Comparative Study Clinical Trial
Effect of contingent electrical stimulation on masticatory muscle activity and pain in patients with a myofascial temporomandibular disorder and sleep bruxism.
To determine whether an intervention reduces oromotor activity and masticatory muscle pain in myofascial temporomandibular disorder (M/TMD) patients with high levels of masticatory muscle activity associated with sleep bruxism. ⋯ Spontaneous pain severity and nighttime oromotor activity vary independently over nights, even in M/TMD patients selected for relatively high levels of both characteristics.

To conduct a systematic review of papers reporting the reliability and diagnostic validity of the joint vibration analysis (JVA) for diagnosis of temporomandibular disorders (TMD). ⋯ This literature is unable to provide evidence to support the reliability and diagnostic validity of the JVA for diagnosis of TMD.

Randomized Controlled Trial Comparative Study
Assessment of proprioceptive allodynia after tooth-clenching exercises.
To (A) evaluate test-retest reliability of vibrotactile sensitivity in the masseter muscle and (B) test if (1) the vibration threshold is decreased after experimental tooth clenching, (2) intense vibrations exacerbate pain after tooth clenching, (3) pain and fatigue are increased after tooth clenching, and (4) pressure pain thresholds are decreased after tooth clenching. ⋯ Experimental tooth clenching appears to evoke moderate levels of pain and fatigue and short-lasting hyperalgesia to mechanical stimulation, but not proprioceptive allodynia. The absence of proprioceptive allodynia does not necessarily exclude delayed onset muscle soreness (DOMS) but warrants further studies on the clinical manifestations of DOMS in jaw muscles.

Comparative Study
Sex-specific differences in patients with temporomandibular disorders.
To explore potential differences in characteristics of patients that might account for sex-specific differences in temporomandibular disorders (TMD). ⋯ Female TMD patients showed greater pain and muscle tenderness on palpation as compared to male TMD patients. They also showed a different age distribution of prevalence of TMD. These results were independent of subjective symptoms, clinical findings, and external factors.

Comparative Study
Why seek treatment for temporomandibular disorder pain complaints? A study based on semi-structured interviews.
To identify potential predictors of self-reported sleep bruxism (SB) within children's family and school environments. ⋯ Aspects upon which care seekers differed from non-care seekers were mainly person-related characteristics. Next to these characteristics, it appeared that inadequate referrals may play a role in care seeking. The use of semi-structured interviews may further improve insights into processes that determine care seeking among people with TMD pain complaints.
