Abstract:
Psychopathologies play a role in the etiology and maintenance of craniomandibular disorders (CMD). In this study, the craniomandibular index was applied to valuate signs and symptoms of CMD in 60 dentate patients, who were assigned to 2 groups: symptomatic (n=35) and asymptomatic (n=25). An interview on psychopathologies was carried out with the aim to detect the presence of some mood disorders, such as depression, dysthymic and bipolar I disorders. Among these disturbances, depression was the most significant aspect to be reported (p<0.05) since it was present in most symptomatic patients. This important interaction was also significantly correlated (p<0.05) with the Palpation Index. These results suggest that psychopathological aspects could increase muscle tenderness and pain in addition to sleep dysfuntions and other physical complaints. Therefore, psychopathologies should be regarded as an important aspect in patients with orofacial pains.
