Topical hyaluronic acid in the management of oral lichen planus: A comparative study.

Abstract

Oral lichen planus (OLP) is a chronic mucocutaneous disorder seen in clinical dental practice. Despite the progress in research and advances in knowledge, the successful management of OLP is still difficult to achieve. The aim of the present study was to compare the therapeutic effects of triamcinolone (TA) preparation (0.1%) with hyaluronic acid (HA) preparation (0.2%) in the management of OLP. In total, 40 patients of any age or sex who had symptomatic OLP were selected and randomly divided into two groups. Group I received topical 0.1% TA, and group II received topical 0.2% HA preparation three times per day for a period of 4weeks. Basement data were recorded for each patient. Patients were evaluated on days 14 and 21, and after completing the course of treatment. The visual analog scale (VAS) was used for evaluating pain and burning sensation, along with an evaluation of the degree of erythema and mean area of the lesion. Data were analyzed by SPSS 17.0 software using Mann-Whitney and t test. P≤0.05 was considered statistically significant. Our results showed considerable improvement in all of the parameters evaluated. Baseline characteristics, including pain score, size, and clinical characteristics of the lesions, were not different between the two treatment groups. Both TA and HA were found to reduce the VAS score, the degree of erythema, and size of the lesions after treatment. The application of HA is suggested, and is an effective substitute for TA in the treatment of OLP.
