Introduction Ulcer is often described as a well-circumscribed lesion with an epithelial defect covered in fbrin clot which gives a yellow-white appearance [1, 11]. Recurrent aphthous stomatitis is one of the common lesions in the oral mucosa[59, 30]. Its prevalence varies between 5-66% among different populations with most of the cases of recurrent aphthous stomatitis (RAS) reported in females as compared to males [53, 45, 16, 52]. Recurrent aphthous stoma- titis (RAS) is often described as a recurrent ulcer which tends to reappear following its healing after a period of time [1, 28]. Several studies have reported on the possible factors that may trigger the episodes of recurrent aphthous stomatitis (RAS) which can be in the form of local, hematological, genetic, im- munologic, nutritional, psychological and medication with stress being considered as the major causative agent of recurrent aph- thous stomatitis (RAS). A complex interaction between genetic, Abstract Recurrent aphthous stomatitis (RAS) is one of the common lesions in the oral mucosa. Its prevalence varies among different populations with most of the cases RAS reported in females as compared to males. It is often described as a recurrent ulcer which tends to reappear following its healing after a period of time. Dietary habits are often associated with the onset and trigger episodes of recurrent aphthous stomatitis (RAS). The aim of this study is to evaluate the food intake of patients with recurrent aphthous stomatitis (RAS) and its effects on the development of the lesion. It is a retrospective study conducted by reviewing 86,000 patient case records of the Saveetha Dental College and Hospital, Chennai, India. A total of 152 consecutive case records of patients for a period of June 2019 to March 2020 with signed informed consent and with complete records were retrieved and analysed. Patient’s age, gender, diet and presence of recurrent aphthous stomatitis (RAS) were collected from the patient’s case records. The obtained data was analyzed using the SPSS version 23.0. Descriptive analysis was done for the assessment of age, gender and types of diet involved. Chi square test was used to evaluate the association of recur- rent aphthous stomatitis (RAS) with age, gender and types of diet. Recurrent aphthous stomatitis (RAS) was observed in 76 individuals of this study. Among the individuals with recurrent aphthous stomatitis (RAS), the majority of them were present with mixed diet (49.34%) while only a small portion of them consume vegetarian diet (0.66%). Most of the recurrent aph- thous stomatitis (RAS) cases involved individuals within the 21-30 years age group (21.05%) and those within the 1-10 and 71-80 years age group were the least affected (1.32%). Higher prevalence of recurrent aphthous stomatitis (RAS) is seen in males (33.55%) as compared to females (16.45%). There is a statistically signifcant association between recurrent aphthous stomatitis (RAS) and age but no association with gender and diet. Our study concluded that recurrent aphthous stomatitis (RAS) exhibits higher prevalence in males as compared to females. Age group of 21-30 years exhibited the highest incidence of recurrent aphthous stomatitis (RAS). Statistically signifcant association is present between recurrent aphthous stomatitis (RAS) and age but not for gender and diet. Keywords: Aphthous Ulcer; Allergy; Dietary Habits; Food; Recurrent.
