Effectiveness of low-level laser therapy in temporomandibular disorder

Randomized placebo-controlled study to investigate the efficacy of LLLT in TMD. Patients in the treatment group received 15 treatments of 3 J/cm2 at 904nm.  Both groups improved in all measures over the study period. The laser group had significantly better improvement in the number of tender points and all range of motion measures.

Changes in absorbance of monolayer of living cells induced by laser radiation at 633, 670, and 820 nm

Absorption changes in HeLa cells were evaluated from 530-890 nm. Cytochrome c oxidase becomes more oxidized (implying increased cellular oxidative metabolism) at all wavelengths used. This study supports the hypothesis that the mechanism of photobiomodulation is related to the chromophore cytochrome c.

Photobiomodulation in context of new data about multiple roles of ATP

Editorial on mechanisms of photobiomodulation with emphasis on new discoveries that ATP is not only the energy inside cells but also a critical signaling molecule that allows cells and tissues to communicate with one another.
