Necrotizing gingivitis (NG) is a common, non-contagious infection of the gums with sudden onset. The main features are painful, bleeding gums, and ulceration of interdental papillae (the sections of gum between adjacent teeth).
Necrotizing gingivitis: painful, bleeding, sloughing ulceration and loss of the interdental papillae (usually of the lower front teeth) Necrotizing gingivitis, is a common, non-contagious infection of the gums. If improperly treated necrotizing may become chronic and/or recurrent.
The milder form, necrotizing ulcerative gingivitis (also termed "trench mouth"), [9] is characterized by painful, bleeding gums and ulceration and necrosis of the interdental papilla. There may also be intra-oral halitosis , cervical lymphadenitis (swollen lymph nodes in the neck) and malaise .
Periodontitis as a manifestation of systemic diseases is one of the seven categories of periodontitis as defined by the American Academy of Periodontology 1999 classification system and is one of the three classifications of periodontal diseases and conditions within the 2017 classification.
Gingivitis is a non-destructive disease that causes inflammation of the gums; [1] ulitis is an alternative term. [2] The most common form of gingivitis, and the most common form of periodontal disease overall, is in response to bacterial biofilms (also called plaque) that are attached to tooth surfaces, termed plaque-induced gingivitis.
The most common gingival disease is gingivitis, the earliest stage of gingival-related diseases. Gingival disease encompasses all the conditions that surround the gums, this includes plaque-induced gingivitis, non-dental biofilm plaque-induced gingivitis, and periodontal diseases .
The term "full width gingivitis" usually refers to the oral lesions of orofacial granulomatosis however. [4] The color is another dissimilarity between typical marginal gingivitis and desquamative gingivitis, in the latter it is dusky red. [3] Plasma cell gingivitis is another form of gingivitis which affects both the attached and free gingiva. [1]
Prevotella intermedia (formerly Bacteroides intermedius) is a gram-negative, obligate anaerobic pathogenic bacterium involved in periodontal infections, including gingivitis and periodontitis, and often found in acute necrotizing ulcerative gingivitis. It is commonly isolated from dental abscesses, where obligate anaerobes predominate.
