Meta Analysis
Critical appraisal of methods used in randomized controlled trials of treatments for temporomandibular disorders.
To evaluate the quality of methods used in randomized controlled trials (RCTs) of treatments for management of pain and dysfunction associated with temporomandibular muscle and joint disorders (TMJD) and to discuss the implications for future RCTs. ⋯ Much of the evidence base for TMJD treatments may be susceptible to systematic bias and most past studies should be interpreted with caution. However, a scatter plot of RCT quality versus year of publication shows improvement in RCT quality over time, suggesting that future studies may continue to improve methods that minimize bias.

Randomized Controlled Trial Comparative Study
Glutamate-induced temporomandibular joint pain in healthy individuals is partially mediated by peripheral NMDA receptors.
To determine if glutamate injected into the healthy temporomandibular joint (TMJ) evokes pain through peripheral N-methyl-D-aspartate (NMDA) receptors and if such pain is influenced by sex or sex steroid hormones. ⋯ Glutamate evokes immediate pain in the healthy human TMJ that is partly mediated by peripheral NMDA receptors in the TMJ.

Review Comparative Study
Reviewing the evidence: can cognitive behavioral therapy improve outcomes for patients with chronic orofacial pain?
To review evidence for chronic orofacial pain management using cognitive behavioral therapy (CBT). ⋯ CBT, either alone or in combination with biofeedback, conservative treatment and/or self-care, can improve outcomes for patients with TMD in secondary care. However, further research is needed to assess its effectiveness in primary care and in management of other chronic orofacial pain conditions. Further, the number of sessions needed, mode of delivery, and cost-effectiveness also remain unclear.

Randomized Controlled Trial
Short-term effects of dry needling of active myofascial trigger points in the masseter muscle in patients with temporomandibular disorders.
To investigate the effects of dry needling over active trigger points (TrPs) in the masseter muscle in patients with temporomandibular disorders (TMD). ⋯ The application of dry needling into active TrPs in the masseter muscle induced significant increases in PPT levels and maximal jaw opening when compared to the sham dry needling in patients with myofascial TMD.
