BackgroundTemporomandibular pain and jaw dysfunction can have a negative effect on daily life, but these conditions are not well recognized in the health care systems. The general aim was to examine the cross-sectional prevalence of frequent temporomandibular pain and jaw dysfunction in men and women across the lifespan.MethodsThe analysis was based on data from 137,718 individuals (mean age 35 years, SD 22.7) who answered three questions (3Q/TMD) included in the digital health declaration in the Public Dental Health care in the county of Västerbotten, Sweden; Q1: 'Do you have pain in your temple, face, jaw or jaw joint once a week or more?'; Q2: 'Does it hurt once a week or more when you open your mouth or chew?'; and Q3: 'Does your jaw lock or become stuck once a week or more?'ResultsThe prevalence of frequent temporomandibular pain (Q1) was 5.2% among women and 1.8% among men (p < 0.0001). The prevalence of frequent pain on jaw movement (Q2) was 2.5% among women and 0.9% among men (p < 0.0001). The prevalence of frequent locking of the jaw (Q3) was 2.7% among women and 1.2% among men (p < 0.0001).ConclusionsThe study shows that the cross-sectional prevalence of temporomandibular pain and jaw dysfunction varies during the lifespan. For men and women, respectively, symptoms increase during adolescence, peak in middle age and then gradually diminish. The prevalence of these symptoms is significantly higher among women except from the first and last decades of a 100-year lifespan.© 2015 European Pain Federation - EFIC®
