Impact of PDT and Topical Corticosteroids on Taste Perception in Patients With OLP
Sponsor: Medical University of Bialystok
Summary
Oral lichen planus (OLP) is a chronic inflammatory disease that affects the lining of the mouth and may cause pain, burning sensations, and discomfort. Some patients also report changes in their ability to taste different flavors. The aim of this study is to compare two commonly used treatments for OLP: photodynamic therapy (PDT) and topical corticosteroids. PDT is a light-based treatment that uses a special gel applied to the affected areas, followed by illumination with a medical light device. Topical corticosteroids are anti-inflammatory medications applied directly to the lesions. Participants in this study are randomly assigned to receive one of these two treatments. Before starting therapy and immediately after its completion, patients undergo a simple taste test using special strips that assess the ability to recognize sweet, sour, salty, and bitter tastes. In addition, the size of oral lesions and the intensity of symptoms such as pain or burning are evaluated. The results of this study may help to better understand how different treatments for oral lichen planus affect taste perception and overall patient well-being, and may support the selection of the most appropriate therapy in clinical practice.

Interventions
5-Amino Levulinic Acid
A 5% 5-aminolevulinic acid (ALA) mucoadhesive formulation is applied topically to oral lichen planus lesions. The preparation is administered twice (40 and 20 minutes prior to light irradiation) under occlusive conditions to enhance tissue penetration.
Clobetasol Propionate 0.05% Cream
Clobetasol propionate 0.05% (Clobederm) is applied topically to oral lichen planus lesions twice daily for a period of 5 weeks, according to standard clinical practice.
