Impact of PDT and Topical Corticosteroids on Taste Perception in Patients With OLP
Summary
NIH ClinicalTrials.gov registered a new comparative effectiveness study (NCT07536737) evaluating photodynamic therapy versus topical corticosteroids for treating oral lichen planus and their effects on taste perception. The randomized controlled trial will enroll patients receiving either 5-Amino Levulinic Acid-based PDT or Clobetasol Propionate 0.05% Cream, assessing taste recognition and lesion outcomes. Study findings may inform clinical treatment selection for OLP patients experiencing taste disturbances.
What changed
NIH registered a new clinical trial on ClinicalTrials.gov (NCT07536737) comparing photodynamic therapy (PDT) using 5-Amino Levulinic Acid with topical Clobetasol Propionate 0.05% Cream for treating oral lichen planus. The study will evaluate taste perception changes and symptom reduction across two treatment arms. Participants undergo taste strip testing and lesion assessments before and after therapy.
Healthcare providers and clinical investigators conducting oral medicine or dermatology research may find this study relevant for understanding comparative OLP treatment outcomes. The study represents standard clinical research registration activity and does not impose compliance obligations on regulated entities beyond standard clinical trial requirements.

Impact of PDT and Topical Corticosteroids on Taste Perception in Patients With OLP
N/A NCT07536737 Kind: NA Apr 17, 2026
Abstract
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.
Conditions: Oral Lichen Planus
Interventions: 5-Amino Levulinic Acid, Clobetasol Propionate 0.05% Cream
