Associations between self-reported bruxism, sleep quality, and psychological status among dental students in Turkey

Abstract

ABSTRACT Objectives To assess sleep quality among dental students and to identify psychological factors associated with self-reported sleep bruxism (SB). Methods A total of 212 dentistry students from the Usak University Faculty of Dentistry participated in this study. A self-report questionnaire was administered to identify possible SB. The Depression, Anxiety, and Stress Scale (DASS-21) questionnaire was administered to evaluate psychological factors, and the Pittsburgh Sleep Questionnaire Index (PSQI) was used to evaluate sleep quality. Results Possible SB was more frequently observed in females than in males. The mean DASS-21 score in those with possible SB was significantly higher than in those without SB (p< 0.001). The mean PSQI (total) score was also significantly higher in those with possible SB than in those without SB (5.0 ± 2.4) (p= 0.007). Conclusion The findings revealed that psychological factors and sleep quality significantly affected the prevalence of self-reported SB among dental students.
