Abstract
Background: The most prevalent ulcerative disorder affecting the oral mucosa is aphthous ulcer. Its etiology is
associated with a number of etiological factors. Twenty-five percent of people get aphthous ulcers. Numerous studies
have now shown its link to stress. A sample of Iraqi dentistry students was the subject of an observational research.
Materilas and Method: By distributing a questionnaire, 790 dental students participated in a cross-sectional study.
A statistical study that was both descriptive and inferential was conducted.
Results: Aphthae ulcers were most frequently observed on the buccal mucosa and demonstrated a strong correlation
with the stress experienced throughout the examination.
Conclusion: The current study highlighted the connection between aphthae ulcers and exam-related stress as a
significant contributing factor to the development of this kind of ulcer in dentistry students.
