Abstract

Background & Aim: HELICOBACTER PYLORI is a major cause of gastric ulcer and PEPTIC ULCER and isconsidered a risk factor for gastric cancer. Gingival grooves in the teeth of people with chronicperiodontitis may act as a reservoir for H. pylori. Therefore, the aim of this study was to investigate thevirulence genes of H. pylori isolated from DENTAL PLAQUEs. Material & Methods: The study was cross--sectional and from 120 patients with periodontitis referringto Tehran dental clinics, 111 DENTAL PLAQUE samples were isolated. Sterile physiology serum was used totransfer the sample. Growth in Brucella agar + 1% starch + 10-7% at 37 ° C and 95% humidity and CO2concentration of 0. 5% in CO2 incubator. In order to identify the molecules, DNA extraction wasperformed and then the sequences of JW22 and JW23 regions were used for accurate identification. Results: Of the 111 DENTAL PLAQUE samples taken from 120 participants in this study, 22 strains (19%)were positive for H. pylori which 10 strains carrying different H. pylori virulence genes. The molecularanalysis of the studied genes showed that the frequency of cagA, cagT, cagE, vacA and hrgA genesshowed that the prevalence of these genes was 19% of H. pylori strains of 3 (57. 5%), 1 (0. 19%), %), 2(0. 34%), 1 (19. 1%) and 1 (0. 19%), respectively. Conclusions: It seems that in spite of the presence of HELICOBACTER PYLORI virulence genes in the dentalplaque, to control the related diseases in addition to antibiotic treatments periodontal treatments anddental plaque control are also required.
