Abstract :
Background: Recurrent aphthous stomatitis (RAS) is among the most common oral lesions and pain is often the chief complaint
of patients. The main etiology of RAS is unknown but several
predisposing factors have been suggested. This study aims to
assess the correlation of blood types (ABO/Rh) with RAS.
Methods: We conducted this prospective screening study on
50 patients with RAS and 50 controls. Both groups received a
questionnaire and underwent serum screening for detection of
blood type (ABO/Rh). The collected data were analyzed by the
independent t-, Fisher’s exact, and chi square tests. P<0.05 was
considered statistically significant.
Results: There was no significant difference observed between
cases and controls in terms of age (P=0.065), sex (P=1.000), blood
type (ABO; P=0.531), and Rh (P=1.000).
Conclusion: Based on the results, blood type (ABO/Rh) is not a
predisposing factor for RAS. However, future studies with larger sample sizes are recommended.
