摘要

Bruxism is currently conceptualized as a jaw-muscle activity that may be influenced by psychosocial factors and is not considered a disorder per se. This cross-sectional study investigated the associations between self-reported possible sleep bruxism (SSB), dental anxiety, and health-related quality of life among final-year medical and dental students. Data were collected from 162 participants. SSB was assessed at a screening level using self-report items based on contemporary consensus recommendations. Dental anxiety was measured with the Modified Dental Anxiety Scale (MDAS), and quality of life was evaluated using the physical and mental component summary scores (PCS and MCS) of the Short Form-12 (SF-12). Students classified as having SSB showed significantly higher dental anxiety levels and lower PCS and MCS scores compared with non-SSB peers. In multivariate analyses, SSB remained associated with lower PCS and MCS scores after adjustment for sex and MDAS total score. These findings suggest that SSB may coexist with increased psychosocial burden and reduced perceived well-being in healthcare students. Longitudinal studies using standardized multidimensional assessment approaches are needed to clarify the directionality and clinical relevance of these associations.
