Abstract
Fibrotic gingival enlargements induced by phenytoin or nifedipine were examined with special reference to type VI collagen expression. Immuno‐localization studies showed abnormal accumulation of type VI collagen around the collagen fiber bundles in the fibrotic gingival enlargements. Examination of total RNA extracted from fibroblasts and tissues of enlarged gingivae demonstrated increased type VI collagen steady‐state mRNA levels. These results suggest that excessive deposition of type VI collagen in drug‐induced gingival enlargement is attributed to increased expression of the collagen genes.Keywords
