Background and Aims: Helicobacter pylori (H. pylori) is a gram-negative, microaerophilic, spiral-shaped flagellated bacterium that is urease, catalase and oxidase positive. One of its pathogenicity factors is the iceA gene. H. pylori has recently been recognized as a genetic indicator for the development and evolution of duodenal ulcer disease in the East. This study aimed to determine the presence of this bacterium in gingival plaques in non-endocrine patients in Bojnourd city, and the polymerase chain reaction technique examined the percentage of iceA gene.
Materials and Methods: A total of 100 samples of dental plaque were taken and transferred to a tube that has been physiologically placed. After DNA extraction, primer design was performed, and then the polymerase chain reaction was performed for the whole sample.
Results: Of 100 samples examined in this study, two samples of H. pylori were positive (2%), and the frequency of the iceA gene of two samples was positive (100%).
Conclusion: In the Bojnord city, the frequency of iceA gene in people is high, and the frequency of H. pylori in tooth plaques is low. Also, iceA gene can be considered as an indicator for predicting the contamination and risk of H. pylori infection in the region. To confirm the results, more molecular studies are required in other populations.
