Full Definition
Myofascial pain dysfunction (MPD) is a common temporomandibular disorder characterized by pain and dysfunction in the muscles of mastication without significant joint pathology. The condition typically presents with muscle tenderness, referred pain, limited mouth opening, and trigger points in the affected muscles. MPD often results from muscle overuse, stress, bruxism, or trauma, and is managed through conservative approaches including physical therapy, occlusal appliances, and stress management.
