TMD symptoms and tooth loss worsened OHRQoL. Lower education degree (OR: 6.31, <jats:italic>P<\/jats:italic> = 0.019), TMD-related pain symptoms (OR: 10.62, <jats:italic>P<\/jats:italic> = 0.005), tooth loss (OR: 3.12, <jats:italic>P<\/jats:italic> = 0.035), sleep disorders (OR: 2.92, <jats:italic>P<\/jats:italic> = 0.049) and relatively close contacts (OR: 3.95, <jats:italic>P<\/jats:italic> = 0.020) were verified as risk factors for increased level of anxiety. With respect to depression, low socio-economic status (OR: 6.22, <jats:italic>P<\/jats:italic> = 0.021), TMD-related pain (OR: 7.35, <jats:italic>P<\/jats:italic> = 0.012), tooth loss (OR: 4.48, <jats:italic>P<\/jats:italic> = 0.009), sleep disorders (OR: 5.13, <jats:italic>P<\/jats:italic> = 0.007) and relatively close contacts (OR: 12.94, <jats:italic>P<\/jats:italic> = 0.001) were identified as independent factors for developing depression. Additionally, drinking (B: \u22122.584, <jats:italic>P<\/jats:italic> = 0.013) and never going to the dental clinic (B: \u22123.675, <jats:italic>P<\/jats:italic> = 0.024) were relevant to better OHRQoL, while TMD without pain (B: 2.797, <jats:italic>P<\/jats:italic> = 0.008), TMD-related pain (B: 12.079, <jats:italic>P<\/jats:italic> &amp;lt; 0.001), tooth loss (B: 2.546, <jats:italic>P<\/jats:italic> = 0.006), sleep disorders (B: 2.598, <jats:italic>P<\/jats:italic> = 0.003) were independent factors for impaired OHRQoL.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Painful TMD symptoms, tooth loss and sleep disorders were the impaired risks of psychological states.
