Background: This study aimed to investigate the degree of occupational stress and the clinical mental state of dentists. In addition, we investigated the correlation of occupational stress with depression, anxiety, and sleep among dentists in Korea. Methods: A cross-sectional survey on 231 dentists was conducted using the Doctor Job Stress Scale, Center for Epidemiologic Studies Depression Scale (CES-D), State-Trait Anxiety Index (STAI), and Pittsburgh Sleep Quality Index (PSQI). Correlation of occupational stress with mental health was investigated by adjusted multiple regression analysis. Results: The scores of CES-D, STAI, and PSQI revealed a significant correlation with the Doctor Job Stress Scale (t=3.93, P<0.0001; t=4.05, P<0.0001; t=4.18, P<0.0001, respectively). In particular, patient factors and clinical responsibility/judgment factors were significantly associated with depression (t=2.80, P=0.0056; t=4.93, P<0.0001, respectively), anxiety (t=2.35, P=0.0195; t=5.11, P<0.0001, respectively), and sleep (t=3.78, P=0.0002; t=4.30, P<0.0001, respectively), whereas work factors were not associated with any mental health state. Conclusions: This study confirms that dentists as professions experience more severe mental states. For successful mental health care among dentists, stress management focusing on interpersonal relationship with patients and responsibility as an expert rather than the intensity of work should be considered.
