PATHOGENIC MECHANISMS OF GENERALIZED PERIODONTITIS FROM THE POSITION OF POLYMORPHISM OF NUCLEAR TRANSCRIPTION FACTOR NF- κВ1

Background. Periodontal diseases are a topical issue of contemporary dentistry because they are accompanied by severe morphological and functional disorders of maxillodental system; and are characterized by polyetiology and a number of metabolic disorders.The purpose of this study was to substantiate the pathogenic mechanisms of generalized periodontitis in relation to polymorphism of nuclear transcription factor NF- κB1.Objective. The aim of the study was to determine the genetic factors in the development of generalized periodontitis and the relationship of this parameter with immunohistochemical affiliation for cellular infiltrate of the lamina propria of gum at this nosology in young people. Hence, 2 groups were formed: І – control and II – observational.Methods. Polymorphic gene section NF-κB1 was determined using the cells of buccal epithelium of the examined people by means of polymerase chain reaction. Collection of material was performed with sterile disposable dental brush, followed by the introduction of a reagent in ependorph with DNA Express reagent (LyTeh NPF, Russia). Genome deoxyribonucleic acid was isolated by DNA Express set (LyTeh, Moscow).Results. The lack of correlation in this case indicates that no matter how parameters change, relatively major genotype (Del/Del) in this case is unchanged and the determining factor causes the development of generalized periodontitis, clinical picture of which is rapidly progressing.Conclusions. Results of correlation analysis proved that genotype (Del/Del), as polymorphic variant of gene transcription factor NF-κB1, was significantly associated with the emergence of rapidly progressive periodontitis in young people
