Patients were divided into three groups: 1) Major (n\u00a0=\u00a075), 2) Minor (n\u00a0=\u00a0123), and 3) Herpetiform aphthae (n\u00a0=\u00a017). The study groups were compared in terms of demographic features, acute phase proteins, and complete blood cell count parameters. Moreover, correlation analyses were performed for the correlation of ulcer severity score (USS) with C\u2010reactive protein (CRP), SII, erythrocyte sedimentation rate (ESR), ferritin, dNLR, NLR, and PLR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Significantly higher values were observed for USS, neutrophil count, ferritin, SII, NLR, and dNLR (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05 for all) in the major and herpetiform aphthae groups compared to the minor aphthae group.
