title: Biopsychosocial factors associated with the subcategories of acute temporomandibular joint disorders.
abstract: OBJECTIVE
  To assess the biopsychosocial factors associated with acute temporomandibular disorders (TMD) based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD).
  
  
  METHODS
  Participants were assessed in community-based dental clinics and evaluated by trained clinicians using physical and psychosocial measures. A total of 207 subjects were evaluated. Patients' high-risk versus low-risk status for potentially developing chronic TMD was also determined. Analyses of variance and chi square analyses were applied to these data.
  
  
  RESULTS
  Participants' characteristic pain intensity differed among RDC/TMD Axis I diagnoses. They also significantly varied in their self-reported graded chronic pain, depression, somatization (pain inclusive), somatization (pain excluded), and physical well-being. In addition, participants with differing RDC/TMD Axis I diagnoses varied in self-reported pain during their chewing performance. Finally, there were also significant differences in chewing performance between high-risk versus low-risk (for developing chronic TMD) patients.
  
  
  CONCLUSIONS
  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.
