Plain English Summary

Background and study aims
Oral lichen planus is an inflammatory condition that affects the mucous membranes inside the mouth. There is no specific curative drug or treatment for oral lichen planus and in most cases management relies on corticosteroids for the relief of symptoms. There is research ongoing to find alternative topical therapeutics to corticosteroids. This study aims to compare the effectiveness of topical Amlexanox 5% oral paste and triamcinolone acetonide 0.1% paste in the treatment of oral lichen planus.

Who can participate?
Patients aged 18 to 70 years with oral lichen planus

What does the study involve?
Participants are randomly allocated to be treated with either topical amlexanox paste or triamcinolone acetonide paste. The treatment continues for 1 month with three times daily drug application.

What are the possible benefits and risks of participating?
Both the corticosteroid drug and amlexanox when used in early or mild stages of oral lichen planus can arrest disease progression to severe forms and avoid the use of systemic corticosteroids and immunomodulators. The selected topical drugs have a high safety profile, favourable patient compliance and no systemic side effects.

Where is the study run from?
D Y Patil University, School of Dentistry (India)

Scientific titleComparative efficacy of topical amlexanox 5% oral paste and triamcinolone acetonide 0.1% oromucosal paste in the treatment of oral lichen planus – a randomized control trial
Study hypothesisAmlexanox oral paste has been compared with triamcinolone acetonide 0.1% oromucosal paste (conisidered as the gold standard therapy) in the treatment of oral lichen planus.
Ethics approval(s)Approved 26/11/2021, Institutional Research & Ethical Board (D Y Patil University School of Dentistry, Navi Mumbai, Maharashtra, India; +91 (0)9029999633; dentistry@dypatul.edu), ref: IREB/2021/OMR/09
ConditionOral lichen planus
Intervention30 patients with oral lichen planus were included in the study. After clinical diagnosis and histopathological confirmation, the selected patients were divided into two groups – group A and group B, through a randomization process (chit method [lottery] followed by dispatch in opaque envelopes [allocation concealment]). Patients in group A received 0.1% triamcinolone acetonide oro-mucosal paste (n = 15) and patients in group B received 5% amlexanox oral paste (n = 15) after allocation concealment, for 1 month and their responses to the treatment were recorded.
