Bruxism and other jaw loading behaviours are associated with somatic symptoms and psychological distress in orofacial pain-free adults: a cross-sectional study

In addition to being classified by sleep and awake states, oral behaviours can be grouped into tooth-contact bruxism, non-tooth-contact bruxism and other jaw loading behaviours. The significant correlations observed among oral behaviours, somatic symptoms and psychological distress suggest that individuals reporting frequent oral behaviours should be further evaluated for underlying psychosocial factors, even in the absence of orofacial pain.
