About

The primary objective of this study was to compare the therapeutic efficacy of clobetasol propionate 0.05% oral gel versus an anti-inflammatory mouthwash in an oral solution for the management of patients suffering from symptomatic OLP. The secondary objective was to analyze which one of the two treatments induced a greater risk of developing side effects.

Full description

Forty patients were assigned (20 patients per group), through a randomized design, to receive clobetasol (clobetasol gel 0.05%), or an anti-inflammatory mouthwash (mouthwash which contains calcium hydroxide, hyaluronic acid, Umbelliferone and Oligomeric Proanthocyanidins) for 3-months. At baseline (T0) and after 3 months (T1), patients were subjected to clinical and oral assessments and were evaluated for the symptoms (Numerical Pain Scale, NRS score) and signs (Thongprasom's score) of OLP. Data were calculated using T-test for the dependent variable, Wilcoxon test and Mann-Witney u test.

Clobetasol treatment

Active Comparator group

Description:

The clobetasol group was treated with clobetasol propionate 0.05%, while the anti-inflammatory group was treated with mouthwash. The drug used consisted of Clobetasol propionate 0.05%, Ethyl alcohol 96° (50%), Hydroxyethylcellulose (4%); Preserved water (just enough to 100%) that was topically applied \[11\]. This drug was produced as a galenic formulation. Clobetasol propionate twice a day (every 12 hours) to the lesions with a soft bristle brush and were advised not to drink or eat during the hour following application of the medication.

Treatment:

Drug: Healing evaluation

Anti-inflammatory mouthwash

Active Comparator group

Description:

In patients of the anti-inflammatory group, the mouthwash was used pure and without dilution at a dosage of 20 ml 3 times a day, immediately after normal daily oral hygiene was prescribed. It contains calcium hydroxide, hyaluronic acid, Umbelliferone and Oligomeric Proanthocyanidins. Patients were instructed to rinse for at least 5 minutes over the entire oral mucosa, with particular emphasis on the regions where the lesions are located.
