Background: Lichen planus is a T-cell-mediated autoimmune disease, in which CD8+ T-cells releases the cytokines such as tumor necrosis factor-alpha and interleukin-12 disrupting basement membrane integrity. Treatment modalities were directed toward the relief in signs and symptoms and preventing recurrences. Zinc activates caspase-3 and DNA fragmentation, resulting in the apoptosis of keratinocytes. Prevention of matrix metalloproteinases1 (MMP1) activation, inhibits the Tcell accumulation in oral lichen planus (OLP) and by inhibiting MMP9, prevents the cleavage of collagen resulting in maintaining the integrity of the basement membrane. Objectives: The main objective of the study is to compare the efficacy of oral zinc 50 mg and 0.1% triamcinolone Orabase with 0.1% triamcinolone Orabase alone on the healing process of symptomatic OLP. Materials and Methods: A total of forty participants were randomly categorized into two groups: Group A and Group B with 20 patients with OLP and having symptoms of burning sensation. Group A patients had received 0.1% triamcinolone Orabase twice daily application. Group B patients had provided with oral zinc 50 mg and 0.1% triamcinolone Orabase twice daily for 8 weeks. The follow-up period for both the groups was 6 months. Lesional size was measured by Thongprasom scale and burning sensation was assessed by visual analog scale at each visit till the cessation of treatment. Results: There was decrease in the burning sensation and lesional size from the first visit to follow-up period which was statistically significant in both groups (P = 0.000). Conclusion: Oral zinc therapy was adjunctive in reducing the burning sensation and lesional size in the symptomatic OLP.
