The aims of the study were to assess (1) the association between gastric and oral <jats:italic>H.\u00a0pylori<\/jats:italic> colonization and (2) the association between oral colonization of <jats:italic>H.\u00a0pylori<\/jats:italic> and dental diseases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross\u2010sectional study was conducted in King Fahad University hospital in Khobar, Eastern Saudi Arabia in 2017. Patients admitted to the Endoscopy Unit were recruited and clinically examined for plaque, decayed teeth (D), filled teeth (F), missing teeth (M), periodontal pocket depth (PPD), attachment loss (AL), and gingival bleeding in addition to assessing their age, gender, education, tooth brushing, flossing, and tobacco use with a questionnaire. Pooled dental plaque samples were collected and analyzed using nested polymerase chain reaction PCR to detect oral <jats:italic>H.\u00a0pylori<\/jats:italic>. Gastroscopy was used to extract biopsies to assess gastritis and the presence of gastric <jats:italic>H.\u00a0pylori<\/jats:italic> using Giemsa stain. Regression analysis was used to assess differences between patients with and without gastritis, oral H. pylori and gastric H. pylori in the percentage of sites with gingival bleeding, PPD, CAL, D, M, and F with adjustment for confounders.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred twenty patients were included.

No significant association was observed between the percentage of sites with gingival bleeding, mean PPD, AL, F, and either gastritis, the presence of oral or gastric <jats:italic>H.\u00a0pylori<\/jats:italic>.
