Alagl AS, et al. - In King Fahad University hospital in Khobar, Eastern Saudi Arabia in 2017, researchers assessed 120 candidates to estimate the independent relationship between gastric and oral Helicobacter pylori (H. pylori) colonization and dental diseases. They noted 34.2% of individuals with gastric H. pylori and 5% with oral H. pylori. They found no significant correlation between the percentage of sites with gingival bleeding, mean periodontal pocket depth, attachment loss, filled teeth, and either gastritis, the presence of oral or gastric H. pylori. They concluded that the presence of gastric and oral H. pylori in cases with good oral hygiene and moderate socioeconomic status was not significantly related to periodontal diseases. A higher number of decayed and missing teeth was seen in patients with gastritis vs those without.
