RESUMO
Recurrent aphthous stomatitis is the most common oral disease yet despite its high prevalence, the etiological factor [s] of this ulcer is not fully understood. The aim of this study was to determine the serum levels of ferritin, iron, and TIBC in patients with RAS. This case-control study was performed on 40 patients with RAS and 40 healthy people [control group]. They were screened through laboratory tests for the indices mentioned above. The data was analyzed by SPSS, chi-square and t-tests. Of 40 patients, 25.6% were found with ferritin deficiency compared to 7.5% of control group [p<0.05] however, no significant difference for other indices were observed. Low ferritin level in patients with RAS is suggesting a relation between RAS and ferritin deficiency
