status of neutrophils, lymphocytes and platelets in patients with recurrent aphthous stomatitis: a retrospective study

introduction: the aim of this study was to evaluate the neutrophil-to-lymphocyte ratio (nlr), platelet-to-lymphocyte ratio (plr), and mean platelet volume (mpv) in patients with recurrent aphthous stomatitis (ras).   materials and methods: eighty patients who were diagnosed with ras between january 2014 and january 2016 were included in this study. eighty age- and gender-matched healthy subjects were also enrolled as a control group. neutrophil, lymphocyte, and platelet counts were compared between groups, in addition to nlr, plr, and mpv values.   results: there was no significant difference in terms of lymphocyte count, platelet count, plr, or mpv values between the two groups (p>0.05). however, white blood count, neutrophil count, and nlr were significantly higher in patients with ras compared with the control group (p
