Photobiomodulation (PBM) also known as low-level level laser therapy is the use of red and near-infrared light to stimulate healing, relieve pain, and reduce inflammation. The primary chromophores have been identified as cytochrome c oxidase in mitochondria, and calcium ion channels (possibly mediated by light absorption by opsins). Secondary effects of photon absorption include increases in AT...
I N T R O D U C T I O N Lasers have been used for oral soft tissue dental procedures for more than 30 years, and have been researched since the middle 1960s. Their reported benefits over conventional treatment modalities include: reducing numbers of appointments, reducing stress, improving visibility, improving patient comfort, and reducing complications. Critics have commented that most of the...
High power lasers are used extensively in medicine while lower power applications are popular for optical imaging, optogenetics, skin rejuvenation and a therapeutic modality termed photobiomodulation (PBM). This study addresses the therapeutic dose limits, biological safety and molecular pathway of near-infrared (NIR) laser phototoxicity. Increased erythema and tissue damage were noted in mice ...
BACKGROUND AND OBJECTIVES Photobiomodulation (PBM) has been proposed as a potential therapy for spinal cord injury (SCI). We aimed to demonstrate that 810 nm light can penetrate deep into the body and promote neuronal regeneration and functional recovery. STUDY DESIGN/MATERIALS AND METHODS Adult rats underwent a T9 dorsal hemisection, followed by treatment with an 810 nm, 150 mW diode laser (...
