Comparative Study
Association between rhythmic masticatory muscle activity during sleep and masticatory myofascial pain: a polysomnographic study.
To test for an association between rhythmic masticatory muscle activity during sleep, as assessed according to polysomnographic criteria for sleep bruxism (RMMA-SB), and myofascial pain (MFP), as well as the chance of occurrence of MFP in patients with RMMA-SB. ⋯ (1) RMMA-SB is significantly associated with MFP; (2) although RMMA-SB represents a risk factor for MFP, this risk is low; and (3) DC probably constitutes a stronger risk factor for MFP than RMMA-SB.

To compare prevalences of self-reported temporomandibular joint and muscle disorders (TMJMD)-type pain in the 2002 U.S. National Health Interview Survey (NHIS) by age and gender for non-Hispanic whites (Caucasians) and non-Hispanic blacks (African Americans). ⋯ This is the first report of findings from a nationally representative US sample for TMJMD-type pain by age and race/ethnicity. TMJMD-type pain differed significantly by race, age, and gender after adjusting for socioeconomic status.

Case Reports
Intraosseous lesion in mandibular condyle mimicking temporomandibular disorders: report of 3 cases.
Pain and dysfunction in the temporomandibular joint (TMJ) region represent a diagnostic challenge. Temporomandibular disorders (TMD) are usually diagnosed by means of a thorough patient history and comprehensive clinical examination. ⋯ Neoplasms and pseudotumors of the TMJ are quite uncommon, but their early recognition is necessary in order prevent the delay of correct treatment. This report describes 3 cases of different intraosseous lesions of the mandibular condyle in which the patient was erroneously first treated for a TMD.

To develop a Malay-language version of the Axis II Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) through a formal translation/back-translation process and to summarize available data about the psychometric properties of the translated scales. ⋯ The cross-cultural adaptation of the RDC/TMD into the Malay language is suitable for use in Malaysia.

To test the hypothesis that temporomandibular disorder (TMD) patients have characteristic diurnal patterns of pain that are associated with diurnal or nocturnal parafunctions. ⋯ Strongly linear or curvilinear patterns of pain were not characteristic of this sample of subjects. More than half the subjects reported slightly increasing pain during the day, but the variability within groups was considerable. Increasing and decreasing patterns of pain were independent of self-reported daytime and nighttime clenching and grinding. Self-reported pain patterns may not be used to reliably infer the times when parafunctional activities occur. The presence of lower pain levels during the weekend probably reflects reduction in psychosocial stressors associated with the work week.
