Photobiomodulation (sometimes called low-energy laser therapy (LLLT)) is the process by which chromophores selectively absorb low-energy wavelengths and generate cellular signaling phenomena that lead to major biological syntheses1. Photobiomodulation (PBM) has an action on the cellular metabolism of our tissues comparable to photosynthesis in plant cells. Light energy is transferred to the different organs of our cells to stimulate metabolic functions that produce several remarkable clinical effects such as analgesic and anti-inflammatory effects or healing effects. Thanks to its stimulating properties confirmed over the last three decades by numerous studies, PBM has now extended to many fields of medicine, such as endocrinology, neurosurgery, dermatology and dentistry in particular . This type of phototherapy includes a wide range of non-ionizing light sources such as laser, LEDs, and broadband visible light in the visible and near-infrared spectrum at non-thermal doses.
