Mucoadhesive Film With/without Acmella Oleracea & Triamcinolone Acetonide for Aphthous Ulcers

Comparison of the Efficacy of Mucoadhesive Film with and Without Acmella Oleracea Extract and 0.1% Triamcinolone Acetonide for Treatment of Aphthous Ulcers: a Randomized Control Trial

The purpose of this study is to evaluate the effectiveness of mucoadhesive film with or without Acmella oleracea extract compared to standard treatment by using 0.1% triamcinolone acetonide in pain relief, promoting wound healing, healing time and satisfaction in 3 aspects included taste, product used and quality of life after using the product.

Participants who consent and meet the inclusion criteria will be allocated into 3 groups using block randomization: group 1: mucoadhesive film with Acmella oleracea extract, group 2: 0.1% triamcinolone acetonide, and group 3: mucoadhesive film without Acmella oleracea extract.
