The question of whether photobiomodulation should be used as a drug equivalent arose in my mind after listening to presentations at the recent conference of the World Association for Laser Therapy (WALT)-2012 (Gold Cost City, Australia), and later at home when searching MEDLINE for the years 2009–2012. Photobiomodulation (earlier terms: low level laser therapy, LLLT, laser biostimulation) has been used in clinical practice for >40 years by now, and its action mechanisms on cellular and… 
Photobiomodulation Therapy in Oral Medicine: A Guide for the Practitioner with Focus on New Possible Protocols.
The aim of the review is to describe the possible applications of PBM in oral medicine, giving practitioners simple guide for practice together with the information of a new treatment possibility "at home" performed by the patient himself under supervision.

There is an urgent need in the wound care community to develop optimal clinical protocols for use based on well-designed, rigorous clinical research studies, and a lack of consensus on standardized treatment parameters such as wavelengths, dose, and therapeutic outcomes in the reviewed studies.
Photobiomodulation of Human Fibroblasts and Keratinocytes with Blue Light: Implications in Wound Healing
It is observed that the blue LED light can be used to modulate metabolism and proliferation of human fibroblasts, and the effects in wound healing are particularly evident when studying the fibro Blasts and keratinocytes co-cultures.
The Rationale for Photobiomodulation Therapy of Vaginal Tissue for Treatment of Genitourinary Syndrome of Menopause: An Analysis of Its Mechanism of Action, and Current Clinical Outcomes

Perspective on Broad-Acting Clinical Physiological Effects of Photobiomodulation.
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.
Photobiomodulation with non-thermal lasers: Mechanisms of action and therapeutic uses in dermatology and aesthetic medicine
Although present studies have demonstrated the safety and efficacy of non-thermal laser for body sculpting, cellulite reduction and onychomycosis treatment, studies demonstrating the efficacy ofNon-Thermal laser as a stand-alone procedure are still inadequate.
Light-Based Devices for Wound Healing
The goal of this review is to provide a broad overview of light-based treatments that have shown effectiveness in enhancing various aspects of wound healing, examine the drawbacks that have impeded
"Quantum Leap" in Photobiomodulation Therapy Ushers in a New Generation of Light-Based Treatments for Cancer and Other Complex Diseases: Perspective and Mini-Review.
Studies support what is described as a paradigm shift or "quantum leap" in the understanding and use of light and its interaction with water and other relevant photo-cceptors to restore physiologic function.
Assessing the impact of low level laser therapy (LLLT) on biological systems: a review
It is suggested that a change in approach is required to understand how to exploit the potential therapeutic modality of lasers whilst minimizing its possible detrimental effects.
Evaluation of photobiomodulation in salivary production of patients with xerostomy induced by anti-hypertensive drugs
A randomized, placebo-controlled, blind clinical protocol that aims to analyze the impact of phobiomodulation (PBM) on salivary glands of patients with antihypertensive drug induced xerostomia to determine the effectiveness of photodynamic therapy regarding the reduction of xerstomia in older adults using antihyertensive drugs.

The role of ATP as a signaling molecule provides a new basis for explaining the versatility of low-power laser effects and broadening the understanding of universality phenomenon of LLLT.
Inhibitory effects of laser irradiation on peripheral mammalian nerves and relevance to analgesic effects: a systematic review.
A range of laser-induced inhibitory effects in diverse peripheral nerve models, which may reduce acute pain by direct inhibition of peripheral nociceptors, are identified and may result in long-term depression of pain.
Taking a light approach to treating acute ischemic stroke patients: Transcranial near-infrared laser therapy translational science
Transcranial near-infrared laser therapy, which may promote functional and behavioral recovery via a mitochondrial mechanism and by enhancing cerebral blood flow, may eventually be established as an Food and Drug Administration (FDA)-approved treatment for stroke.
Low-level laser therapy: a useful technique for enhancing the proliferation of various cultured cells
This review suggests that an energy density value of 0.5 to 4.0 J/cm2 and a visible spectrum ranging from 600 to 700 nm of LLLT are very helpful in enhancing the proliferation rate of various cell lines.
Low-level laser irradiation alters cardiac cytokine expression following acute myocardial infarction: a potential mechanism for laser therapy.
Although LLLI did not improve the damaged heart function, it did reduce the infarct area expansion and reveal a potential novel mechanism for applying laser therapy to the treatment of heart disease.
Collagen production in diabetic wounded fibroblasts in response to low-intensity laser irradiation at 660 nm.
Diabetic wounded cells irradiated with 5 J/cm(2) at 660 nm showed a significant increase in cell migration, viability, proliferation, and collagen content, and LILI stimulates Col-I synthesis in diabetic wound healing in vitro at 660nm.
Effect of equal daily doses achieved by different power densities of low-level laser therapy at 635 nm on open skin wound healing in normal and corticosteroid-treated rats
LLLT, by the method used, improved wound healing in the non-steroid laser-treated rats, but it was useless after corticosteroid treatment.
