Adjunctive Oral Systemic Vitamin E Therapy on Salivary Nitric Oxide Level in Patients With Erosive Oral Lichen Planus

Oral lichen planus (OLP) is a chronic inflammatory disease affecting the skin, mucous membranes,s and rarely scalp and nails. It is a T-cell-mediated autoimmune disease. Traditional treatment for OLP is topical steroids commonly used to treat mild to moderately symptomatic lesions. Recent treatment modalities for oral lichen planus include micronutrients such as antioxidants including vitamin E that modify the immune system function. The aim of this study is to evaluate the efficacy of adjunctive oral systemic vitamin E therapy on salivary nitric oxide levels in patients with erosive oral lichen planus.
