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.
Although degenerative joint disease is a most common type of arthritis in persons past 40 years of age, and associated with an aging process, this case has been presented as an interesting finding because of the early occurrence. Clinical symptoms, radiographic changes, and microscopic alterations were demonstrated. Conservative therapy was unable to relieve the symptoms and slow the progressive degeneration, and resolution of the subjective complaints was achieved by surgical intervention.
A review of the literature indicates that an allergic response to stainless steel is rare, although nickel is a common allergen and is encountered continually in daily life. An allergic reaction could occur at a most inopportune time. Rational approaches in management of an allergic response to stainless steel appear to be either: (1) wire removal and symptomatic therapy, (2) application of fixation with other substances, or (3) administration of steroids with necessary stainless steel immobilization left in place. The report suggests the need for research to determine the chromium content or chromium-nickel ratio that would eliminate allergic manifestations to the nickel component in wrought or cast base metal dental appliances.
Xeroradiography used with standard cephalometric analysis has proved clinically to be extremely beneficial in the orthodontic and orthognathic evaluation of patients. We have used the negative mode of xeroradiogrpahy routinely and have termed this application xerocephalography. We have described the methods and the equipment and have presented examples of the technique. Xerocephalography provides an improved method which may be universally used in orthodontic and orthognathic treatment.
