Myofascial pain syndrome of the TMJ region is not uncommon. It is important to realize that these patients often have a history of TMJ trauma, frequently have positive physical findings of the TMJ, and often have positive roentgenographic findings which continue following successful therapy of myofascial pain syndrome mimicking pain of the TMJ. Because of this, the malady is often diagnosed as TMJ disease, refractory to treatment, rather than correctly as myofascial pain syndrome. Continued investigation of myofascial pain syndrome of the TMJ region is indicated.

Inferior joint space arthrography and measurements of the condylar path provide scientific documentation of derangement of the TMJ disc and condyle. These derangements are described as an anterior displacement of the disk associated with posterior-superior displacement of the condyle when the teeth are closed into the intercuspal position. Clinical studies demonstrate that approximately 70% of a TMJ patient population present with some type or stage of these derangements. These observations have far-reaching implications regarding contemporary dental curriculum, particularly concerning exegesis of the MPD syndrome theory and concepts of dysfunctional dental occlusion.

1. TMJ radiographs made using the head positioner provide a valuable adjunct to diagnosis and treatment planning for patients with MPD syndrome. 2. Where extensive restorative procedures are anticipated, TMJ radiographs can be useful before embarking on a treatment plan and in documenting the postoperative results. 3. Bilateral condylar symmetry is a reasonable objective of extensive restorative dentistry. 4. Radiographic retrusion is more frequently accompanied by signs and symptoms than bilateral condylar symmetry and protrusion.

The oral health of twenth-two patients with a diagnosis of myofascial pain dysfunction syndrome was evaluated. Radiographs, photographs, study casts, visual and digital clinical examinations, hematologic data, blood pressure, and periodontal examinations were used with each patient. A review of the literature indicated a variety of causes for facial pain, including Costen's syndrome, muscle fatique and spasm, occlusion, and psychogenic factors. This study revealed the following trends: (1) The periodontal health of patients with the myofascial pain dysfunction syndrome appears to be better than anticipated. (2) Bruxism accounts for a healthy dental apparatus when other diseases are not present. (3) Groups of muscles, other than the masticatory group, may contribute to the myofascial pain dysfunction syndrome. (4) Patients presented with various ranges of malocclusions and normal occlusions, deep overbites and overjets, complete dentitions, and missing teeth (either equally missing right and left or unequally missing right and left). This article also discusses clinical considerations in the diagnosis of the myofascial pain dysfunction syndrome and offers a practical, physiologic approach to treatment. We conclude that how one uses his mandible is more of a causative factor than the relationships of the teeth.

Previous research has demonstrated a number of conditions, such as sleep disturbance, fatigue, depression, spastic colon and mitral valve prolapse, associated with fibromyalgia. The present report describes additional symptoms and medical conditions that appear to be associated with the syndrome based on a survey of 554 individuals with fibromyalgia compared with a group of 169 controls. Individuals with fibromyalgia self report a greater incidence of bursitis, chondromalacia, constipation, diarrhea, temporomandibular joint dysfunction, vertigo, sinus and thyroid problems. Symptomatic complaints found statistically more prevalent in fibromyalgia patients included concentration problems, sensory symptoms, swollen glands and tinnitus. Other associations occurring with significant increased frequency were chronic cough, coccygeal and pelvic pain, tachycardia and weakness. Our previous report on inheritance patterns in fibromyalgia was reaffirmed with 12% reporting symptomatic children and 25% reporting symptomatic parents. Of the respondents, 70% noted that their symptoms were aggravated by noise, lights, stress, posture and weather.

Orofacial pain can have an inflammatory, neurologic or musculoskeletal cause. Inflammatory diseases include dental abscess, sinusitis, temporal arteritis, sialolithiasis and infections of the parotid gland. Common neurologic diseases that cause facial pain are trigeminal neuralgia, glossopharyngeal neuralgia, paratrigeminal neuralgia and cluster headaches. Musculoskeletal causes include temporomandibular joint syndrome and myofascial pain dysfunction syndrome. A clear understanding of pertinent anatomy and an organized approach to diagnosis will facilitate the evaluation of patients with orofacial pain.

Chewing movement is one of the most important functional and physiological jaw movements, and it is coordinated by the three elements of the functional occlusion system (teeth, TMJs and masticatory muscles). However, the relationship between chewing movement and these elements has not been clarified. The purpose of this study was to investigate the relationship between chewing movement and the activity of the masticatory muscles which directly control jaw movements. 25 subjects with normal stomatognathic function, 5 patients with MPD syndrome (muscle dysfunction group) and 5 patients with unilateral TMJ internal derangement (TMJ dysfunction group) were selected. 6 gums with different hardness were used as the test bolus. Sirognathograph Electromyograph Analysing System was used to simultaneously record chewing movements and electromyograms of the right and left masseter, anterior temporal, posterior temporal and anterior belly of digastric muscles. Using the analysing software which was developed for this study, chewing movements and muscle activities were analysed. The results were as follow; A. In normal subjects 1. Gum hardness influenced durations of the closing and occluding phases, maximum opening and closing speed, opening degree and deviation of opening and closing path. 2. Gum hardness influenced muscle activities except of the time factors of digastric bursts. 3. Durations of the closing and occluding phases were found to be related with the elevator muscle activities. Maximum closing speed was related with the masseter and anterior temporal muscle activities. Deviation of closing path was related with the anterior and posterior temporal muscle activities. B. In abnormal subjects 1. The changes mainly observed in the muscle activities were found to be significantly different between the muscle dysfunction group and normal group. Similarly, the changes mainly observed in the chewing movements were different between the TMJ dysfunction group and normal group. 2. When compared with the relationships in normal subjects, changes were observed in the relationships for closing movement in the muscle dysfunction group. In contrast, changes were observed in the relationships for opening movement in the TMJ dysfunction group. From the results, close relationships were found between chewing movements and muscle activities, and were characteristically influenced by stomatognathic dysfunction.

Chewing movements are accomplished by the harmonious function of the stomatognathic system. Therefore, TMJs play important roles in chewing movements. Recently, significant findings on TMJ abnormalities have been obtained from many studies. However, the relationship between chewing movements and TMJ abnormalities remains unclear. The purpose of this study was to examine how TMJ abnormalities were reflected in chewing movements. Incisor point movements during chewing (chewing pattern) were investigated in 150 abnormal and 25 normal subjects using Sirognathograph Analysing System. Abnormal subjects were composed of 45 patients with anterior disk displacement with reduction (reciprocal click), 20 patients with anterior disk displacement without reduction (closed lock), 50 patients with osteoarthrosis and 35 patients with MPD syndrome. Analysis of condylar movements during chewing were also performed in 9 normal and 20 abnormal subjects. The results were as follow; 1. Subjects with TMJ abnormalities tended to show abnormal chewing patterns when chewing at their non-abnormal sides. 2. TMJ abnormality of each different type tended to show its respective characteristic chewing pattern. 1) Subjects with osteoarthrosis and reciprocal click without condylar posterior dislocation tended to show deviation of the turning point to the non-chewing side, with a convex opening path in the frontal plane and a lack of anteroposterior width in the sagittal plane. This finding was associated with the limitation in movement of the abnormal-side condyle. 2) Subjects with reciprocal click with condylar posterior dislocation tended to show a concave opening path and reversed or cross-over patterns in the frontal and horizontal planes, respectively. This finding was associated with the movement of the abnormal-side condyle in the medio-anterior direction during the initial phase of opening. 3) Subjects with closed lock without condylar posterior dislocation tended to show deviation of the turning point to the non-chewing side, with a concave opening path in the frontal plane and a lack of anteroposterior width in the sagittal plane. This finding was associated with the severe limitation in movement of the abnormal-side condyle. 4) Subjects with closed lock with condylar posterior dislocation characteristically tended to show reversed or cross-over patterns in the horizontal plane. This finding was associated with the movement of the abnormal-side condyle in the medio-anterior direction during the initial phase of opening. However, this movement was smaller than that of the reciprocal click. 3. Subjects with MPD syndrome showed chewing patterns similar to those of normal subjects. From the results, close relationships were found between chewing movements and TMJ abnormalities.

A woman had pain on swallowing and talking when initially seen. Previous diagnoses of glossopharyngeal, neuralgia and myofascial pain dysfunction syndrome had been made. Appropriate treatment for these conditions failed to produce any improvement. Palpation revealed two tender areas bilaterally, overlying the hamulus. Treatment with an injection of 1 ml of dexamethasone (Decadron) 4 mg/ml into each area of tenderness resulted in a dramatic improvement. An anatomic review disclosed the presence of a bursa on the hamulus to protect the tendon of tensor veli palatini. A diagnosis of bursitis was made because of the dramatic improvement in the patient's condition as the result of corticosteroid therapy. Bursitis should therefore be considered in the differential diagnoses of orofacial neuralgias, temporomandibular joint dysfunction, and myofascial pain dysfunction syndrome.
