Abstract
BACKGROUND: Hypovitaminosis, or vitamin deficiency, has been increasingly recognized as a potential contributing factor in the development of recurrent aphthous stomatitis (RAS), a condition characterized by the periodic formation of painful ulcers in the oral mucosa. MATERIALS AND METHODS: This mini review includes a literature search on PubMed, Web of Science, and Scopus databases using keywords "hypovitaminosis AND aphthous ulcers." RESULTS: There is a growing body of evidence supporting the link between various vitamin deficiencies-particularly vitamins B12, C, and folate-and the prevalence of RAS, with implications for both diagnosis and management. CONCLUSION: This review aims to outline the clinical and biochemical findings associated with hypovitaminosis in individuals presenting with RAS, emphasizing the diagnostic importance of recognizing vitamin deficiencies in these patients and exploring possible therapeutic approaches.
