Comparing Vitamin D Serum Levels in Patients with Oral Lichen Planus and Healthy Subjects

Statement of the problem: lichen planus disease is a chronic inflammatory lesion without a known etiology. recent studies have indicated the role of vitamin d on immune system and proposed its anti-inflammatory effects. purpose: this study aimed to compare vitamin d serum levels in patients with oral lichen planus and healthy subjects. materials and method: in this case‒control study, 18 patients suffering from oral lichen planus referred to the department of oral medicine, tabriz faculty of den-tistry were chosen as the case group and 18 healthy people were chosen as the con-trol group. a 5-ml blood sample was taken from all subjects and the subjects’ vitamin d serum levels were assessed with a vitamin d total (25-hydroxy vitamin d) kit by employing the electrochemiluminescence technique. the results were analyzed and compared by using spss17 statistic software. p< 0.05 was considered statistically significant. results: the mean vitamin d level in serum of patients with oral lichen planus was 30.7±20.38ng/ml and in healthy subjects was 36.45± 15.33ng/ml, the difference was not statistically significant (p= 0.346). conclusion: the difference between the level of vitamin d in the serum of patients suffering from oral lichen planus and healthy individuals was not significant.
