Upper airway volume assessment using Cone-Beam Computed Tomography (CBCT) and Polysomnography: Patients in the study group will undergo validated questionnaires assessing psycho-emotional well-being and selected aspects related to the functioning of the stomatognathic system, upper airway volume assessment using CBCT tomography and polysomnography.

Study summary

The relationship between obstructive sleep apnea (OSA), sleep bruxism, and temporomandibular disorders is becoming clearer, but data on how upper airway volume affects bruxism due to OSA is limited. 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.
