BackgroundOral lichen planus is an autoimmune disorder with several challenges in treatment. Photodynamic therapy has been proposed as a new treatment option for the disease.AimThe present study compared the clinical effects of the photodynamic therapy and dexamethasone mouthwash in the treatment of oral lichen planus lesions.Materials and methodsIn this randomized clinical trial, 30 patients with oral lichen planus were included.15 patients were treated with 5% methylene blue mediated photodynamic therapy using Fotosan device for 30seconds (630nm wavelength and 7.2-14.4J/CM2 dose) for 4 sessions in the days 1,4,7,14. In another group, the treatment was done on 15 patients by 0.5mg tab dexamethasone solution in 5cc water, rinsed 4 times in a day within two weeks. The sign score, symptoms scores (pain), clinical severity and treatment efficacy were measured at the days 15,30,60,90 after beginning of the treatment. The results were subjected to Mann-whitney U test in both groups.ResultsNo significant difference existed between two modalities regarding the treatment efficacy index, sign score, symptom score and clinical severity on the 15, 30, 60 and 90 post-treatment days. Decreases in patient's symptoms were statistically significant in both groups.ConclusionPhotodynamic therapy was as effective as the dexamethasone mouth wash in the treatment of oral lichen planus It could be used as a safe modality in the treatment of oral lichen planus lesions without identified side effects.
