Epidemiologic and clinical studies have established an association between headache and functional disturbances of the stomatognathic system. However, little attention has been paid to the diagnosis of the type of headache in question. In the present study the clinical signs and subjective symptoms of temporomandibular joint (TMJ) dysfunction were investigated in 39 patients (3 1 females, 8 males) with muscle contraction headaches. These headaches were defined by routme neurologic examination, skull radiograms, and electroencephalographic (EEG) studies. Subjective TMJ dysfunction symptoms were reported by 36 patients (92%). The most commonly reported symptoms were TMJ clicking (64%) and fatigue of the jaw muscles (5 1%). One third of the patients were conscious of clenching or bruxism. All patients had one or more signs of TMJ dysfunction. The most frequent findings were tenderness to palpation of the lateral pterygoid muscle (95%) and the attachment of the temporal muscle (67%). TMJs were tender to palpation on the dorsal surface in 15 patients (38%) and on the lateral surface in 25 patients (64%). TMJ sounds were recorded with a stethoscope in 19 patients (49%). Disk displacement (unilateral or bilateral lock) was present in two patients and anterior disk displacement (reciprocal clicking) in five patients. The frequency of anamnestic joint clicking, fatigue, bruxism, and neck pain in this group exceeded that reported by Rieder, Martinoff, and Wilson a year earlier for a large group of patients (J. Prosthet. Dent. 50: 8188, 1983). It appears that neurologically diagnosed muscle contraction headaches are indistinguishable in practice from headaches caused by TMJ dysfunction.
In companion articles in the same issue, the authors report on TMJ dysfunction in patients with migraine headaches only, and on the correlation of the frequency and intensity of headache in TMJ dysfunction patients. Patients with migraine headaches reported symptoms and displayed clinical signs of TMJ dysfunction. The findings of the present studies should provide impetus for the treatment of TMJ dysfunction in headache patients. T. M. Graber

This study from the University of Zurich is based on 92 sets of study models and 92 cephalometric tracings of 23 patients treated by the multibanded edgewise technique. Both the models and the cephalograms were procured at specific intervals (that is, at the beginning of active treatment, at the end of active treatment, at the end of retention, and at the final checkup). The main objective of the study was to determine location and degree of posttreatment change. The patients in the sample were classified according to Angle malocclusion category, extraction, and nonextraction cases. The relapse differences between the groups were noted and reported. The following changes were recorded: mandibular dentition crowding, reduction of intercanine width, and overjet and overbite relapse. Depth of the curve of Spee, which was reduced during treatment, remained unchanged. Because of the upward and forward rotational growth of the mandible, the mandibular plane angle decreased after treatment. The ANB angle, which was reduced during treatment, did not relapse. The only differences in relapse between the groups were seen in the overbite and maxillary incisor inclinations. As might be expected, the deeper the overbite at the beginning of treatment (in Class II malocclusions particularly) the greater the relapse potential. T. M. Graber
