title: Systemic and topical corticosteroid treatment of oral lichen planus: a comparative study with long-term follow-up.
abstract: BACKGROUND
  Topical corticosteroids are the mainstay treatment for oral lichen planus (OLP), but some authors suggest that systemic corticosteroid therapy is the only way to control acute presentation of OLP.
  
  
  METHODS
  Forty-nine patients with histologically proven atrophic-erosive OLP were divided into two groups matched for age and sex. The test group (26 patients) was treated systemically with prednisone (50 mg/day), and afterwards with clobetasol ointment in an adhesive medium plus antimicotics, whereas the control group (23 patients) was only treated topically with clobetasol plus antimycotics.
  
  
  RESULTS
  Complete remission of signs was obtained in 68.2% of the test group and 69.6% of the control group, respectively (P = 0.94). Similar results were obtained for symptoms. Follow-up showed no significant differences between the two groups. One-third of the patients of the test group versus none in the control group experienced systemic side-effects (P = 0.003).
  
  
  CONCLUSIONS
  The most suitable corticosteroid therapy in the management of OLP is the topical therapy, which is easier and more cost-effective than the systemic therapy followed by topical therapy.
