Background: Stress, particularly during exams, is a well-documented factor affecting oral health. Xerostomia, or dry mouth, can be triggered by stress and leads to a variety of oral health issues. This cross-sectional study investigates the prevalence of stress-induced xerostomia among Libyan students during exam periods and explores the relationship between academic-related stress and xerostomia.

Materials and Methods:A total of 700 students from various universities in Libya participated in the study through convenience sampling. A self-administered questionnaire, including the Perceived Stress Scale (PSS-10) and the Xerostomia Inventory (XI), was used to assess exam-related stress and xerostomia symptoms. Statistical analysis was performed using SPSS, with Pearson’s correlation coefficient and logistic regression models used to examine the relationship between stress and xerostomia.

Results: 48% of students reported xerostomia, with a significant positive correlation (r = 0.58, p < 0.001) between stress levels and xerostomia severity. Health sciences students exhibited the highest stress and xerostomia prevalence. Logistic regression indicated that high stress was the strongest predictor of xerostomia (OR = 3.1, p < 0.001).

Conclusion: The study highlights the significant impact of exam-related stress on xerostomia among Libyan students. Findings underscore the need for stress management interventions in educational settings, particularly in high-stress academic disciplines.
