Effects of low power laser in maxillofacial disorders recovery

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.
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.
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).
He-Nelow power laser (within the wavelength of 632.8nm) can be considerably helpful to relief maxillofacial disorder’s disability and discomfort.
