Chronic periodontitis, a common disease of microbial origin, is the major cause of tooth loss in adult humans. Pathogenesis of periodontitis 1. The major components of chronic lesions (c) are lymphocytes (Ly), plasma cells (Pc), and macrophages (Ma). This represents an attempt by the body to enhance mechanical barrier protection to plaque bact.

It can result in irreversible loss of periodontal attachment and destruction of adjacent alveolar bone leading to increased tooth mobility and finally to exfoliation. The pathogenesis of periodontitis involves a complex immune/inflammatory cascade that is initiated by the bacteria of the oral biofilm that forms naturally on the teeth. model of periodontitis pathogenesis to the one illus-trated in Fig. 1 of 7 Introduction – 1:09 minutes. Those models included the bacterial activation of immunoinflammatory mechanisms, some of which targeted control of the bacterial challenge and others that had adverse effects on bone and connective tissue remodeling. 2.

Pathogenesis of periodontitis: a major arginine-specific cysteine proteinase from Porphyromonas gingivalis induces vascular permeability enhancement through activation of the kallikrein/kinin pathway. Chronic periodontitis is an inflammatory destruction of tooth supporting structures that, if left untreated, may lead to tooth loss.1, 2 Chronic periodontitis is the most prevalent inflammatory disease worldwide. The susceptibility to periodontitis appears to be determined by the host response; specifically, the magnitude of the inflammatory response and the differential activation of immune pathways.

Microbial invasion – the invasion of dentogingival complex by spirochetes was documented by lisgarten. The association of bacteria within mixed biofilms is not random, rather there are specific associations among bacterial species. 3). Looks like you’ve clipped this slide to already.

Periodontal disease is an inflammatory disease of the gum caused by a formation of a plaque that triggers immune responses and inflammation leading to the destruction of tissues surrounding and supporting the teeth. The 2017 World Workshop on the Classification of Periodontal and Peri-implant Diseases and Condition identified the gingivitis case by the presence of gingival inflammation at one or more sites and agreed upon bleeding on probing as the primary parameter for diagnosis of gingivitis. dental plaque. This lesson will take you through the various stages, from the initial plaque deposits, to gingivitis and eventually periodontitis. Aggressive periodontitis describes a type of periodontal disease and includes two of the seven classifications of periodontitis as defined by the 1999 classification system:.

There was no significant difference between the subjects with periodontal disease and those with healthy gingival tissues either in serum IL-6 levels or in the amount of IL-6 produced by PBMC. While periodontitis deteriorates patients’ quality of life, non-surgical periodontal treatment seems to offer an improvement. Moreover, it aims to review the association of these IMIDs with periodontitis and briefly discusses the therapeutic potential of agents that modulate the IL-17/IL-23 axis. Periodontitis can cause teeth to loosen or lead to tooth loss. The cells occur as Th1 and Th-2 cells.
