To evaluate the predictive potential of preoperative psychological and psychophysiological variables in estimating severity of postoperative pain following mandibular third molar surgery (MTMS). ⋯ Implementation of clinically relevant preoperative screening methods may offer more efficacious postoperative pain therapies to pain-susceptible individuals undergoing mandibular third molar surgery.

To investigate key factors associated with treatment-seeking for orofacial pain symptoms in community-dwelling adult Chinese people in Hong Kong. ⋯ Professional treatment-seeking for orofacial pain was low in this ethnic group. The strongest predictor of treatment-seeking for orofacial pain was an increase in the number of days when pain was experienced during the past month. Key factors associated with treatment-seeking should be considered when formulating community health outreach programs. A further validation study with a larger sample size is recommended to confirm the present findings.

To evaluate the psychometric properties of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) biobehavioral (Axis II) screening instruments. ⋯ The Axis-II Depression and Graded Chronic Pain instruments have clinically relevant and acceptable psychometric properties for reliability and validity and utility as instruments for identifying TMD patients with high levels of distress, pain, and disability that can interfere with treatment response and course of Axis I disorders.

The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Validation Project has provided the first comprehensive assessment of reliability and validity of the original Axis I and II. In addition, Axis I of the RDC/TMD was revised with estimates of reliability and validity. These findings are reported in the five preceding articles in this series. ⋯ The original standards for diagnostic sensitivity ( < or = 0.70) and specificity (< or = 0.95) should be reconsidered to reflect changes in the field since the RDC/TMD was published in 1992. Pertaining to Axis II, current recommendations for all chronic pain conditions include standardized instruments and expansion of the domains assessed. In addition, there is need for improved clinical efficiency of Axis II instruments and for exploring methods to better integrate Axis I and II in clinical settings.

To determine if myofascial temporomandibular disorder (TMD) pain patients have elevated interstitial concentrations of glutamate in the masseter muscle. ⋯ The present study demonstrates a marked increase in interstitial glutamate concentration in the masseter muscle of myofascial TMD pain patients. These novel findings suggest that peripheral glutamate could be involved in the pathophysiology of myofascial TMD pain.
