Comparative Effectiveness of Botulinum Toxin, Low-Level Laser, and Ultrasound for Temporomandibular Disorders.

Botulinum toxin-A effectively relieves pain and joint sounds associated with temporomandibular disorder symptoms, both in the short and long term. Although low-dose laser therapy and ultrasound therapy provided a shorter-term improvement in pain, they significantly improved mouth opening. Hence, in the context of treating temporomandibular disorder, the focus should be on prioritizing the utilization of botulinum toxin-A for pain control, alongside giving precedence to low-dose laser therapy and ultrasound therapy to improve mouth opening.
