Abstract

Introduction: Maxillofacial disorders can lead to functional limitation and pain in head and face. Despite the high prevalence of this disorder, quite a few studies have performed in relation to that. The aim of this study was to investigate the effects of He-Ne low power laser (with a wavelength of 632.8nm) in treatment of maxillofacial disorders. Materials and Methods: This study was a randomized clinical trial participating 142 patients with maxillofacial abnormalities, randomly divided to 2 groups of 71experimental and control participants. Background information about the degree of pain was obtained through a questionnaire and VAS (visual analog scale). Experimental and control groups were irradiated with He-Ne low level laser (632.8 nm wavelength, with the average intensity of 2.5 and zero joules per square centimeter) for 12 sessions (3 times a week, each time for 15min). The data related to before and after treatments and the change in percentages were analyzed. Results: before and after treatment, analysis showed significant relief in maxillofacial pain and movement limitations (P=0.013) in the experimental group. Comparisons between groups showed significant improvement in recovery of maxillofacial disorders of experimental against control (P=0.003).Comparing the difference in change percentage in the experimental and control groups was significant (P=0.001). Conclusion: He-Nelow power laser (within the wavelength of 632.8nm) can be considerably helpful to relief maxillofacial disorder’s disability and discomfort. © 2016, Semnan University of Medical Sciences.
