To establish the presence of depression the Symptom Checklist 90 -Revised test was applied. Saliva was collected between 9:00 a.m. and 9:25 a.m. and saliva cortisol levels were analyzed by spectrophotometry. RESULTS: The Symptom Checklist 90 -Revised has suggested that 64% of patients with temporomandibular disorder were depressed as compared to 43% of individuals without temporomandibular disorder. Saliva cortisol level was 0.272µg/dL for the temporomandibular disorder group and of 0,395µg/dL for the group without temporomandibular disorder, with no statistical difference. CONCLUSION: Within the limits of the study, it was possible to conclude that there is no association among saliva cortisol levels, depression and the presence of temporomandibular disorders.
