Current international consensus regards it as a motor behaviour rather than a disorder, and one that may act as a risk factor for tooth wear and temporomandibular disorders; psychosocial stress is among its most consistently reported associated factors. Clinical\u2010year dental and medical students face intense academic and clinical pressure that may predispose them to both stress and bruxism, yet no published Ghanaian data on this relationship previously existed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A cross\u2010sectional study was conducted among clinical\u2010year (4th\u20136th year) dental and medical students at the University of Ghana, Korle Bu campus. A stratified sample of 291 students, proportionally allocated by course and clinical year, completed a self\u2010administered online questionnaire comprising a 12\u2010point bruxism knowledge module, a 10\u2010item bruxism symptom screening module and the 30\u2010item Perceived Stress Questionnaire (PSQ). Prevalence estimates are reported with 95% confidence intervals (CIs). Associations were examined using chi\u2010square tests, multivariable linear regression, and Pearson and Spearman correlation coefficients, at\n                      <jats:italic>\u03b1<\/jats:italic>\n                      \u2009=\u20090.05.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Participants had a mean age of 23.6\u2009\u00b1\u20092.3 years; 55.0% were male, and 85.2% were medical students.
