Global Journal of Infectious Diseases and Clinical Research Citation: Silva L (2015) A Literature Review of Inlammation and Its Relationship with the Oral Cavity. Glob J Infect Dis Clin Res 1(1): 021-027. 021 Abstract Objective: This article presents a literature review which relates the processes, interactions, classiication and the vascular and clinical characteristics of inlammation relating it with the oral cavity and describing the main cell types and chemical mediators used for its establishment. Materials and Methods: it was used as source of research the following databases: MEDLINE, LILACS, BBO, Cochrane Library, Scielo, PubMed and the database of CAPES. Results: much information was obtained concerning the chemical mediators as well as the main cell types responsible for the establishment of inlammation and its relationships with the oral cavity. a cellular component. he vascular component represents changes in vessel diameter (vasodilation) and consequently increased blood low (causing redness and heat), and increased vascular permeability resulting in loss of plasma into the tissue and formation of luid exudate. he exudate contains many valuable proteins such as ibrin and immunoglobulin but it also gives rise to edema. he swelling distends the tissues; it may compress nerve endings and thus cause pain. According to its duration, inlammation is described as acute or chronic. Sometimes the acute process subsides but the stimulus persists suiciently to evoke a subsequent chronic inlammation. In other cases, with a stimulus that typically induces chronic inlammation, the tissues response may be acute in type for the irst day or so. Suice it to say at this stage that the tissue response difers considerably in acute and chronic. he cellular component involves the movement of white blood cells (leukocytes) from the blood vessels into the inlamed tissue. hey extra vasate from the capillaries into tissue, and act as phagocytes, picking up bacteria and cellular debris. hey may also aid by walling of an infection and preventing its spread. Inlux of neutrophils is one of the earliest stages of the inlammatory response. hese cells mount a rapid, non- speciic phagocytic response. Later, monocytes/macrophages and cells of other lymphocyte lineages (speciic subsets of T cells and B cells) appear at the site of injury; cell types which are associated with antigen-speciic and more tightly regulate immune responses and once activated also produce protective and inlammatory molecules. he lymphocytes are the primary cells of the immunologic system, and have developed one of the more sophisticated intelligent defense mechanisms in the biological system. he review of ALAM and GORSKA [2], enlightens that the T lymphocytes play a major role in the organization of the immune response, eliminating intracellular pathogens (virus, and bacteria) through the generation of cytotoxic T lymphocytes. he B lymphocytes protect the organism against extracellular pathogens by the production of antibodies. he Introduction he earliest known description of inlammation comes from the Edwin Smith Papyrus, one of the Egyptian papyri found in a tomb near hebes. he Papyrus dates from about 1550 B.C., but it is undoubtedly a copy of ancient tests of the archaic period of Egyptian history (3200-2780 B.C.) Documents from Egyptian and other early civilizations leave no doubt that the features of inlammation were recognized from very early periods; although the understanding of the process took a long time to happen. Inlammation can be considered as the irst response of a living tissue to injury and may be referred to as the innate immunity, and may appear due to microbial infections, physical factors (trauma, radiation, temperature), chemical substances (irritant and corrosive chemicals), as well as tissue necrosis and hypersensitivity reactions. It is didactically characterized by the following quintet: redness (rubor), heat (calor), swelling (tumor), pain (dolor) and dysfunction of the organs involved (functio laesa). he irst four characteristics were drawn up by Celsus nearly 2000 years ago; function laesa was added to the deinition of inlammation by Rudolf Virchow in 1858, considered the predecessor of modern pathology and social medicine. It was the latter who, in the ield of inlammation, critically analyzed the meaning of the four key symptoms (redness, swelling, heat and pain) and postulated that inlammation could not be represented as a single process but rather constituted of various inlammatory processes. Vascular and cellular considerations A deinition of inlammation is complicated, because the local vascular and tissue reactions oten are accompanied by systemic efects that include malaise, fever, leukocytosis, metabolic disturbances and shock. he process of inlammation can be deined as the succession of changes which occurs in the living tissue when it is injured, provided that the injury is not of such a degree as at once to destroy its structure and vitality [1]. he inlammatory response consists of a vascular and Review Article A Literature Review of Inlammation and Its Relationship with the Oral Cavity Luciano Silva* University of Pernambuco, Brazilian Association of Odontology, Brazil Dates: Received: 10 October, 2015; Accepted: 02 November, 2015; Published: 04 November, 2015 *Corresponding author: Luciano Silva, University of Pernambuco, Brazilian Association of Odontology - ABO – Recife, Tel: 55 81 30316824; E-mail: www.peertechz.com Keywords: Inlammation; Cytosine; Leukocytes
