Impact of Topical Clobetasol on Gingival Crevicular Fluid miRNAs in Subjects Affected by Oral Lichen Planus

Impact of Topical Clobetasol on Gingival Crevicular Fluid miRNAs in Subjects Affected by Oral Lichen Planus: a Randomized Clinical Trial

According to recent research, microRNAs (miRNAs) may function as early disease indicators and contribute to the severity of a number of precancerous and malignant oral disorders. The aim of the present study, through a double-blind randomized controlled trial design, is to analyze in the gingival crevicular fluid (GCF) as a non-invasive approach the impact of topical clobetasol on miRNAs expression in subjects affected by oral lichen planus (OLP).

A double-blind randomized controlled clinical trial is conducted in order to evaluate the impact of topical clobetasol on GCF miRNAs expression in subjects with OLP and determine the statistical significance of the outcome variables.

At least 60 patients with OLP, randomly allocated in two groups: placebo group with a 4% hydroxyethyl cellulose adhesive gel and the clobetasol group with the same gel containing clobetasol propionate 0,05%.

Inclusion Criteria:

• The complete correspondence of the most recent WHO clinical and histopathological criteria (2020) for OLP diagnosis.

Exclusion Criteria:

• 1) Previous therapies for OLP during the last six months preceding the study; 2) State of pregnancy or breastfeeding; 3) Contact or drug oral lichenoid lesions; 4) Allergies to the molecules used in the study; 5) HIV seropositivity.
