Objectives The prevalence of recurrent aphthous stomatitis (RAS) among the general population worldwide is 20%. This study aims to discover any correlations between RAS predisposing factors and the gender and year of study of undergraduate dental students at the Faculty of Dental Medicine at Airlangga University.

Methods A cross-sectional analytical study using simple random sampling was performed. The respondents answered seven questions on a self-reported online questionnaire set up using Google Forms. Chi-square analyses were conducted to determine any correlation between RAS predisposing factors and the gender and year of study of the students.

Results The highest predisposing factors for RAS in undergraduate dental students were local trauma (77.7%) followed by stress (71.3%) and nutritional deficiencies (41.5%). Stress correlated strongly with the year of study (p = 0.015). There was no correlation between gender and RAS predisposing factors (p > 0.05).

Conclusion There was a correlation between stress, one of the predisposing factors for RAS, and the year of study, but there was no correlation between gender and RAS predisposing factors including local trauma, stress, nutritional deficiency, genetics, allergies, and systemic diseases.
