title: Molecular detection and corelation of Helicobacter pylori in dental plaque and gastric biopsies of dyspeptic patients.
abstract: Helicobacter pylori is a microaerophilic organism, which colonizes in the gastric mucosa. Its role in etiology and development of acute and chronic gastritis and peptic ulcer diseases is scientifically proved. Oral cavity especially supragingival, subgingival plaque and so forth simulate the same microaerophilic environment favorable for the growth of this bacterium.
  
  
  OBJECTIVE
  Detection of H. pylori simultaneously in the oral cavity and gastric mucosa of patients suffering from gastric pathologies.
  
  
  OBJECTIVE
  To detect H. pylori in the oral cavity and gastric mucosa using endoscopy, urease test and real-time polymerase chain reaction (PCR) (urease A gene). Determining its association and corelation with patient demographics, oral hygiene maintenance and periodontal disease status.
  
  
  METHODS
  Endoscopic examination, oral findings oral hygiene index-simplified (OHI-S) and community periodontal index and treatment needs (CPITN) indices were recorded. Antral biopsies and supragingival plaque samples were taken from 56 dyspeptic adult patients. The collected samples were subjected to histological examination, urease broth test and urease A gene amplification using real-time PCR.
  
  
  RESULTS
  H. pylori was detected in the supragingival plaque of individuals with H. pylori-induced gastric diseases using rapid urease test and real-time PCR analysis. Occurrence of same strain of H. pylori simultaneously in plaque and gastric mucosa was observed. Positive correlation was obtained between the collected indices and quantity of H. pylori colonization.
