Treating Oral Lichen Planus (OLP) is a big challenge for clinicians. Despite numerous
existing remedies, to date no effective cure has been found, which is mainly attributed to
the lack of understanding of the pathogenesis of the disease. The investigator's aim was
comparing the effectiveness of topical steroids and diode laser in treating OLP patients.
Twenty-four patients with OLP were allocated into two groups of twelve patients each. One
group was treated with 970 nm diode laser applied twice weekly and the other group was
treated with topical steroids applied four times per day. Patients were followed up for two
months. Pain was recorded using the visual analog score (VAS) and the clinical signs and
symptoms were recorded using the reticular, atrophic, erosive (RAE) sores. Pain and RAE
records were taken before treatment, after treatment and after 2 months.
