Abstract

Oral lichen planus (OLP) is a chronic inflammatory, immune mediated mucocutaneous disorder of uncertain etiology. Psychologic stress has been found to be a main contributing factor in onset and progression of lesions. Most erosive OLP patients are refractory to available therapies, even corticosteroids, and report remarkable side effects. As photodynamic therapy (PDT) has proved it to be an effective and safe alternative treatment of abnormal or neoplastic cells we employed PDT for this diagnosis. Due to limited literature on application of this method for treatment of refractory erosive OLP, we present a series of 10 cases of bilateral erosive LP treated by 5 -Aminolevulinic acid mediated PDT. Outcome of our clinical cases showed remarkable improvement in lesions with reduction in Reticulation, Erythema, Ulceration (REU) score (from 5 to 3) and burning sensation as recorded by Visual Analogue Scale (Pretreatment VAS ranged from 5 to 8, posttreatment VAS was 0-1). PDT could be used as a complementary treatment method for symptomatic resistant OLP lesions, although our findings necessitate further research to validate the efficacy of this method for control of resistant oral lichen planus.
