Treatment of gingival lichen with free palatal grafts

BACKGROUND: Recalcitrant gingival erythematous lichen planus/lichenoid lesions comprise a considerable therapeutic problem. The objective of this study was to evaluate the therapeutic effect of grafting keratinized oral palatal mucosa to the sites of gingival lichen. METHODS: In 12 patients 20 grafts were transplanted to buccal gingival lesions. Mean age of the patients was 59.8 +/- 7.1 years (range 46-71 years). The mean observation time was 32 +/- 32.7 months (range 5-97 months). RESULTS: On a 4-point clinical grade scale (0-3), 12 (60%) transplants showed complete healing grade 3, six (30%) grade 2 and two (10%) grade 1. CONCLUSIONS: Using oral mucosal grafts from the palatal mucosa for the treatment of recalcitrant erythematous gingival lichen planus/lichenoid lesions seems to be a promising treatment modality.
