Recent studies have shown that Cone-Beam Computed Tomography (CBCT) accurately images the upper airway, enabling analysis of its volume and its potential impact on bruxism. CBCT uses low radiation doses, significantly lower than harmful levels, making it a safe method for such assessments. Understanding these relationships can inform clinical practices for managing sleep bruxism, which affects 21% of the global population. The study aims to explore how upper airway volume influences the intensity of sleep bruxism related to OSA.",[75,76,77],"Sleep Apnea Syndrome, Obstructive","Bruxism, Sleep-Related","Upper Respiratory Tract Illness",[79,76],"Sleep Apnea","NOT_YET_RECRUITING","2026-03-30",{"date":83,"type":84},"2026-04-06","ACTUAL",{"date":86,"type":71},"2026-09",{"date":88,"type":71},"2026-11",{"name":5,"class":6},1]
