Detection of <i>Helicobacter pylori</i> by Polymerase Chain Reaction in the Subgingival Biofilm and Saliva of Non‐Dyspeptic Periodontal Patients

Abstract excerpt

BACKGROUND: Helicobacter pylori has been associated with the development of peptic ulcers and gastric cancer. Although the oral cavity may be a source of transmission, it is unknown whether it acts as a permanent reservoir for this bacterium, particularly in the presence of periodontal disease. The purpose of this study was to evaluate the prevalence of H. pylori by polymerase chain reaction (PCR) in the...
