A randomized controlled trial to compare steroid with cyclosporine for the topical treatment of oral lichen planus.

To compare the effectiveness of cyclosporine solution versus triamcinolone acetonide in orabase in the treatment of oral lichen planus (OLP) in reducing signs and symptoms. One hundred thirty-nine biopsy-proven OLP patients were randomly assigned to cyclosporine (68) or steroid (71) applied onto the target lesion and affected areas. Assessments were at weeks 0, 2, 4, 8 by clinical scoring and grid measurement of the target lesion (reticulation, erythema, ulceration). Patients ranked severity of pain and burning sensation using visual analog scales. Although clinical response, pain, burning sensation, area of reticulation, erythema, and ulceration at week 4 were all worse in patients receiving cyclosporine than in those receiving steroid, the differences were not statistically significant. Large patient-to-patient variability was evident over the observation period, with little evidence of marked changes in levels over time in both treatment groups. Topical cyclosporine appears no more effective than steroid in the treatment of oral lichen planus.
