Epulis Fissuratum
Pronunciation: ep-YOO-lis fis-yoo-RAH-tum
A benign hyperplastic tissue reaction of the oral mucosa, characterised by fibrous folds or flaps of tissue forming around the flanges of an ill-fitting denture.
Full Definition
Epulis fissuratum, also known as denture-induced fibrous hyperplasia or inflammatory fibrous hyperplasia, is the most common reactive lesion associated with denture wearing. The chronic trauma from an overextended or loose denture flange stimulates reactive fibrous proliferation, producing one or more folds of firm, pink tissue. Histologically, the tissue shows fibrous hyperplasia with variable inflammation. Editors should note that it is distinct from denture stomatitis (erythematous candidiasis under a denture) and from irritation fibroma. The preferred modern term in some classifications is 'denture-induced fibrous hyperplasia.'
Usage
Usage note: The Latin plural is 'epulides fissurata'; editors should not write 'epulis fissuratums.' Distinguish from 'denture stomatitis,' which is an erythematous mucosal candidal infection beneath the denture base, not a fibrous proliferation.
