Foreign Body Gingivitis.

Foreign body gingivitis (FBG) is a non-plaque induced chronic inflammatory process involving the marginal and/or attached gingiva. It results from the introduction of foreign particulate material, primarily dental prophylaxis paste and restorative dental materials, into the gingival tissues. Clinical presentation varies from an erythematous to vesiculoerosive-like process that may mimic a localized form of desquamative gingivitis or an erosive lichenoid process. Rarely, it may also present with a granular appearance. We describe the clinical presentation, differential diagnosis and clinical management of a 52-year-old Woman who presented with localized chronic inflammation of the maxillary anterior and left posterior gingiva secondary to the presence of foreign material.
