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.

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.

Comparative Study
Migraine is the most prevalent primary headache in individuals with temporomandibular disorders.
To assess the prevalence of primary headaches (HA) in adults with temporomandibular disorders (TMD) who were assessed in a specialty orofacial pain clinic, as well as in controls without TMD. ⋯ TMD was associated with increased primary HA prevalence rates. Migraine was the most common primary HA diagnosis in individuals with TMD.

Comparative Study
Painful conditioning stimuli of the craniofacial region evokes diffuse noxious inhibitory controls in men and women.
To compare the modulatory effects of tonic mechanical or thermal craniofacial painful conditioning stimuli on pain sensitivity in craniofacial and spinal test sites in healthy men and women. ⋯ This study has documented that mechanical and thermal painful tonic stimuli applied to the craniofacial region can evoke diffuse noxious inhibitory control (DNIC)-like effects in the craniofacial region as well as spinally innervated areas, but without sex differences.

The purpose of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Validation Project was to assess the diagnostic validity of this examination protocol. The aim of this article is to provide an overview of the project's methodology, descriptive statistics, and data for the study participant sample. This article also details the development of reliable methods to establish the reference standards for assessing criterion validity of the Axis I RDC/TMD diagnoses. ⋯ The Validation Project study population was appropriate for assessing the reliability and validity of the RDC/TMD Axis I and II. The reference standards used to assess the validity of Axis I TMD were based on reliable and clinically credible methods.
