There is insufficient evidence to make firm recommendations for the use of CBT over other intervention for the treatment of TMD .
Cognitive-behavioural therapy ( CBT ) and its effects on  temporom and ibular disorders ( TMD ) have been examined in several studies .

Long-Term Efficacy of Biobehavioral Treatment of Temporomandibular Disorders
This study evaluated the relative long-term efficacy of biofeedback , cognitive – behavioral skills training ( CBST ) , combined biofeedback and CBST ( Combined ) , and no-treatment comparison groups in 108 patients suffering from chronic temporom and ibular disorder ( TMD ) . After an initial evaluation , patients were assigned to one of the four treatment conditions . The three biobehavioral treatment interventions consisted of 12 st and ardized sessions . Patients were reevaluated 1 year after completing treatment . Results demonstrated that patients who received the biobehavioral treatments reported significant improvement in subjective pain , pain-related disability , and m and ibular functioning 1 year after receiving treatment . The no-treatment comparison group did not demonstrate such improvements . The combined biofeedback and CBST treatment produced the most comprehensive improvements across all outcome measures . These results again demonstrate the heuristic value of adopting a biopsychosocial perspective to the assessment and treatment of chronic medical/dental disorders such as TMD
