Correlation between the Oral and Mental Health of University Students in Serbia-A Cross-Sectional Study

This cross-sectional study aimed to assess the correlation between subjective oral health status and mental health in a group of university students in Serbia.

The study included 948 students, aged between 18 and 27, from the Faculty of Medical Sciences, University of Kragujevac, Serbia, and was conducted in 2020. The World Health Organization's Oral Health Questionnaire for Adults was utilized to evaluate the respondents' self-perceived oral health and oral hygiene practices. The existence of depressive symptoms was evaluated using the Beck Depression Inventory-II (BDI-II), and the Zung self-rating anxiety scale (SAS) was used for determining anxiety symptoms.

It is observed that 28.9% of respondents exhibit symptoms of depression and 42.3% showed symptoms of anxiety. Results show that students with severe depression and anxiety symptoms very often reported lower self-perceived oral health and oral health problems. Although the nature of this relationship has not been thoroughly evaluated, several studies have shown a mutually dependent connection between oral health and mental health.

The results suggest that some aspects of oral health are associated with higher risks of developing symptoms of depression or anxiety, and vice versa.
