ABSTRACT
OBJECTIVE: The aim of this study is to examine the associations between white blood cell (WBC), hemoglobin (Hb), neutrophil, lymphocyte, platelet, mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) levels in patients with recurrent aphthous stomatitis (RAS). MATERIALS AND METHODS: For this study, 137 patients with RAS and 137 healthy controls were recruited. The study participants had no systemic diseases except RAS. Serum WBC, Hb, neutrophil, lymphocyte, platelet, MPV, PLR, NLR, ESR, and CRP levels were recorded in the active period for all patients with RAS and controls. RESULTS: There was no statistically significant difference in the WBC, Hb, neutrophil, lymphocyte, platelet, MPV, NLR PLR, ESR, and CRP levels between patients with RAS and controls. CONCLUSION: No differences were observed for WBC, Hb, neutrophil, lymphocyte, platelet, MPV, NLR, PLR, ESR, and CRP levels between patients with RAS and controls. These parameters therefore cannot be used as markers for inflammation or inflammation severity in patients with RAS.
