[Clinical and histologic analysis of mucous membrane lesions associated with dental restoration]

Fifteen cases of mucous membrane lesions associated with dental restorations were reported. Eleven cases appeared as lichen planus-like lesions clinically, three leukoplakia like lesions and one erythema with ulceration. Biopsies were taken in six cases, five of them were lichen planus, histologically like and epithelial dysplasia was present in one case. All lesions disappeared or improved after the amalgam restorations were changed. Diagnosis and differential diagnosis were discussed.
