OBJECTIVE: To evaluate the prevalence of temporomandibular disorders (TMD) and their association with sociodemographic and psychosocial factors among 33- to 35-year-old Finnish adults in the Northern Finland Birth Cohort 1986 (NFBC1986). METHODS: The sample included 1788 NFBC1986 subjects that have been clinically examined in 2018-19. TMD symptoms were inquired, and clinical TMD examinations were performed based on the Diagnostic Criteria of TMD (DC/TMD). Sociodemographic factors and depression/anxiety symptoms based on Hopkins Symptoms Checklist-25 (HSCL-25) and Generalized Anxiety Disorder-7 (GAD-7) were inquired using questionnaire. RESULTS: The prevalence of at least one of TMD symptoms was 30.4%. Women had higher prevalence of TMD symptoms and diagnoses compared to men. Female sex, anxiety/depression symptoms and socioeconomic group associated significantly with TMD pain symptoms and pain-related diagnoses. CONCLUSION: The most frequent TMD diagnosis was myalgia and 26.4% had at least one TMD diagnosis. Anxiety/depression symptoms were associated with TMD symptoms and pain-related diagnoses.
