en Comparison of Serum Folic Acid Level in Oral Lichen Planus Patients and Healthy Subjects Oral & maxillofacial surgery Oral & maxillofacial surgery Original article Original article <div style="text-align: justify;">Background and aim: Oral lichen planus (OLP) is a chronic mucocutaneous inflammatory disease. Although the etiology of this disease is unknown, some factors including stress, antioxidant deficiency, and folic acid deficiency have been claimed to have a role in its incidence. The purpose of this study was to assess and compare the serum folic acid level in OLP patients and healthy subjects. Materials and methods: in this case-control study, 52 OLP patients (36 females and 16 males) were selected as the case group, and 48 healthy individuals (36 females and 12 males) were assigned to the control group. The serum folic acid level was measured in the two groups. Data were analyzed using T-test with the level of significance set at 0.05. Results: the mean and standard deviation (SD) of serum folic acid level was equal to 8.74±4.11 ng/ml in the case group and 9.12±3.5 ng/ml in the control group with no statistically significant difference (P=0.12). Conclusion: The results of the present study indicated that the serum folic acid level in OLP patients did not have a significant difference with that in healthy subjects.</div> Oral Lichen Planus, Folic Acid, Antioxidants 12 15 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-25-1&slc_lang=en&sid=1 AR Mirzaie 100319475328460010639 100319475328460010639 No Dentist, member of dental laser research center of Hamedan university M Hashemi Shahzadeh 100319475328460010640 100319475328460010640 No Dentist M Barzegari 100319475328460010641 100319475328460010641 No Assistant Professor of dermatology, Tehran university of Medical Sciences,Tehran, Iran.
