Induced Orthodontic Tooth Alignment: A Preliminary Study
• Under the limitations of this study, the findings suggest that intraoral PBM (850nm) could be used to decrease anterior alignment treatment time, which could consequently decrease full orthodontic treatment time. Further research in the form of a large, randomized trial is needed.

• Different protocols of photobiomodulation therapy of hyposalivation
• The positive effect of the photobiomodulation therapy could be observed 10 days after the completion of the treatment, with better maintained effect of 830 nm wavelength. Thus, indicating a regenerative potential of this type of therapy which should be further investigated and compared with other therapeutic options for hyposalivation.
  

• Effects of 940nm Light-Emitting Diode (LED) on Sciatic Nerve Regeneration in Rats
• The 940nm wavelength has been shown to improve nerve tissue regeneration as well as reducing edema and fibrodegeneration.

• A double-masked, randomized, sham-controlled, single-center study with PBM for the treatment of dry age-related macular degeneration
• These pilot findings support previous reports and suggest the utility of PBM as a safe and effective therapy in subjects with dry age-related macular degeneration.
  

• The Effect of Low-Level Laser Therapy on Salivary Glands in Patients with Xerostomia
• The results of our study indicate that the effects of low-level laser therapy on salivary glands are not only stimulating, but also regenerative to a degree since the glandular response to the same amount of applied laser energy increased linearly over time.

• Antimicrobial blue light inactivation of pathogenic microbes: state of the art
• Antimicrobial blue light in the spectrum of 400-470 nm has demonstrated its intrinsic antimicrobial properties resulting from the presence of endogenous photosensitizing chromophores in pathogenic microbes and subsequently, its promise as a counter-actor of antibiotic resistance.
