periodontal microbiology ppt

From an ecologic viewpoint, the oral cavity, which communicates with the pharynx, should be considered as an “open growth system” with an uninterrupted ingestion and removal of microorganisms and their nutrients.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. (Gram-negative bacteria,short, pleomorphic rods) Fusobacterium sp. Genetic factors associated with periodontal diseases 11. Microbial interactionswith the host in periodontal diseases 7. Subgingival microflora and periodontal disease J Clin Periodontol. These bacteria are usually found together in periodontal pockets, suggesting that they may cause destruction of the periodontal tissue in a cooperative manner. Procedures such as dental scaling can radically alter the composition of the periodontal pocket flora of diseased sites and shift the balance in favour of colonization of such sites by flora that are associated with health.

Corn Cob Formation (Listgarten et al, 1973)– Central Gram Negative Filamentous Core Supports Outer Coccal Cells Which Are Firmly Attached By Inter-bacterial Adherence Or Coaggregation. A clear halo surrounding the colonies appears through hemolytic activity. Lancefield groups : A to V without I and T. In acute infections, an agent is acquired by exposure to an individual harbouring that agent or from the environment. Oral microbiology – Bacteriology of dental caries and periodontal diseases. Microbiology of. Clarus Dental Periodontal Disease Treatment Center - Periodontal disease is infection of the gums and if not treated on time can contribute to receding gums. Microbiology of dental caries . Pathogenesis of paque associated periodontal diseases 8. Bacteria were thought to be merely secondary invaders in this process or, at most, contributors to the inflammation observed in periodontal destruction. There is a perception of conflicting data and opinions among research laboratories that are studying periodontal microbiology. This host–pathogen interaction often is resolved within a short period of time, usually, but not always, in favour of the host. On this basis, a test to measure protease activity by degradation of the substrate N-benzoyl-dl-arginine-2-naphthylamide has been … Dewhirst FE, Chen T, Izara J, Paster BJ, Tanner AC, Yu WH, et al. 1880–1920), when the etiologic agents of many medically important infections were determined.

Scribd … Dr. Fletcher is currently the Assistant Dean for Graduate Student Affairs in the School of Medicine at Loma Linda University. Thus, daily experience suggests that colonization by a pathogen is rapidly followed by expression of disease. Anaerobic Gram-negative bacteria – Gram stain. Part 6: Cross-infection and control . In certain ways, periodontal diseases may be among the most unusual infections of the human.In contrast to the outer surface of most parts of the body, the outer layers of the tooth do not “shed” and thus microbial colonization (accumulation) is facilitated. The important role of spirochetes and fusiforms in Vincent’s infection was widely recognized in the succeeding 2 decades. Microbiology of Periodontal Diseases. There is a vast literature in periodontal microbiology based on these species.

Oral microbiology ppt دخول. Periodontal disease; ; Delivery Systems. They did demonstrate, however, that mixed infections were due to bacteria (rather than a virus).In other words, any combination of microorganisms capable of producing an array of destructive metabolites could lead to transmissible infections in animals and, by extension, to destructive periodontal infections in humans. A “battle” occurs between the parasite and the host resulting in increasingly obvious clinical signs and symptoms. Later investigators failed to reproduce their results either with the above combination of microorganisms or with many other combinations they tested. 37. While certain infections follow this pattern, more commonly, colonization by a pathogenic species does not lead to overt disease, at least immediately. The soft tissue surfaces employ a variety of mechanisms to prevent adhesion of pathogenic organisms. Clipping is a handy way to collect important slides you want to go back to later. Twenty-four patients (10 males and 14 females, aged 14.6 ± 1.0 years) were included in this investigation. Basic concepts of immunity and inflammation 6.

Individual Micro colonies can consist of single species but are frequently composed of several different species. The proposal of the “ecological plaque hypothesis” in 2003 was a significant development in the conceptual understanding of the subgingival environment and how the local environment can influence bacterial composition.
