The Therapeutic Effect of Curcumin in Nanogels Compared to 0.1% Fluocinolone Acetonide Oral Paste in the Management of Atrophic-Erosive Oral Lichen Planus

Overview

This randomized, double-blind clinical trial evaluates the therapeutic effects of curcumin in nanogels compared to 0.1% fluocinolone acetonide oral paste in the management of atrophic-erosive oral lichen planus (OLP). The study aims to determine whether curcumin nanogels, a natural treatment with enhanced bioavailability, are as effective and better tolerated than standard corticosteroid therapy.

Detailed description

Oral lichen planus (OLP) is a chronic, immune-mediated inflammatory condition that causes painful mucosal lesions and significantly impairs patients' quality of life. Although topical corticosteroids are the standard treatment, their long-term use is associated with adverse effects. Curcumin, a natural compound with anti-inflammatory and antioxidant properties, has shown promise as an alternative treatment. However, its clinical application is limited by poor bioavailability.

This randomized, double-blind, controlled clinical trial aims to compare the therapeutic effects of curcumin in nanogels and 0.1% fluocinolone acetonide oral paste in patients with atrophic-erosive OLP. Thirty eligible participants will be randomly assigned to either the curcumin nanogel or fluocinolone group, and treatment outcomes will be evaluated using the Oral Lichen Planus Disease Activity Scale (OLP-DAS) and a patient satisfaction questionnaire over a 4-week period.

The study is conducted at the Faculty of Dentistry, Chulalongkorn University, and seeks to evaluate whether curcumin nanogels offer comparable therapeutic efficacy to corticosteroids, with potentially fewer side effects.

Interventions

  • Drug Curcumin in Nanogels
    Participants will apply curcumin nanogels to affected oral areas three times daily for 4 weeks.
  • Drug 0.1% Fluocinolone Acetonide Oral Paste
    Participants will apply 0.1% fluocinolone acetonide oral paste to the affected oral mucosa three times daily for 4 weeks. This corticosteroid paste is the standard treatment for oral lichen planus.

Primary outcome measures

  • Change in OLP-DAS Score [Time frame: Baseline, 2 weeks, and 4 weeks]
Secondary outcome measures (1)
  • Product Satisfaction Questionnaire [Time frame: At 4 weeks after treatment start]

  • Presence of symptoms (NRS pain score > 0 at baseline)
  • Ability to communicate and follow instructions
  • Willingness to apply oral paste treatment and comply with study protocol

Exclusion criteria

  • Pregnancy or lactation
  • Current orthodontic treatment
  • Uncontrolled diabetes mellitus (HbA1c > 7% or FPG > 130 mg/dL)
