Background and Aims: Considering the regulatory role of vitamin D3 in the immune system, this vitamin may be able to prevent autoimmune diseases by modulating the immune system, so this study was conducted with the aim of comparison of the serum level of vitamin D3 in patients with oral lichen planus and healthy persons.
Materials and Methods: In this case-control study, the serum vitamin D3 level of 80 people, including 40 patients referred to Guilan dental school who were suffering from oral lichen planus and 40 healthy individuals referred to the laboratory for routine check-up, after matching for age and gender, was investigated. Data based on the type of variable were analyzed using independent t-tests, Mann-Whitney, Chi-square test, and Fisher's exact test using SPSS26 software at a significance level of 0.05.
Results: In this study, 80 person participated, including 29 women (72.5%) and 11 men (27.5%) in each of two groups of patients with an average age of 52.17 ± 12.12 years and healthy people with an average age of 52.10 ± 12.23 years. The average serum level of vitamin D3 in the control group was significantly higher than the case group (P=0.006). There was no statistically significant relationship between the vitamin D3 serum level and different types of oral lichen planus, gender, duration of disease, and age.
Conclusion: Considering the significant lower mean serum level of vitamin D3 in people with oral lichen planus; vitamin D3 may be effective as a supplement in the healing process of patients' lesions.
