The aim of this study was to determine the prevalence of pain that is related to temporomandibular disorders (TMD), gender differences, and perceived treatment need in children and adolescents at a public dental clinic in Linköping, Sweden. ⋯ Overall, TMD-related pain was more common in girls than in boys. A majority of children and adolescents who experienced pain once a week or more perceived a need for treatment. Seven percent of the examined subjects were diagnosed with TMD pain.

Pain in some bruxers has been suggested to represent a state of postexercise muscle soreness. This study examined the effect of voluntary, controlled grinding movements on the development of pain and soreness in the masticatory system. ⋯ These findings suggest that significant but low levels of postexercise muscle soreness can be elicited by standardized grinding movements in the masticatory system of healthy subjects.

A case of episodic, spontaneous odontalgia, aggravated by ingestion of cold food, with no apparent dental pathology is presented. Attempts at alleviating the pain by means of root canal treatment had failed in previous, similar episodes, and pain and pulpal hyperalgesia had shifted to other locations. ⋯ A prophylactic attempt with nifedipine, a calcium channel blocker, failed to alleviate the pain. This diagnostic entity and possible therapeutic approaches are discussed.

Comparative Study
TMD in patients with primary Sjögren syndrome: a comparison with temporomandibular clinic cases and controls.
The aim of this study was to investigate the prevalence of temporomandibular disorders (TMD) in patients with primary Sjögren syndrome (1 degree SS), analyze the impact of the disease on mandibular function, and assess psychosocial distress. ⋯ Both 1 degree SS and chronic TMD may be associated with appreciable physical discomfort and psychosocial dysfunction. However, the underlying mechanisms of the oral dysfunction of 1 degree SS and TMD are quite different and essentially unrelated.
