Objectives: To assess the efficacy of triamcinolone acetonide mouthrinse for treatment of erosive oral lichen planus (OLP), and to evaluate the risk of fungal over-infection.
Patients and methods: Clinical records of all cases of erosive and erosive-ulcerative OLP treated in our Oral Medicine Service over the period 1993-2003 were reviewed. All patients had been treated with mouthrinses containing triamcinolone acetonide at 0.3% (T1) or 0.5% (T2). Clinical outcome for each patient was classified at 1, 3 and 6 months after start of treatment as total remission (TR), partial remission (PR) or no remission (NR). Fungal over-infection was also recorded.
Results: A total of 35 cases were included in the study. Clinical outcomes considering both treatment groups together (T1 + T2) were as follows: at month 1, 28.6% TR, 62.9% PR, 8.6% NR; at month 3, 57.1% TR, 37.1% PR, 5.7% NR; and at month 6, 80.0% TR, 17.1% PR, 2.9% NR. In four patients (11.4%) fungal over-infection was noted during the study period.
Conclusion: Triamcinolone acetonide mouthrinse is an appropriate treatment for erosive OLP, in view of the high efficacy and low risk of fungal over-infection.
