Oral health practices and determinants among university students – A cross-sectional study

Objectives: A knowledge gap exists concerning how university students—a diverse and transitioning demographic—manage their oral health. This study aims to characterise the oral health practices of university students. Methods: This cross-sectional study aimed to evaluate oral health behaviors and perceptions among students at the University of Porto, through an online survey. Results: The findings indicate that while there are positive changes in some areas, such as a slight reduction in sugary drink consumption and increased awareness of oral health, significant areas of concern remain, particularly regarding the frequency of dental floss use and the consumption of sugary foods. Conclusions: While university students demonstrate some positive oral health behaviors, important gaps remain that must be addressed. By implementing targeted educational and support programs that integrate mental health, dietary habits, and stress management, institutions can enhance their students’ oral health and overall well-being, as underscored by this study's comprehensive approach to oral health promotion strategies.
