Current therapeutic modalities for severe oral lichen planus are generally unsatisfactory. Steroid treatment of lichem planus has been reported in the dermatology literature and dental literature, but few reports mention its efficacy for oral lesions. Some cases of severe erosive oral lichen planus revealed good response to this agent. So the author report two cases of erosive oral lichen planus treated with 0.05%. Dexamethasone methyl cellulose mouth wash and two intralesional injections of Triamcinolone acetonide suspension 0.2 mls, one week apart. 1. Subjective improvement was noticed in 4-5 days by two patients. 2. Objective improvement, however, was delayed and became apparent at several weeks 3. Continued improvement was noted in all patients.
