[The evaluation of serum vitamin B12, folic acid and hemoglobin levels in patients with recurrent minor aphthous stomatitis].

Abstract This study aims to evaluate the serum levels of hemoglobin, vitamin B12 and folic acid in patients with recurrent minor aphthous stomatitis. Between June 2010 and January 2012, a total of 112 patients including 57 with recurrent aphthous stomatitis (study group; 30 males 27 females; mean age 36.7±13.9 years; range 13 to 74 years) and 45 with chronic tinnitus patients without recurrent aphthous stomatitis (control group; 18 males 27 females; mean age 39.7±15.1 years; range 20 to 80 years) who were admitted to our clinic were included in this study. The serum hemoglobin, vitamin B12 and folic acid levels of the patients were measured and statistically compared. There was no significant difference in serum levels of hemoglobin and folic acid between the groups. Serum levels of vitamin B12 were significantly lower in the study group, compared to the control group (p
