High prevalence of stress and suicidal ideation in women with temporomandibular disorder: A population-based cross-sectional survey.

Objective: To investigate the association between temporomandibular disorders (TMD) and psychological factors according to gender in a large representative sample.Methods: Participants provided demographic, socio-economic, and behavioral information and responded to questionnaires assessing mental health status regarding perceived stress, mood disturbance, suicidal ideation, and diagnosis of depression. The association between TMD and its risk factors by gender and the association between psychological factors and TMD were statistically analyzed.Results: In men, perceived stress was highly associated with TMD. However, in women, not only perceived stress but suicidal ideation showed significantly high rates of TMD. The suicidal ideation was significantly associated with TMD in women after controlling confounders.Discussion: Current results provide evidence that TMD is associated with stress in both genders and with suicidal ideation, especially in women. This study has important implications for intense screening and evaluation of suicidal ideation among patients with TMD according to gender.
