A clinically hidden but severely destructive entity.

The diagnosis' Aggressive Periodontitis' (AgP), defined by the International workshop for a classification of periodontal diseases and conditions in 1999, refers to the multifactorial, severe and rapidly progressive form of periodontitis, which primarily--but not exclusively--affects younger patients. Direct and indirect bacterial effects influencing the host immune response play a significant part in the aetiology of AgP comparable with chronic periodontitis. In addition to various virulence factors of specific periodontal pathogens, a genetic predisposition influences the outbreak and progression of the disease. This report describes the disciplinary treatment of AgP patient with progressing full-mouth bone resorption.
