This study compared the efficacy of topical tacrolimus ointment with triamcinolone acetonide ointment in patientswith oral lichen planus. Twenty patients (group I) were treatedwith topical tacrolimus 0.1% ointment 4 times daily, and 20 (group II) were treated with triamcinolone acetonide 0.1% ointment 4 times daily. The clinical effect was graded after 6 weeks. In group I, 6 patients healed, 12 showed improvement and 2 showed no improvement. In group II, 2 patients healed, 7 improved and 11 showed no improvement. The most commonly reported side-effect in both groups was temporary burning or stinging at the site of application. Unfortunately, oral lesions recurred within 3- 9 weeks of cessation of treatment in 13 of the 18 patients who had initially shown an improvement or were healed in group I and in 7 of the 9 patients in group II. Topical tacrolimus 0.1% ointment induced a better initial therapeutic response than triamcinolone acetonide 0.1% ointment. However, relapses occurred frequently within 3- 9 weeks of the cessation of treatment.展开更多

Design: In group A (20 patients), the oral lesions were confined to areas in close contact with amalgam fillings. In group B (20 patients), the lesions extended 1 cm beyond the area of contact with amalgam fillings. In group C (20 patients), the oral lesions had no topographic relationship with amalgam fillings. Partial or complete replacement of amalgam fillings was recommended if there was a positive patch test reaction to ammoniated mercury, metallic mercury, or amalgam. Control group D (20 patients) had signs of allergic contact dermatitis. Results: Amalgam fillings were replaced in 13 patients of group A, with significant improvement. Dental amalgam was replaced in 8 patients of group B, with significant improvement. In group C, amalgam replacement in 2 patients resulted in improvement in 1 patient. These results were evaluated after 3 months. No positive patch test reactions to mercury compounds were found in patients with concomitant cutaneous lichen planus and in group D. Conclusions: Contact allergy to mercury compounds is important in the pathogenesis of oral lichen planus, especially if there is close contact with amalgam fillings and if no concomitant cutaneous lichen planus is present. In cases of positive patch test reactions to mercury compounds, partial or complete replacement of amalgam fillings will lead to a significant improvement in nearly all patients.展开更多
