Abstract

Introduction: Myofascial Pain Dysfunction Syndrome (MPDS) is one of the most common and important cause of the orofacial pain.Patients with temporomandibular joint and muscle pain gradually learn to live with the symptoms although they have been exposed to a variety of treatments. In some instances the symptoms have been aggravated by the treatment, while other patients have recovered without treatment.Masticatory muscle fatigue and spasm are responsible for the cardinal symptoms of pain, tenderness, clicking, and limited function that characterize the MPD Syndrome.The symptoms of a typical temporomandibular joint dysfunction is classified as (a) pain and its sequelae, (2) clicking and crepitus, and (3) irregularities of mandibular movement.The pain can be unilateral or bilateral with varying degree of pain.Mandibular deviation is a third characteristic often evident in temporomandibularjoint patients. Mandibular deviation, in this instance, refers to the deviation from rest position to mouth wide open is a result of joint malfunction and muscle pain. Various non- surgical and surgical methods are used for the treatment of myofascial pain dysfunction syndrome. Conclusion: Since MPDS consists of variable symptoms, it might be very difficult to provide any definite diagnosis and treatment. Therefore the more the specialists extend their knowledge and information about this disorder, the more they will make the best decision in this regard.
