Bacteria were quantified by real-time polymerase chain reaction with TaqMan MGB probes. Six different IL-18 gene polymorphism (-656, -607, -137, +113, +127, and codon 35/3) were studied and none of the polymorphisms were associated with destructive periodontal disease. Reports of genetic polymorphisms associated with periodontal disease are increasing, but the limitations of such studies are not widely appreciated. Genetic polymorphisms of several cytokines have been previously reported in the pathogenesis of chronic and aggressive periodontitis , , . Periodontitis, a chronic inflammatory disease, caused by gram-negative microorganisms in the periodontal pockets, is no exception. Material and Methods: A comprehensive literature search was performed. genetic polymorphisms in periodontal diseases. Genetic polymorphisms in the interleukin-4 (IL4) gene have been reported to influence the host response to microbial challenge by altering levels of cytokine expression.We analyzed nucleotide polymorphisms in the promoter region of the IL4 gene and its relation with periodontal disease in a Macedonian population. FcγRIII receptors Periodontitis is a bacterial inflammatory disease leading to attachment loss with the consequence of tooth loss. Gene polymorphisms were determined by multiplex SNaPshot technique. Family studies suggest that susceptibility to the early onset forms of disease, particularly prepubertal and juvenile periodontitis, is, at least in part, influenced by host genotype. SNPStats and SPSS 18.0 were used for the analysis of genetic data and logistic regression models were utilized … 3. Introduction. T. H. Harris. More than any other cytokine family, the interleukin (IL)–1 family includes key signaling molecules that trigger and perpetuate periodontal inflammation. Periodontal disease is an inflammatory illness that represents the main cause of tooth loss in developed countries, with increasing prevalence in the developing world[1]. GENETICS – AN INSIGHT Genetics is the study of inheritance or heredity of living things. In fact, genome-wide studies and screening of single-nucleotide polymorphisms have yielded new genetic information without a definitive solution for the management of periodontal disease. Keywords: Periodontal disease, Single nucleotide polymorphisms, Interleukin-1, Genetic factors, Oral Microbiology. Recent studies suggest that polymorphisms of the (IL-1) gene complex may be significant risk factors for a number of chronic inflammatory diseases. Single nucleotide polymorphisms (SNPs) present in a plurality of genes were examined for association with periodontitis disease. [ 20 ] Periodontal Disease, Gene Polymorphisms, Chronic Periodontitis, Aggressive Periodontitis, Hereditary Gingival Fibromatosis . The severity of periodontal disease has been positively associated with carriage of allele 2 at position -889 of the IL-1A gene in conjunction with allele 2 of the 1L-1B gene at position +3953. We retrieved a total of 53 studies summarizing information about 4178 cases and 4590 controls. … 2013 Oct;78(4):371-7. doi: 10.1111/sji.12095. 2. P. F. Gonçalves. Search for more papers by this author. J Clin Periodontol 2008; doi: 10.1111/j.1600-051X. 2008.01298.x. Over the years, the IL-1 family … Many studies have provided a valuable contribution to understanding the genetic basis of periodontal disease, but the specific candidate genes of susceptibility are still unknown. This initial study has since spawned numerous publications and has been the most influential in creating interest in gene polymorphisms and periodontal disease. T he purpose of this paper is to review current knowledge of genetic risk factors for the periodontal diseases and to present updated and additional data from the Minnesota Twin Periodontal Study. It is a wide ranging science that explores the transmission of biological properties from parent to offspring. The pioneer of genetics was Gregor Mendel (1822-1884). Genetics and Molecular Research 14 4: 1806918077 2015 FUNPECRP www.funpecrp.com.br formed by rs4647602 and rs113420705 were found to be associated with chronic this disease (TC haplotype, P = 0.0039; GT haplotype, P = 0.002). Reports of genetic polymorphisms associated with periodontal disease are increasing, but the limitations of such studies are not widely appreciated. Various gene polymorphisms which have been investigated for their role in periodontal disease. Bi-allelic polymorphism in the FcγRIIIb: In neutrophils, FcγRIIIb exists in two allelic forms, NA1, and NA2. Introduction . To investigate whether such polymorphisms might be involved in the development of periodontal disease, 51 patients and 33 control subjects were assessed. Taking into account age, gender and periodontal status, IL-10-592 AA, -819 TT and ATA/ATA genotype occurred more frequently in patients with CP than in healthy controls. This polymorphism is a result of nucleotide substitutions resulting in changes in four amino acids, which consequently results in differences in glycosylation. The article, which is a nonsystematic review of literature, will focus on the role of genetic polymorphisms in periodontal diseases. Single nucleotide polymorphisms in periodontal disease In general a person’s genetic background influences their susceptibility to many kinds of diseases and conditions. Gene polymorphisms in periodontal health and disease Gene polymorphisms in periodontal health and disease Takashiba, Shogo; Naruishi, Koji 2006-02-01 00:00:00 Gene polymorphisms are locations within the genome that vary in sequence between individuals and are very prevalent, affecting at least 1% of the population (104). Genetics - An Insight : Genetics is the study of inheritance or heredity of living things. J Int Clin Dent Res Organ 2017;9: 53-8. Proportion of smokers among subjects of increasing extent of periodontal disease as shown by quintiles according to Fig. Research into specific genetic polymorphisms is hampered by the fact that genetic variants, which are associated with periodontitis in, for example, Caucasians, may not be associated with disease in other ethnic populations such as Asians, Brazilians, and Africans. Necrotizing periodontal disease usually occurs in people who have suppressed immune systems, due to cancer treatments, HIV infections or malnutrition. The aim of this study was to determine whether chronic periodontal disease in a Brazilian population is associated with polymorphisms in the VDR gene. Periodontitis diseases can be examined by using SNPs and haplotypes in each gene region as indices. To investigate whether such polymorphisms might be involved in the development of periodontal disease, 51 patients and 33 control subjects were assessed. Genetics, periodontal diseases, polymorphisms, periodontitis risk factors. Necrotizing periodontal disease: This results from a lack of blood supply, which causes the death of the gum tissue supporting bone and tooth ligaments. Periodontal disease: a genetic perspective 34 Braz Oral Res., (São Paulo) 2012;26(Spec Iss 1):32-8 different types of polymorphisms are typically re-ferred to by the type of mutation that created them. Discipline of periodontology shifted the understanding of periodontal disease pathogenesis from solely microbial dental plaque based axis to complex, multi-variate interplay between infection and host response. Cytokines are regulatory low-weight proteins acting as mediators into genesis and control of immune and inflammatory response. Candidates for such genetic susceptibility factors are polymorphisms of genes modulating the immune response (e.g. What Causes Periodontal Disease? Department of Dentistry, Federal University of Jequitinhonha and Mucuri Valleys, Diamantina, MG, Brazil. systemic diseases and periodontal disease have been highlighted by the American dental association in 2006 [1], such as chronic obstructive pulmonary diseases [2], head and neck cancer [3], cardiovascular diseases [4], diabetes [5]. THE ROLE OF GENETIC POLYMORPHISMS IN PERIODONTAL DISEASES . Environmental-gene interactions may play some role in the risk of the disease. Therefore, seek the risk factor of periodontal disease and prevent them is an important and interesting work for overall health. Periodontal diseases are multifactorial diseases in which genetic and environmental factors affect the clinical outcome of the disease. Although the correlation between tobacco use and periodontal disease is quite strong, the role of tobacco in the pathogenesis of periodontal disease is uncertain. 1.
