Abstract

Background

Temporomandibular Disorders (TMD) refer to a group of symptoms where pain is the most leading cause to demand a treatment by the patient. Light therapies are of great importance at current times due to its biosafety and non-invasive quality when used for the management of TMD symptoms. This study aimed to evaluate the efficacy of red LED light with low-level LASER in treating TMD patients.

Materials and methods

A double-blind randomized clinical study was conducted and included 60 patients along 3 groups (20 for each group) presented with myofascial pain related to TMD. Patients were randomly divided into 3 groups. Group A were managed by applying the LED light device into the trigger points without switching the device on. A red LED light was given to group B for 5 min at the tender muscles. Group C were treated by using low-level LASER therapy for 30 s. Patients were evaluated for any improvements regarding the pain score, presence of trigger points, and trismus along 4 visits (1 week interval between each visit). Any side effects related to the 2 devices were also assessed.

Results

Both group B and C patients showed a statistically significant improvement in the pain value (P < 0.05) at the 3rd and 4th visits when compared to group A. Regarding tenderness, there was a reduction in the number of trigger points in both study groups; however, the results were insignificant in group B. Statistics showed insignificant differences between group B & C patients regarding pain and number of trigger points at all visits (P > 0.05).

Conclusion

Both LED light and LASER therapies could effectively relieve pain associated with myogenic TMD as there were no important differences between their outcomes. However, the biosafety and lower cost of the LED light device compared to the LASER should also be considered.
