Dental plaque mediated periodontal disease, Recent data from a number of laboratories propose that different types of periodontal disease. The aim of this review paper is to highlight the oral microbial ecosystems in oral health and disease and to investigate the ecological changes that shift the indigenous bacteria residing dental plaque to be increased in number and cause oral diseases. the alveolar bone, connective tissue attachment, and gingiva . Molecular analysis of oral microbial communities has indicated that the human mouth provides a habitat for approximately 700 species of bacteria.The oral cavity is somewhat unique, since it provides hard, nonshedding surfaces (teeth) that are accessible for microbial colonisation. of choice because of its universal presence in all organisms.

The stages of plaque biofilm formation include acquired pellicle formation; reversible adhesion, involving weak long-range physicochemical interactions between the cell surface and the, pellicle, which can lead to stronger adhesin-receptor mediated attachment; co-adhesion, resulting in attachment of secondary colonizers to already attached cells; and formation of.

Gingival crevicular fluid (GCF) was collected from a healthy, a gingivitis and a periodontitis site in 18 subjects with periodontitis and from a healthy site in, Subgingival restorative margins are associated with the development of plaque-related inflammatory periodontal disease, primarily because of a shift in the subgingival microflora from a profile associated with health to one associated with disease. In P. gingivalis-administered mice blood endotoxin levels tended to be higher, whereas gene expression of tight junction proteins in the ileum was significantly decreased. Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia form a consortium in the subgingival biofilm and are regarded as the principal periodontopathogenic bacteria. Drug resistance developed by oral microbes and further side effects pose serious hurdles in the current therapeutic strategies. Oral microorganisms live in biofilm. odontal disease and is more severe in individuals with poor oral hygiene .
