To examine the psychometric characteristics of a measure of self-efficacy for managing temporomandibular disorders (TMD) and to determine whether scores on this measure were related to pain, disability, and psychological distress in patients with chronic TMD pain. ⋯ Self-efficacy for managing pain appears to be important in the adjustment of patients with chronic TMD pain. Research is needed to determine whether treatments designed to increase self-efficacy improve TMD patient outcomes.
-
To examine the relationship between different types of self-reported oral parafunctions and pain intensity in patients with temporomandibular disorders (TMD). ⋯ No clinically relevant relationships were found between different types of self-reported oral parafunctions and TMD pain complaints.

Comparative Study
Cyclic effects on experimental pain response in women with temporomandibular disorders.
Since cyclic effects on experimental pain response in women with temporomandibular disorders (TMD) have not been adequately studied, the aim of this study was to assess variations in experimental pain response at 4 phases of the menstrual cycle. ⋯ Phase-related differences in experimental pain response were not strong and were more often found for experimental stimuli with greater clinical relevance (ie, palpation pain) compared with an ischemic pain task.

To outline the steps taken to conduct and to culturally adapt Dutch translations of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) history questionnaire, clinical examination form, and verbal instructions to the patients, and to assess the reliability of the clinical examination. ⋯ The mode described by the authors for preparing clinical sites for RDC/TMD-based research is a feasible one.

To examine whether catastrophizing is associated with clinical examination findings, pain-related activity interference, and health care use among patients with pain related to temporomandibular disorders (TMD). ⋯ TMD patients who catastrophize have higher scores on clinical examination measures reflecting more widely dispersed and severe pain upon palpation of TMD-related facial muscle and joint sites, as well as greater TMD-related activity interference and health care use. Clinicians should consider screening patients with moderate or greater TMD pain and activity interference for catastrophizing. Cognitive-behavioral interventions may help reduce pain, disability, and health care use of patients who catastrophize.
