Nutritional status effect on recurrent aphthous stomatitis

Recurrent aphthous stomatitis (RAS) is an ulcerated lesion that occurs repeatedly on the oral mucosa. The highest prevalence of SAR in Indonesia is in the age group 15-24 years, the average age of students in Indonesia. Some students have bad eating behavior due to several factors. It, if it happens continuously, will cause nutritional deficiencies. This condition can play a role in the emergence of Recurrent Aphthous Stomatitis (RAS). The purpose of this research is to ascertain how dietary habits and the incidence of RAS are related. The present cross-sectional research applies an analytical observational methodology. Undergraduate dental students in the UMY Study Program represented the study’s population. Out of a total of 333 students, 226 students met the inclusion criteria. The pattern of eating behavior was measured using a Semi-Food Frequency Questionnaire (FFQ), and the incidence of RAS was measured using a Recurrent Aphthous Stomatitis Diagnosis (RASDX. The relationship between FFQ and RASDX was analyzed through the Contingency Coefficient correlation test. The results of the Contingency Coefficient correlation test showed that there was a significant relationship between iron consumption and the incidence of RAS with p-value = 0.045 (p 0.05). Dietary behavior in iron consumption is associated with the occurrence of RAS, while dietary behavior in consuming vitamin B12 is not associated with RAS.
