Study on Treatment for Patients With Symptomatic Oral Lichen Planus

Thirty nine patients were assigned, through a randomized design, to receive tacrolimus ointment 0.1% or a mouthwash composed of calcium hydroxide 10%, hyaluronic acid 0,3%, umbelliferone and oligomeric proanthocyanidins, or an anti-inflammatory mouthwash (mouthwash which contains calcium hydroxide, hyaluronic acid, Umbelliferone and Oligomeric Proanthocyanidins) for 3-months. At baseline (T0) and after 3 months (T1), patients were subjected to clinical and oral assessments and were evaluated for the symptoms (Numerical Pain Scale, NRS score) and signs (Thongprasom's score) of OLP. Data were calculated using T-test for the dependent variable, Wilcoxon test and Mann-Witney u test.
