Chronic Presence of Epstein Barr Virus in Epithelial Cells From Gingiva is Associated With Periodontitis

17. december 2012 opdateret af: Centre Hospitalier Universitaire de Nice
The etiopathogenesis of periodontal disease results from complex interaction between infectious agents, mainly including bacteria, and host cellular and humoral immune responses. However it is thought that bacteria-induced pathogenesis is not sufficient alone to explain all biological and clinical features of the destructive periodontal disease. The main hypothesis is that herpesviruses, such as Epstein-Barr Virus, may participate as well by altering epithelial gingival cell biology and consequently may promote the initiation and progression of periodontitis.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: kronisk paradentose
Procedure: dental root planing
The objective of root planing, otherwise known as conventional periodontal therapy, non-surgical periodontal therapy, or dental prophylaxis is to remove or eliminate the etiologic agents which cause inflammation: dental plaque, its products and calculus,[1] thus helping to establish a periodontium that is free of disease.[2]
