gingivitis

 [jin″jĭ-vi´tis]
inflammation of the gums. Bleeding is a primary symptom, and other symptoms include swelling, redness, pain, and difficulty in chewing. Gingivitis can lead to the more serious disorder known as periodontitis. There are numerous causes, of which the primary one is pathogenic microorganisms in the crevices between the gums and the teeth. Other contributing factors are general poor health, host response to inflammation, hormonal imbalances, malnutrition, reactions to certain medications, irregular teeth, badly fitting fillings or dentures that irritate the gums, systemic disease, and infections such as herpetic gingivostomatitis. Gingivitis is best prevented by correct brushing and flossing of the teeth and proper oral hygiene. A good diet containing the necessary minerals and vitamins is also important. Vitamin deficiencies and anemia and other blood dyscrasias are often accompanied by gingivitis.
acute necrotizing ulcerative gingivitis (ANUG) (acute ulcerative gingivitis) necrotizing ulcerative gingivitis.
Dilantin gingivitis generalized hyperplasia of the gingiva, which may also rarely involve other areas of the oral mucosa, resulting in overgrowth of the fibrous tissue from the interaction of plaque accumulation with the anticonvulsive agent Dilantin (phenytoin).
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 (see also vincent's angina). The etiology is uncertain, but many authorities believe 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 (HIV). Although the disease often occurs in an epidemic pattern, it has not been shown to be contagious. Called also acute necrotizing ulcerative or acute ulcerative gingivitis.
pregnancy gingivitis any of various gingival changes ranging from gingivitis to the so-called pregnancy tumor.
Vincent's gingivitis necrotizing ulcerative gingivitis.

nec·ro·tiz·ing ul·cer·a·tive gin·gi·vi·tis (NUG),

an acute or recurrent gingivitis of young and middle-aged adults characterized clinically by gingival erythema and pain, fetid odor, necrosis, and sloughing of interdental papillae and marginal gingiva that gives rise to a gray pseudomembrane; fever, regional lymphadenopathy, and other systemic manifestations also may be present. A fusiform bacillus and Treponema vincentii can be isolated from the gingival tissues in large numbers and are thought to play a significant but poorly defined role in the pathogenesis.

acute necrotizing ulcerative gingivitis (ANUG),

a recurrent periodontal disease of sudden onset that primarily affects the interdental papillae. It is characterized by painful inflammation and ulceration of the gums, leading to the formation of craterlike defects and ulcers. The necrotic tissue appears as a gray membrane that is easily sloughed off. There also may be fever, bone destruction, a fetid odor, and enlarged lymph nodes in the throat and neck. It is usually associated with poor oral hygiene and stress and is most common in conditions in which there is crowding of the teeth and malnutrition. Treatment includes chlorhexidine mouthwashes, antibiotics, analgesics, and dental care to remove and disrupt bacterial flora. Also called trench mouth, Vincent's angina, Vincent's infection. See gingivitis.
A form of gingivitis, first described in World War I when it was common among soldiers
Aetiology Opportunistic overgrowth of oral flora, resulting in painful ulcers, most common in young adults
Risk factors Poor oral hygiene, poor nutrition, infections, smoking, emotional stress

(NUG) (nek'rō-tīz-ing ŭl'sĕr-ă-tiv jin'ji-vī'tis)
An acute or recurrent gingivitis of young and middle-aged adults characterized clinically by gingival erythema and pain, fetid odor, and necrosis and sloughing of interdental papillae and marginal gingiva that give rise to a gray pseudomembrane; fever, regional lymphadenopathy, and other systemic manifestations also may be present. A fusiform bacillus and Treponema vincentii can be isolated from the gingival tissues in large numbers and are considered to play a significant but poorly defined role in the pathogenesis.
