necrotizing ulcerative gingivitis (NUG),

an inflammatory destructive disease of the gingivae that has a sudden onset with periods of remission and exacerbation. It is marked by ulcers of the gingival papillae that become covered by sloughed tissue and circumscribed by linear erythema. Fetid breath, increased salivation, and spontaneous gingival hemorrhage are additional features. It may extend to other parts of the oral mucosa, with lesions involving the palate or pharynx. The cause is uncertain, but many authorities believe that it is caused by a bacterial complex in the presence of predisposing factors, such as preexisting gingival disease, smoking, severe stress, radical changes in eating or sleeping patterns, or nutritional deficiency. It has also been associated with immunodeficiency conditions, such as infection with the human immunodeficiency virus. Although the disease often occurs in an epidemic pattern, it has not been shown to be contagious. Also called acute necrotizing ulcerative gingivitis, acute ulcerative gingivitis.

gingivitis (jin´jivī´tis),

n an inflammation of the gingival tissue. A major classification of periodontal disease.

Gingivitis.

gingivitis and malposed teeth,

n the malposition may predispose the gingivae to inflammation by permitting food impaction or impingement, by providing irregular spaces in which calculus may be deposited, and by making oral hygiene difficult.

gingivitis, bacteria in,

n the causative organisms in gingival inflammation. The common chronic forms of gingivitis, from a bacterial standpoint, are nonspecific, with the exception of acute necrotizing ulcerative gingivitis, in which there is an apparent specificity of the bacterial flora: the fusospirochetal organisms.

gingivitis, bismuth,

n a metallic poisoning caused by bismuth given for treatment of systemic disease; characterized by a dark, bluish line along the gingival margin.

gingivitis, chronic atrophic senile,

n gingival inflammation characterized by atrophy and areas of hyperkeratosis; found primarily in elderly women.

gingivitis, desquamative

n an inflammation of the gingivae characterized by a tendency of the surface epithelium to desquamate. The disease is a clinical entity, not a pathologic entity. It is most frequently associated with menopause but may be associated with biologic stress. Older term: gingivosis.

gingivitis, eruptive

n the gingival inflammation occurring at the time of eruption of the primary or permanent teeth.

gingivitis, fusospirochetal,

n See gingivitis, necrotizing ulcerative.

gingivitis gravidarum,

n See gingivitis, pregnancy.

gingivitis, hemorrhagic,

n the gingivitis characterized by profuse bleeding, especially that associated with ascorbic acid deficiency or leukemia.

gingivitis, herpetic,

n an inflammation of the gingivae caused by herpesvirus. See also gingivostomatitis, herpetic.

gingivitis, hormonal,

n the gingivitis associated with endocrine imbalance, the endocrinopathy being modified, in most instances, by the influence of local environmental factors.

gingivitis, hyperplastic,

n the gingivitis characterized by proliferation of the various tissue elements. May be accompanied by dense infiltration of inflammatory cells.

gingivitis, idiopathic,

n a gingival inflammation of unknown causation.

gingivitis, infectious,

n a gingivitis not caused by plaque, but instead originating from bacteria, fungi, or viruses.

gingivitis, inflammatory cells in,

n the inflammatory cells are, for the most part, lymphocytes, plasma cells, and some histiocytes, because the gingival inflammatory process is usually chronic and progressive in nature. With acute exacerbations, polymorphonuclear leukocytes are also present.

gingivitis, marginal,

n an inflammation of the gingivae localized to the marginal gingivae and interdental papillae.

gingivitis, menstrual cycle associ-ated,

n gingival inflammation that occurs during ovulation as a result of hormone-level changes.

gingivitis, necrotizing ulcerative,

n (fusospirochetal gingivitis, NUG, trench oral cavity, ulcerative gingivitis, ulceromembranous gingivitis, Vin-cent's gingivitis, Vincent's infection) a form of necrotizing periodontal disease with an inflammation of the gingivae characterized by necrosis of the interdental papillae, ulceration of the gingival margins, the appearance of a pseudomembrane, pain, and a fetid odor.

n (uremic gingivitis, uremic stomatitis), a membrane form of stomatitis and gingivitis associated with a failure of kidney function. It is accompanied by pain, ammonia-like odor, and increased salivation.

gingivitis, non plaque-induced,

n a gingivitis caused by factors other than plaque, such as allergic reaction, dermatologic disease, a genetic condition, infectious agents, response to a foreign body, or physical trauma.

gingivitis, plaque-induced,

n a gingivitis caused by the accumulation of plaque.

gingivitis, pregnancy,

n (gingivitis gravidarum, hormonal gingivitis), an enlargement of hyperplasia of the gingivae resulting from a hormonal imbalance during pregnancy.

Pregnancy gingivitis.

gingivitis, puberty,

n an enlargement of the gingival tissues as a result of an exaggerated response to irritation resulting from hormonal changes.

gingivitis, scorbutic,

n a gingivitis associated with vitamin C (ascorbic acid) deficiency.

gingivitis, systemic disease-induced,

n a gingivitis occurring as a complication of a systemic disease, such as type 1 diabetes mellitus or acute leukemia.

gingivitis, uremic,

n See gingivitis, nephritic.

gingivitis

a general term for inflammation of the gums, of which bleeding is one of the primary signs. Other signs include swelling, redness, pain and difficulty in chewing. There are numerous causes for this condition, and it can lead to a more serious disorder, periodontitis. One of the most common causes of gingivitis is the accumulation of food particles in the crevices between the gums and the teeth.

feline plasma cell gingivitis-pharyngitis, feline plasma cell-lymphocytic gingivitis-pharyngitis

a chronic inflammatory disease of the mouth in cats, characterized by proliferative and ulcerative lesions of the gums and palatine fossa. There is often anorexia and a fetid odor to the breath. The cause is unknown.

necrotizing ulcerative gingivitis

a gingival infection marked by redness and swelling, necrosis, pain, hemorrhage, a necrotic odor and often a pseudomembrane. Extension to the oral mucosa is called necrotizing ulcerative gingivostomatitis.

necrotizing

causing necrosis; exuding a brown to green, putrid discharge containing tissue debris.

disease of shrimps caused by a small obligate intracellular unidentified bacterium; subacute to chronic syndrome with cumulative mortality of up to 90%.

necrotizing panniculitis

multifocal, erythematous, nonpruritic cutaneous lesions which ulcerate in the center and discharge seropurulent exudate; identifiable on histopathological examination.

a rare eye lesion, inflammatory proliferation of the anterior sclera, in dogs.

necrotizing vasculitis

important feature of the Arthus reaction; damage to the endothelium results from deposition of immune complexes in the vessel wall, usually on the basement membrane of the endothelium.
