Relationship between anxiety, quality of life, and sociodemographic characteristics and temporomandibular disorder.

Objectives: The aim of this study was to evaluate the relationship between anxiety, quality of life (QL), and sociodemographic aspects and temporomandibular disorders (TMDs) and to assess the predisposition to TMDs in patients with low QL and anxiety.

Study Design: In total, 120 patients (60 TMD/60 non-TMD) were screened to assess QL (World Health Organization Quality of Life Brief Version [WHOQOL]); anxiety (Beck Anxiety Inventory [BAI]; the State-Trait Anxiety Inventory[STAI-S and -T]; the Hospital Anxiety and Depression Scale [HADS]); and TMD (Research Diagnostic Criteria for Temporomandibular Disorders-RDC/TMD). Pearson's χ test, the Student t test, odds ratio (OR) analysis, and nonconditional logistic regression analysis were performed.
