The granulomatous response and oral cavity.

ABSTRACT

The granulomatous response is a phylogenetically primitive specialized immunological reaction of the body to wall off an irritant, ingest and remove it, characterised by a localized collection of epithelioid cells, macrophages and lymphocytes. The cells forming the granuloma, its mechanism of formation and types of granuloma have been discussed. A classification of granulomatous diseases of the oral cavity based on etiology has been suggested.
