Sponsored by TC Erciyes University · Observational
This cross-sectional observational study evaluates sleep quality and associated factors among 147 dentists working in university, public, and private healthcare settings in Türkiye. Data were collected using a Personal Information Form and the Pittsburgh Sleep Quality Index (PSQI). The study aims to determine the prevalence of poor sleep quality and examine its associations with practice setting, sociodemographic characteristics, occupational factors, and lifestyle behaviors using multivariable logistic regression.
Sleep quality is relevant to cognitive performance, fine motor control, and clinical decision-making in dentistry. This cross-sectional observational study was conducted between May 2024 and January 2025 among 147 dentists working in university, public, and private healthcare settings in Türkiye.
Data were collected using a structured 15-item Personal Information Form and the validated Turkish version of the Pittsburgh Sleep Quality Index (PSQI). The Personal Information Form collected information on sociodemographic characteristics, working hours, graduation year, specialist status, smoking, and daily caffeine intake calculated in milligrams.
Sleep quality was assessed using the PSQI global score. Scores greater than 5 were classified as poor sleep quality, and scores of 5 or lower were classified as good sleep quality. Binary logistic regression analyses using the enter and backward Wald methods were used to examine associations between poor sleep quality and practice setting, sociodemographic characteristics, occupational factors, and lifestyle behaviors while adjusting for other variables included in the models.
