Necrotizing periodontal diseases are a type of inflammatory periodontal (gum) disease caused by bacteria (notably fusobacteria and spirochaete species). The diseases appear to represent different severities or stages of the same disease process, although this is not completely certain. These diseases usually have a sudden onset.
Acute necrotizing ulcerative gingivitis: painful, bleeding, sloughing ulceration and loss of the interdental papillae (usually of the lower front teeth). Necrotizing periodontal diseases are non-contagious infections but may occasionally occur in epidemic-like patterns due to shared risk factors.
Necrotizing gingivitis is part of a spectrum of disease termed necrotizing periodontal diseases. It is the most minor form of this spectrum, with more advanced stages being termed necrotizing periodontitis, necrotizing stomatitis, and the most extreme, cancrum oris.
Periodontal disease, also known as gum disease, is a set of inflammatory conditions affecting the tissues surrounding the teeth. [5] In its early stage, called gingivitis, the gums become swollen and red and may bleed. [5] It is considered the main cause of tooth loss for adults worldwide.
The symptoms range from a minor nuisance to being disabling in their impact on eating, swallowing, and talking, and the severe forms can cause people to lose weight. There is no cure for aphthous stomatitis, [ 5 ] and therapies are aimed at alleviating the pain, reducing the inflammation and promoting healing of the ulcers, but there is little ...
Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle. [2] The soft tissue covering a partially erupted tooth is known as an operculum, an area which can be difficult to access with normal oral hygiene methods.
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.
Classification of Periodontal Diseases 2018. In 2018, a new classification system for Periodontal diseases was released. It has 3 main parts: Periodontal health, gingival diseases and conditions; Periodontitis; Other conditions affecting the periodontium. In periodontal health, gingival diseases and conditions, there are 3 sub-types: [5]
