Several psychological diseases, mainly stress, anxiety and depression can be associated to temporomandibular disorder (TMD), acting as important collaborators for the settlement and maintenance of this dysfunction. Emotional states and/ or traits associated to stressor factors can lead to oral dysfunctional habits and, consequently, hyperactivity of masticatory musculature, constituting triggering factors of orofacial pain. The aim of this study was to evaluate the presence of anxiety state or trait in asymptomatic individuals and with temporomandibular disorder. Thirty-five volunteers took part in the study, 20 with TMD and 15 asymptomatic ones. The participants were evaluated for the presence and degree of TMD (Anamnestic Index of Fonseca and Anamnestic and Clinical Index of Dysfunction and Occlusal State). Then, the evaluation of anxiety state and trait was carried out by the State-Trait Anxiety Inventory (STAI). It was observed a significant higher incidence of anxiety state (43.3 versus 35.7) and trait (48.1 versus 36.73) in subjects with TMD when comparing them to the asymptomatic individuals. The results suggest that the state and trait of anxiety can contribute for the development and perpetuation of the temporomandibular disorders.
