The use of low level laser to reduce pain, inflammation and edema, to promote wound, deeper tissues and nerves healing, and to prevent tissue damage has been known for almost forty years since the invention of lasers. This review will cover some of the proposed cellular mechanisms responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption peaks in the Near Infrared (NIR)). Mitochondria are thought to be a likely site for the initial effects… Expand
Low-Level Laser Therapy (LLLT) in Wound Healing
TLDR
Low-level lasers, also known as LLLT, is an effective tool as an adjuvant for acute/chronic wounds, non-healing ulcers, musculoskeletal disorders, skin rejuvenation, hair growth and pain management. Expand
PHOTOBIOMODULATION, THE PHYSIOLOGICAL RESPONSE OF MUSCULOSKELETAL SYSTEM TO LOW POWER LASERS: A REVIEW
TLDR
This review is intended to understand the physiological actions of lasers and their beneficial effects on musculoskeletal system. Expand
The Need for Increased Attention to Low‐Level Laser Therapy as Treatment for Wounds and Ulcers
TLDR
This review aims to discuss the positive effects of LLLT on skin wounds, diabetic foot ulcers, and burn healing and classified eligible papers into in vivo and in vitro experimental studies and clinical trials that evaluated the use of L LLT as treatments that promote healing. Expand
Approach and potentiality of low level laser therapy in veterinary medicine
TLDR
Different animal pathological conditions could significantly benefit from this therapy, such as acute/chronic muscle-skeletal disorders, dental afflictions, dermatitis, otitis, stomatitis and different kind of skin lesions, as traumatic or post-operative ones. Expand
Proposed Mechanisms of Photobiomodulation or Low-Level Light Therapy
TLDR
After the initial photon absorption events, numerous signaling pathways are activated via reactive oxygen species, cyclic AMP, NO, and Ca2+, leading to activation of transcription factors, which can lead to increased expression of genes related to protein synthesis, cell migration and proliferation,Anti-inflammatory signaling, anti-apoptotic proteins, and antioxidant enzymes. Expand
Could the biological robustness of low level laser therapy (Photobiomodulation) impact its use in the management of mucositis in head and neck cancer patients.
TLDR
An investigational strategy is suggested to assure that LLLT's anti-mucositis efficacy is independent of its possible potential to enhance threatening tumor behaviors and appropriate pre-clinical modeling, short- and long-term follow-up of LLLt-treated patients, and the requirement for consistency of L LLT parameters.

Laser photobiomodulation of pro-inflammatory mediators on Walker Tumor 256 induced rats.
TLDR
The results suggest the evidence 1J-35,7J/cm2 treatment was able to produce cytotoxic effects by generation of ROS causing acute inflammation and thus may be employed as the best energy dose associated with Photodynamic Therapy. Expand
Perspective on Broad-Acting Clinical Physiological Effects of Photobiomodulation.
TLDR
This work has a model for explaining potential therapeusis for applications in functional neurology that include stroke, traumatic brain injury, and neurodegenerative conditions in addition to the currently approved functions in lipolysis, in onychomycosis treatment, and in pain management. Expand
Photobiomodulation with Pulsed and Continuous Wave Near-Infrared Laser (810 nm, Al-Ga-As) Augments Dermal Wound Healing in Immunosuppressed Rats
TLDR
The findings from this study might broaden the current biological mechanism that could be responsible for photobiomodulatory effect mediated through pulsed NIR 810 nm laser (10 Hz) for promoting dermal wound healing in immunosuppressed subjects. Expand
Effect of red light and near infrared laser on the generation of reactive oxygen species in primary dermal fibroblasts.
TLDR
The outcome indicates that the ROS production within biological systems are more dependent on the wavelength of the laser rather than its fluences, for making the best use of the red light and NIR laser in clinics. Expand
