Purposes
Temporomandibular joint disorders (TMD) are the common disorders related to the mandibular joint and nervous systems, which can affect the quality of the patient’s life. The aim of this study is to evaluate the effect of Laser Photobiomodulation Therapy (LPBMT) on different points of the masticatory muscles and temporomandibular joint (TMJ); with digital occlusal splint (DOS) as two conservative treatment options in TMD.
Materials and methods
In this study, 24 TMD patients were randomly divided into three equal groups. The first group A (n = 8) was under treatment of LPBMT on the masticatory muscles and the TMJ. The second group B (n = 8) was under treatment of LPBMT only on the masticatory muscles; and the last group C (n = 8) was a placebo group. All patients received DOS after the LPBMT. Clinical examination was performed before, right after, and 1 month after LPBMT. Subsequently, the patient’s symptoms were evaluated 2 weeks, 1, and 3 months after using DOS. Comparisons of data were analyzed by SPSS software with a significance level of p < 0.05.
Result
In spite of showing no significant group differences (p = 0.110), the results revealed within time all the three groups had a significant improvement in pain intensity and mandibular functions (p < 0.001).
Conclusion
This study showed that a combination of LPBMT and DOS has better clinical results in comparison with DOS alone in the treatment of TMD patients over time.
