Correlation between stress, stress-coping and current sleep bruxism [PDF]
Head & Face Medicine, 2010 Background Stress is discussed as a potential factor in the development of sleep bruxism (SB). The aim of this study was to investigate whether specific stress-factors correlate with SB-activity. Methods Sixty-nine subjects, of which 48 were SB-patients,

Current stress and poor oral health. [PDF]
BMC Oral Health, 2016 Psychological stress appears to contribute to poor oral health systemically in combination with other chronic diseases. Few studies directly examine this relationship.Data from a cross-sectional study of 2,412 participants between the ages of 25-64 years old living in the City of Toronto between 2009 and 2012 were used to examine the relationship ...
