title: The relationships among depression, pain, and masticatory functioning in temporomandibular disorder patients.
abstract: OBJECTIVE
  To evaluate the effect of comorbid depression and pain on an early biopsychosocial intervention for acute temporomandibular disorder (TMD) patients.
  
  
  METHODS
  Depressed (either current or lifetime; n=32) or nondepressed (n=31) acute TMD patients received a biopsychosocial intervention, and were evaluated at preintervention and again 12 months postintervention by Characteristic Pain Intensity, the Beck Depression Inventory, and a masticatory function test.
  
  
  RESULTS
  Findings revealed that both depressed and nondepressed patients reported comparable pain decreases at 12 months postintervention. Moreover, there were no significant differences between patient groups in masticatory function.
  
  
  CONCLUSIONS
  With appropriate early biopsychosocial intervention, acute TMD patients, regardless of the presence or absence of vulnerability to depression symptomatology, can be effectively treated.
