Treponema denticola is a Gram-negative, obligate anaerobic, motile and highly proteolytic spirochete bacterium. It is one of four species of oral spirochetes to be reliably cultured, the others being Treponema pectinovorum, Treponema socranskii and Treponema vincentii [ 2 ] .
Chronic periodontitis is prevalent in adults and seniors worldwide. In the US around 35% of adults (30–90 years) are affected. [1] The cumulative effects of alveolar bone loss, attachment loss and pocket formation is more apparent with an increase in age. Age is related to the incidence of periodontal destruction: "...in a well-maintained ...
Periodontal disease typically arises from the development of plaque biofilm, which harbors harmful bacteria such as Porphyromonas gingivalis and Treponema denticola. These bacteria infect the gum tissue surrounding the teeth, leading to inflammation and, if left untreated, progressive damage to the teeth and gum tissue. [9]
If improperly treated necrotizing may become chronic and/or recurrent. In developed countries, necrotizing gingivitis occurs mostly in young adults with predisposing factors such as psychological stress, sleep deprivation, poor oral hygiene, smoking, immunosuppression and/or malnutrition. In developing countries, necrotizing gingivitis occurs ...
With an increase in the age of the patient, there may be progression of the disease involving the adjacent teeth and lead to the patient developing GAP. [ 34 ] [ 17 ] The periodontal tissue also exhibits minimal signs of inflammation clinically [ 35 ] and show a robust response with serum antibodies to pathogens.
Treponema is a genus of spiral-shaped bacteria. The major treponeme species of human pathogens is Treponema pallidum, whose subspecies are responsible for diseases such as syphilis, bejel, and yaws. Treponema carateum is the cause of pinta. [2] Treponema paraluiscuniculi is associated with syphilis in rabbits. [3]
“In adults over the age of 65, symptoms almost always include a cough, whereas with the flu, coughing is usually just present in about two-thirds of patients,” he says. He explains that the ...
Necrotizing periodontal diseases are caused by a mixed bacterial infection that includes anaerobes such as P. intermedia [1] and Fusobacterium as well as spirochetes, such as Treponema. [ 3 ] Necrotizing gingivitis may also be associated with diseases in which the immune system is compromised, including HIV/AIDS. [ 1 ]
