Journal of Dental Sciences

Abstract Background/purpose Microcytosis is defined as having mean corpuscular volume (MCV) < 80 fL. This study evaluated whether 78 oral lichen planus (OLP) patients with microcytosis (microcytosis/OLP patients) and 510 OLP patients without microcytosis (non-microcytosis/OLP patients) had higher frequencies of anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity than 588 healthy control subjects. Materials and methods Complete blood count and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 78 microcytosis/OLP patients, 510 non-microcytosis/OLP patients, and 588 healthy control subjects were measured and compared. Results We found that 71.8 %, 46.2 %, 10.3 %, 0.0 %, 18.0 %, and 20.5 % of 78 microcytosis/OLP patients and 18.0 %, 12.4 %, 10.2 %, 1.4 %, 21.6 %, and 24.1 % of 510 non-microcytosis/OLP patients had blood hemoglobin, serum iron, vitamin B12, and folic acid deficiencies, hyperhomocysteinemia, and serum GPCA positivity, respectively. Both 78 microcytosis/OLP patients and 510 non-microcytosis/OLP patients had significantly higher frequencies of blood hemoglobin, serum iron and vitamin B12 deficiencies, hyperhomocysteinemia, and serum GPCA positivity than 588 healthy control subjects (all P -values <0.001). Moreover, 78 microcytosis/OLP patients had significantly higher frequencies of blood hemoglobin and serum iron deficiencies than 510 non-microcytosis/OLP patients. Conclusion We conclude that our 78 microcytosis/OLP patients and 510 non-microcytosis/OLP patients have significantly higher frequencies of anemia, serum iron and vitamin B12 deficiencies, hyperhomocysteinemia, and serum GPCA positivity than 588 healthy control subjects. Moreover, 78 microcytosis/OLP patients also have significantly higher frequencies of blood hemoglobin and serum iron deficiencies than 510 non-microcytosis/OLP patients.
