[Matched case control study for investigating of the association between psychosocial factors and TMJDS]

A 1:1 matched case control study was carried out in 81 cases with temporomandibular joint dysfunction syndrome (TMJDS) who came to a TMJ clinic of a tertiary dental centre for help and 81 controls without TMJDS to investigate the association between psychosocial factors and TMJDS. The results showed that anxiety and depression might be one of the risk factors of TMJDS. Trait anxiety and Eysenck's neuroticism might be the inherent personality factor of anxiety, and the later might be the basis of depression. Life events and social support might be the external factors of TMJDS.
