BACKGROUND: Local anesthetics are used to relieve pre- and postoperative pain, acting on both sodium channels and nicotinic acetylcholine receptors (nAChR) at the neuromuscular junction (NMJ). Bupivacaine acts as a non-competitive antagonist and has limitations, such as myotoxicity, neurotoxicity, and inflammation. Low-level laser therapy (LLLT) has anti-inflammatory, regenerative, and analgesic effects. The aim of the present study was to evaluate the effects of a gallium arsenide laser (GaAs) on the morphology of the NMJ and nAChRs after application of bupivacaine in the sternomastoid muscle...

Photobiomodulation (PBM) also known as low-level laser (or light) therapy (LLLT), has been known for almost 50 years but still has not gained widespread acceptance, largely due to uncertainty about the molecular, cellular, and tissular mechanisms of action. However, in recent years, much knowledge has been gained in this area, which will be summarized in this review. One of the most important chromophores is cytochrome c oxidase (unit IV in the mitochondrial respiratory chain), which contains both heme and copper centers and absorbs light into the near-infra-red region...

Increased pain and/or discomfort during chewing, speaking, and swallowing have been commonly reported by patients with Temporomandibular Dysfunction (TMD). Speech-language pathology therapy (orofacial myofunctional therapy - OMT) has been proposed as part of the treatment for this condition; however, it is a modality that should be introduced when the TMD context and the pain are not accentuated, so that they do not prevent or hinder the performance of exercises. The aim of this study was to analyze the effect of OMT on the treatment of patients with TMD, according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), after analgesia with low-level laser therapy (LLLT), regarding orofacial myofunctional conditions (OMC) and the perception of TMD symptoms...
