title: Comparison of the effect of combination of triamcinolone acetonide and vitamin a mouthwash with triamcinolone mouthwash alone on oral lichen planus.
abstract: OBJECTIVE
  Lichen planus is a relatively common mucocutaneous disease, with an unknown etiology. There is no complete cure for oral lichen planus (OLP), but some drugs, including corticosteroids, retinoids, cyclosporine and antibiotics are commonly used for treatment of OLP. The aim of the present study was to compare the effect of combi-nation of triamcinolone and vitamin A mouthwash with triamcinolone mouthwash alone on OLP.
  
  
  METHODS
  Twenty OLP patients were randomly divided into two groups of 10. The experimental group was treated with combination of triamcinolone and vitamin A mouthwash and the control group was treated with triamcinolone-containing mouthwash alone. The patients were examined once every two weeks and the lesion size, pain and burning sensation were recorded based on visual analogue scale during a two-month period. Data were analyzed by Mann-Whitney U test using SPSS software.
  
  
  RESULTS
  The use of combination of triamcinolone-vitamin A mouthwash was effective in decreasing the pain and burning sensation of OLP (P = 0.012). Decrease in pain and burning sensation were similar in both groups (P = 0.73). The use of combination of triamcinolone-vitamin A mouthwash led to a decrease in the size of keratotic, atrophic and erosive OLP lesions (P = 0). Decrease in the size of the lesions was significantly greater in the study group compared to the control group (P = 0.029).
  
  
  CONCLUSIONS
  The use of combination of triamcinolone-vitamin A mouthwash is effective in decreasing the size of keratotic, atrophic or erosive lesions.
