Background: Recurrent aphthous stomatitis (RAS) is one of the most common oral ulcerative diseases with unknown etiology. Epidermal growth factor (EGF) has been suggested to play a similar role in RAS. Therefore, this study investigated the salivary EGF level in patients with RAS, the patients without RAS, and smokers. Materials and Methods: A total of 91 samples were recruited in this case-control study: 30 RAS patients, 30 controls, and 31 smokers. Age and gender were matched in the groups. In the case group, the salivary sample was taken during the infection and remission periods. Salivary EGF concentration was measured by Crystal Dibiotic assay (made in China) using ELISA technique. Finally, the data were analyzed by SPSS software (Version 18.0, Inc., Chicago, IL, USA). Results: The results of paired t-test showed no statistically significant difference in salivary EGF between the infection and remission periods (P = 0.987). ANOVA test showed a statistically significant difference in EGF between the study groups (P < 0.001), as the mean salivary EGF was significantly lower in the smokers than the case and control groups during the infection and remission periods. Conclusion: The present study showed a lower level of salivary EGF in the smokers without a history of RAS. There was no statistically significant difference between the infection and remission periods in salivary EGF in the patients with RAS. Furthermore, salivary EGF showed no statistically significant difference between the patients with RAS and the controls.
