To test whether patients with temporomandibular disorder (TMD) pain differ from subjects from the general population with regard to their stress-related coping styles. ⋯ Differences in the applied stress-related coping styles of TMD patients and subjects without TMD may have implications for clinical decision making and choosing among treatment alternatives.

To test the hypothesis that estimates of time spent in tooth contact are significantly greater than estimates of time spent clenching, and to test the hypothesis that tooth contact is greater in pain patients, particularly those reporting facial or head pain, than those with pain elsewhere in the body. ⋯ Results from the logistic regressions provide convergent validity on the importance of oral parafunctions, specifically tooth contact and clenching, to facial/head pain. For assessment of oral parafunctional behaviors, inquiries that utilize clear behavioral referents (tooth contact versus clenching) are likely to result in more accurate estimates than behaviors with unclear definitions.

Peripheral painful traumatic trigeminal neuropathy: clinical features in 91 cases and proposal of novel diagnostic criteria.
To field-test carefully designed criteria for pain following trigeminal nerve trauma. ⋯ Overall, the proposed PPTTN criteria have proven to be clinically useful. In view of these results, modified PPTTN diagnostic criteria are proposed for use in future research.

Comparative Study
Biopsychosocial factors associated with the subcategories of acute temporomandibular joint disorders.
To assess the biopsychosocial factors associated with acute temporomandibular disorders (TMD) based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). ⋯ Participants with multiple diagnoses reported higher pain, as well as other symptoms, relative to participants without a TMD diagnosis. For chewing performance, participants with mutual diagnoses reported more pain compared to other participants. Finally, the risk-status of patients significantly affected chewing performance.

To determine whether mucosal pain, evoked through a novel topical capsaicin model, has an effect on jaw movement and whether psychologic factors have an association with any pain-induced movement effects. ⋯ Capsaicin-induced mucosal pain resulted in a significant increase in chewing rate but had no effect on amplitude or velocity in opening/closing jaw movements and chewing. Anxiety and depression scores correlated negatively with velocity in free opening jaw movement and chewing rate, respectively.
