Participants completed a questionnaire containing the four\u2010item patient health questionnaire for anxiety and depression (PHQ\u20104) and some items from the Global Adult Tobacco Smoking (GATS) questionnaire. Moreover, they performed one week of awake bruxism behaviours monitoring via the ecological momentary assessment (EMA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 100 participants (university employees, dentists, undergraduate and post\u2010graduate students) were included in the study (34 males and 66 females, mean age 24.5\u2009years). Of them, 39% were smokers and 61% were non\u2010smokers. The multiple variable linear regression analysis results showed a statistically significant correlation between the frequency of awake bruxism behaviours and the PHQ\u20104 scores. Specifically, for every 1% increase in PHQ\u20104 score, the mean frequency of the AB behaviours increases 5\u2010fold. Awake bruxism behaviours did not show any statistically significant correlation with the number of smoked cigarettes (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&gt;\u20090.05).
