The effect of laser photobiomodulation diode laser (Ga-As) 100 mW on temporomandibular joint anterior disc displacement: preliminary study

ABSTRACT

Background: Superpulsed low-level laser therapy (LLLT) seems to be a good choice as a non-invasive treatment for temporomandibular joint (TMJ) disorders and pain. Objectives. The purpose of this study is to clinically evaluate the effectiveness of splint for treatment of anterior disc displacement with reduction of the TMJ with or without LLLT. Material and methods. This was a prospective experimental study that included 20 female patients with anterior disc displacement with reduction of the TMJ. Patients were randomly assigned into two groups of 10 each. Patients of Group I were subjected to LLLT during four weeks, together with stabilization appliance splint for treatment of anterior disc displacement with reduction of the TMJ. Patients were evaluated before treatment, after six sessions of laser therapy, after 12 sessions of laser therapy, and 1 month after the last session. Patients of Group II were subjected to only stabilization appliance splint. Results. Follow up of maximum mouth opening in mm before and after treatment in Group I showed statistically significant difference with p value<0.001. In concordance, Follow up of visual analog scale (VAS) for pain before and after treatment in Group I showed statistically significant difference with p value<0.001. Comparisons between both groups before and after treatment showed significant improvements in the maximum mouth opening in mm and VAS for pain in Group I. Conclusions. Splint and LLLT in patients with anterior disc displacement with reduction of the TMJ are more effective than splint alone. The application of LLLT is proved to be safe and improves the results of the splint
