In a longitudinal study we compared clinical data on pain and tenderness and eJcctromyog-raphic recordings of posiural and maximal activity from 37 patients before and after treatment ol functional disorders of the masticatory system. Forty-lhree dental studetits served as controls. Treatment was followed by a concomitant decrease of pain, tenderness and postural activity. Musdc strength in terms of the activity during maximal bite in the iniercuspai position was not altered by treatment, but activation of the right and lefl anterior temporal muscles became more uniform. The relative postural loading of the elevators was assessed as their activity in percent of full effort. Fallowing treatment, loading in patients decreased significantly and became more symmetrical in the anterior temporal muscles. Loading also tended to decrease in the posterior temporal and masseter muscles. However, il still significantly exceeded postural activity in percent of full effort in the controls. Since treatment involved correction of the occlusion we conclude that the intermaxillary conditions of tooth contact during function play a role in the etiology of functional disorders and that the reduction of the relative postural loading of the eie\'ators of the patients due to this treatment contributed to their relief. The relatively high percentage of full efTort displayed as postural activity by the patients even after treatment may explain fluctuation of symptoms and signs offunctional disorders of the masticatory system. It also emphasizes the need for improved methods of treatment lo reduce the probability of recurrence.

“…Roberts and Foglesong [11] proposed that LTM activity also was involved in the ongoing pain of SMP. However, Treede noted that after sympathetic block, stimulation of LTMs did not cause pain [12]. This phenomenon remains puzzling because it begs the question why a sympathetic block would alter the central response to LTM stimulation.…”

Chronic nonodontogenic toothache has been reported in the literature since the 1700s. This problem has followed a similar scenario since those first reports. The patient typically is misdiagnosed and then subjected to multiple unnecessary procedures, ultimately resulting in tooth extractions because of dentists and physicians being unaware of the existence of atypical odontalgia and other types of intraoral neuropathic pain that are treatable without sacrificing the teeth. This paper reviews the medications and procedures used to treat nonodontogenic toothache.

“…The quality of pain is usually a dull ache although it can become sharp and acute (Meklas, 1971;Weinberg, 1980a). Further, the locations of the pain may range from the back of the head and neck posteriorly, to the temporal area superiorly and to the angle of the jaw anteriorly, with the most frequently cited pain location being the area in front of the ear (Bell, 1969;Laskin, 1969;Perry, 1957;Weinberg & Lager, 1980). Fitially, temporal variations of the pain patterns irtay differ.…”

Temporomandibular joint dysfunction syndrome and myofascial pain dysfunction syndrome: a critical review

Temporomandibular joint (TMJ) dysfunction syndrome and myofascial pain dysfunction (MPD) syndrome have been primarily viewed as dental problems and have only recently received close attention by psychologists. The literature reviewed in the present paper reveals that a substantial portion of the population is affected by these disorders. There is, however, a great deal of confusion that exists in relation to the aetiology and treatment of these syndromes. In an attempt to clarify the current understanding of these disorders, the present review first presents a discussion of the symptoms which comprise each of these syndromes and the proposed physiological mechanisms associated with each symptom. Next, the aetiological theories for each of these syndromes are reviewed and critically evaluated. Treatments which have been derived from the theoretical models are then discussed. Finally, methodological considerations involving classification, assessment and treatment issues are presented and future research needs are outlined.
