Evaluation of Topical Rebamipide Versus Topical Betamethasone for Management of Oral Ulcers in Behcet's Disease

This is a Randomized clinical trial (RCT) parallel groups, two arm, equivalence framework with 1:1 allocation ratio which is based on the hypothesis that Topical rebamipide has comparable effect to topical betamethasone on oral ulcer severity in patients with Behcet's disease The participants in this study will be recruited from the Rheumtology Clinic, Kasr el ainy hospital by HL as well as Oral Medicine Clinic and the dental Diagnostic center, Faculty of Dentistry, by MB. The eligible participants will be enrolled in the study in a consecutive order till the sample size is achieved. Simple randomization will be generated using computerized random number generator (random.org) with allocation ratio (1:1). Allocation concealment will be done using sequentially numbered opaque sealed opaque containers of the same shape, size and colour until interventions are assigned. The entire procedure will be explained to the patients and a written consent will be obtained by the operator. Participants and care givers will be blinded as both topical rebamipide and topical betamethasone mouthwashes will be of same consistency and will be provided in sealed opaque containers of the same shape, size and colour. The enrolled patients will be divided randomly into two groups. One group will receive topical rebamipide mouthwash four times daily for one week or till healing and the other group will receive topical Corticosteroid (topical betamethasone) four times daily for one week or till healing. The patients will be recalled during the first week (days 1, 3, and 7), then every week for 3 weeks, afterward every month for 2 months. The patients will be asked to prohibit use of any topical medication during the trial. Outcome measures will be recorded in each visit. Data will be analyzed using IBM SPSS advanced statistics (Statistical Package for Social Sciences), version 24 (SPSS Inc., Chicago, IL)
