Abstract

ABSTRACT 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.
