models of pathogenesis of periodontal disease

25. … Chemokine function in periodontal disease and oral cavity cancer. Selection of the appropriate animal model depends on the similarity of the periodontium and the nature of the disease to that of humans. System includes a person level, a genetic/epigenetic level, the biologic phenotype, and ultimately the clinical phenotype 54. Van Dyke TE, van Winkelhoff AJ. However, the models did not capture the dynamic nature of the biochemical processes, i.e., that innate differences among individuals and changes in environmental factors may accelerate biochemical changes or dampen that shift. Periodontal diseases are among the most common infectious diseases in humans, and the primary cause of tooth loss in adults. Advanced mechanisms regarding the pathogenesis of periodontal disease have been developed due to the introduction of new technologies and expanding knowledge in the field of microbiology and genetics. Chronic periodontitis is a multifactorial disease. observations described linear model of pathogenesis in periodontal disease. Abstract. Front Immunol. PubMed Google Scholar. However, each model examined does vary from the human condition. 2013;84(Suppl 4):S1–7. The disease serves as a convenient experimental model for analysis of many aspects of chronic inflammation. In regards to inclusive dates, published studies from January 2006 to December 2015 were considered in this review along with the mentioned inclusion criteria. Introduction. A consideration of currently available data has permitted the formulation of a new concept of the pathogenesis of this disease. Infection and inflammatory mechanisms. 2003;82(2):82–90. 1.3. used to study different aspects of periodontal diseases. PubMed Google Scholar. Animal models are needed to objectively evaluate the pathogenesis of human periodontal diseases and its various treatment modalities. The functional and esthetic problems associated with these diseases compromise quality of life, and their treatment imposes large financial burdens on national health systems and private patients. The knowledge of how immune mechanisms and inflammatory responses are regulated is fundamental to understanding the pathogenesis of periodontal disease. Although cultured cells can be used to study physiological processes that occur during the pathogenesis of periodontitis, the complex host response fundamentally responsible for this disease cannot be reproduced in vitro .

Nonhuman Primates. Sahingur SE, Yeudall WA. P.gingivalis, a Gram-negative black-pigmented microorganism, has been implicated as the major pathogen in the development of adult periodontitis, and the intimate interaction of this periodontal pathogen with the host has become a subject of intense investigation. There is no doubt that animal models of disease are, and continue to be, necessary for the elucidation of the details of the pathogenesis of human periodontal disease. The first challenge is to understand exactly what is meant by the term pathogenesis. Potential mechanisms by which systemic inflammation and infectious challenge of periodontal origin may serve as a potential modifier of cardiovascular disease are discussed in the context of a detailed working model of pathogenesis. Such models also acknowledged that different environmental and genetic factors modified the clinical phenotype of periodontal disease. animal experimental models of periodontal disease were included in the discussion. The placebo group was only administrated to normal dog chow (25 g/kg/day). The most common periodontal diseases are gingivitis and periodontitis, whose main characteristic is inflammation. Disease model was induced in 20 male and female dogs. The core elements of the classical model of disease pathogenesis, developed by Page & Kornman in 1997, remain … The past decade of basic research in periodontology has driven radical changes in our understanding and perceptions of the pathogenic processes that drive periodontal tissue destruction. In Fernando José de Oliveira Nóbrega, Denise Hélen Imaculada Pereira de Oliveira, Rodrigo Gadelha Vasconcelos, Cassiano Francisco Weege Nonaka, Lélia Maria Guedes Queiroz, Study of the participation of MMP-7, EMMPRIN and cyclophilin A in the pathogenesis of periodontal disease, Archives of Oral Biology, 10.1016/j.archoralbio.2016.08.032, 72, (172-178), (2016). Resolution of inflammation: a new paradigm for the pathogenesis of periodontal diseases. We know little, however, about the initiating stage of dysbiosis that leads to disease progression. Such models also acknowledged that different environmental and genetic factors modified the clinical phenotype of periodontal disease. Further examination of the intricacies of each model will be necessary to allow interpretation of experimental results. periodontal disease pathogenesis is that the periodontitis-associated microbiotas in mice and humans differ considerably. A REVIEW ON MODELS OF PATHOGENESIS IN PERIODONTITIS. In Genome Medicine, Yost et al. Our understanding of the pathogenesis of periodontal diseases has greatly progressed over the past three decades. - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Periodontal disease (PD) refers to a group of inflammatory diseases caused by bacterial plaque in the periodontium. Animal models can provide critically important information regarding periodontal disease pathogenesis and have been widely used to establish cause-and-effect relationships and for investigating the efficacy of new treatments. Biologic systems model Represents periodontal pathogenesis, which involves bacterial components, environmental factors, specific inflammatory mechanisms, and host-genetic variations associated with disease. models of periodontal disease have contributed new knowledge to the biologic sciences. The current model of periodontal disease progression proposes that changes in periodontal microbiota, or dysbiosis, de-regulate the host immune response, leading to chronic inflammation. J Periodontol. Nonhuman primates have oral structures and teeth similar to those of humans and have naturally occurring dental plaque, calculus, oral microbial pathogens (e.g., P. gingivalis), and periodontal disease. J Dent Res. After a 12-week induction of periodontitis, animals were assigned to a placebo, positive control (doxycycline), and two treatment groups consisting of five animals each. Periodontal disease, or periodontitis, is a globally widespread pathology of the human oral cavity. Animal models and cell cultures have contributed new knowledge in biological sciences, including periodontology. 26. phyromonas gingivalis and animal models to study periodontal disease pathogenesis. This model explains various factors responsible for periodontal disease progression; however, some of the concepts in this model have become obsolete in the recent scenario leading to the development of advanced models for progression of periodontal disease. The staging of periodontal disease pathogenesis as 'initial', 'early', 'established' and 'advanced' lesions productively guided subsequent research in the field and remains fundamentally valid.
