Evaluating the Causative Cycle of Stress and Oral Aphthous Incidence in an Iranian Population

Oral recurrent aphthous stomatitis (RAS) is the most common ulcer that clinician should be managed. It entails approximately 10-20% of people regarding the geographic and genetic pattern of society. Some literatures reported RAS episodes in Stressful events. Patients experience repeating cycle of aphthous, pain, and recurrence. Stress and inheritance as a crucial factor on RAS incidence was studied. This study aimed to assess the effect of stress on incidence of oral aphthous ulcer between girl students. In this cross-sectional descriptive analytic study, 248 female students from Yazd high schools were evaluated, before and after a period of stress. Informed consent was taken before oral examination. About 248 students were partaken, only 62 persons had RAS which 32 had positive parental involvement. Correlation between familial history and experience of RAS was significant. (P < 0.001). According to the data, stress had considerable effect on RAS incidence with 67.7%. Aphthous incidence was significantly different (P < 0.001).
