Clinical and Experimental Study of Gaalas Phototherapy for Tемрoromandibular Disorders

Abstract

Summary. The objective of this study was to test the clinical effectiveness of the gallium-aluminum-arsenide laser (GaAlAs; 785 nm) and superluminiscent diodes (633 nm) phototherapy (MedX 1100 device) for the treatment of patients with temporomandibular disorders and myofascial pain syndrome. The results demonstrated a positive effect in pain relief. A signifi cant reduction (p < 0.05) in the level of pain was observed for the temporomandibular joint and for the masseter muscles using paired samples t-test and Wilcoxon signed rank test. The experimental study on pork muscle samples showed that a) the main part of laser radiation is absorbed by the tissue in thin layer of 3-4 mm, b) in the spectral region 650-950 nm the intensity of light penetration is about 0.2-0.25 percent of the initial light intensity.

GaAlAs phototherapy for tension and compression related temporomandibular disorders

“…For the purpose of the study were selected the etiology -related questions from DC/TMD: Symptom Questionnaire, Graded Chronic Pain Scale (v2), Patient Health Questionnarie-9, GAD-7, Oral Behaviors Checklist -for the presence of bruxism, stress induced parafunctions; other specific questions like the presence of iatrogenic trauma, etc. (17).…”

“…Former research have reviewed the subject on single laser therapy for definite muscle groups or TMJ. Up till now the combined cold laser therapy has been researched in the context of seven of the DC/TMD diagnosis with high specificity and sensibility (17,18,24). However, from a clinical point of view the evaluation of any kind of treatment of bigger diagnostic subgroups that are based on etiopathogenetic factors involved is very expedient and in a total agreement with DC/ TMD methodology.…”

The use of photobiomodulation for the muscles of head and neck: an integrative review

“…Most of the studies included in this integrative review presented positive results for pain management in the head and neck muscles (1,6,11,13,15,(17)(18)(19)(23)(24)(25)(26)(27)(28)(29)(30)(32)(33)(34)(35)(38)(39)(40)42,44,46,(50)(51)(52)(53)(54)(55)(56)(57) . For pain, there is evidence that PBM blocks the axonal transport of thin nerves, resulting in decreased mitochondrial membrane potential with a consequent decrease in the available ATP necessary for nerve function (11,62) .…”
