Photobiomodulation therapy as an additional method for the treatment of temporomandibular disorder patients- a narrative review.

The photobiomodulation therapy (PBMT) is promising additional therapy in the treatment of temporomandibular disorder (TMD). In this regard, the purpose of this narrative review is to give a wide-ranging, objective, and judicious view of the current knowledge on PBMT as an additional TMD treatment modality, with summarised updated information. Although the results of most research studies report improvement of pain in TMD patients, some state that sustainability of absence of pain after PBMT of TMD is of concern. There has been a recent surge in research around the application of lasers for the management of TMD. Nonetheless, the scarcity of scientific clinical studies with structured laser parameters makes it difficult to draw a more concrete conclusion whether lasers in the treatment of TMD are more effective than traditional TMD treatments. In conclusion, since PBMT is becoming an additional treatment of choice for the management of TMD there is a need for more research especially involving clinical studies with better structured laser parameters.
