Periodontitis is a globally widespread pathology of the human oral cavity. Smoking, through dysfunction of antioxidant system, plays an important role in the pathogenesis of inflammatory diseases.The current study aimed at comparing salivary antioxidant capacity in smokers and non-smokers with severe chronic periodontitis.In this case-control study, among patients referred to … The gums will pull back from the teeth and eventually teeth will loosen and fall out. After that the bacterial activation of immuno inflammatory mechanisms, environmental and genetic factors modified the clinical phenotype of periodontal disease which led to the formulation of non-linear conceptual models. Gingivitis as a risk factor in periodontal disease. It results from interaction between bacterial, environmental, immunologic and genetic factors. 2000 Jul;44(3):633-58. 2. Deo V, Bhongade ML. USA.gov. The characteristic clinical signs of chronic periodontitis occur mainly as a result of activation of host-derived immune and inflammatory defense mechanism. Histopathological lesions of periodontal pathogenesis. The involvement of neutrophils in the pathogenesis of a chronic disease such as periodontitis may appear surprising, given that they are generally associated with the acute host response to infections. 2020 Jun;83(1):213-233. doi: 10.1111/prd.12329. Therefore, they have immunoregulatory properties and promote cell proliferation and tissue regeneration [29, 34]. Regional lymph node enlargement. In the alveolar bone, the RANKL/OPG/RANK system controls the balance of the bone metabolism . Pathogenesis of acute (a,b), chronic (c), and cystic (d,e) apical periodontitis (AP) lesions. 2020 Jun 3;11:1108. doi: 10.3389/fimmu.2020.01108. Contents Pathophysiology Edit Chronic periodontitis is initiated by Gram-negative tooth-associated microbial biofilms that elicit a host response, which results in bone and soft tissue destruction. It can occur independently vnas lidok microtrauma, chronic pulpitis or after treatment e pulpitis, but often the disease develops after treatment of other chronic forms of periodontitis. It's usually the result of poor oral hygiene. Candidate gene polymorphism studies with a case-control design and reported … The inflammatory immune response is triggered by the interaction of resident cells with the bacterial biofilm attached to the tooth surface. Gingiva is a portion of the oral mucosa covering the tooth-carrying part of the alveolar bone and the cervical neck of the tooth. (b) Forms of cementum: acellular afibrillar cementum (AAC), acellular extrinsic fibers cementum (AEFC), cellular mixed stratified cementum (CMSC), and cellular intrinsic fibers cementum (CIFC). Hence an inflammation in In addition, the root cementum plays important roles in nourishing the tooth as well as in stabilizing the tooth via the attachment to the periodontal ligament. Chronic periodontitis formerly known as “adult periodontitis “ or “chronic adult periodontitis” is the most prevalent form of periodontitis Although it is most frequently seen in adults, but in some cases can also be present in children and in adolescents in response to chronic plaque and calculus accumulation. Aquino-Martinez R, Khosla S, Farr JN, Monroe DG. Hajishengallis G, Chavakis T, Lambris JD. Its integrity is thus essential for maintaining a healthy periodontium. Three parts of the gingiva can be distinguished (e.g., Figure 1d): (1) free gingiva (FG), (2) interdental gingiva (IG), and (3) attached or inserted gingiva (AG) . How? Clinically detected gingival overgrowth is one of the alterations that occurs in chronic periodontitis. The alveolar bone, together with the root cementum and the periodontal ligament, constitutes the tooth insertion apparatus, whose main function is to distribute the forces generated by chewing and other contacts . There are polymorphonuclear leukocytes and monocytes that pass from the subepithelial connective tissue through the junctional epithelium and into the gingival sulcus. A consideration of currently available data has permitted the formulation of a new concept of the pathogenesis of this disease. Pathogenesis of chronic periodontitis The role of host immune system in periodontal pathogenesis involves the following in response to bacterial infection 5 (Fig. Introduction. The pathogenesis of apical periodontitis involves an encounter at the periapex between the microbial and host factors (fig. The junctional epithelium plays a crucial role since it essentially seals off periodontal tissues from the oral environment. Over the years, our understanding of the pathogenesis of periodontitis changed from one being an infectious disease of solely bacterial origin to the one being a non-resolving inflammatory process to a diverse group of dysbiotic microbial species which is driven by genetic, environmental, local, and systemic factors. Chronic adult periodontitis is a bacterially induced chronic inflammatory disease that destroys the connective tissue and bone that support teeth. PATHOGENESIS Apical periodontitis may be acute (symptomatic) or chronic (asymptomatic). 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.

After that the bacterial activation of immuno inflammatory mechanisms, environmental and genetic factors modified the clinical phenotype of periodontal disease which led to the formulation of non-linear conceptual models. Preianò M, Savino R, Villella C, Pelaia C, Terracciano R. Int J Mol Sci. 2020 Oct;84(1):14-34. doi: 10.1111/prd.12331. INTRODUCTION: The pathogenesis ofperiodontitis has not been completely defined, therefore the study was aimed at evaluating combined effects of environmental factors as well as interleukin-1beta (IL-1beta) and FcgammaRIIa genotypes on the risk of periodontal disease. Journal of Clinical Pe riodontology. dental plaque. The main function of the periodontium is to join the tooth to the bone tissue and maintain integrity on the surface of the masticatory mucosa of the oral cavity . | Karla Mariana Chávez-Ruvalcaba, Dra. Over time, plaque builds up and eventually leads to periodontitis. Understanding periodontal pathogenesis is key to improving management strategies for this common, complex disease. DOI: 10. It is a complex disease with multifactorial etiology. It is characterized by a conversion of junctional epithelium to the pocket epithelium, formation of denser inflammatory infiltrate composed of plasma cells and macrophages, loss of collagen attachment to the root surface, and resorption of the alveolar bone [6, 11, 12, 13]. en C.
