Oral lichen planus (OLP) is a chronic inflammatory disease with unknown etiology. There are many clinical types of OLP. OLP cases are often asymptomatic; however, atrophic or erosive forms may cause sensitivity, burning, and discomfort. The best model of the OLP treatment modality is to evaluate the restorations that may lead to oral mucosa hypersensitivity as the first step. Local corticosteroid injection therapy may be preferred to eliminate the possible systemic side effects of systemic corticosteroid medication in patients with OLP. The aim of this case series is to evaluate treatment alternatives in OLP.
