Oral Helicobacter pylori: can we stomach it?
1Indiana University School of Dentistry, Department of Periodontics and Allied Dental Programs, 1121 West Michigan Street, Indianapolis, IN 46202, USA.
Summary
Helicobacter pylori (H. pylori) may spread through the oral cavity, acting as a reservoir for the stomach bacterium. Understanding oral transmission is key to preventing gastric disease spread.
Area of Science:
- Microbiology
- Gastroenterology
- Oral Medicine
Background:
- Helicobacter pylori infection is a prevalent global health issue.
- H. pylori resides in the stomach, causing significant gastric diseases.
- Preventing H. pylori spread necessitates understanding its transmission routes.
Purpose of the Study:
- To review evidence supporting the oral cavity as a reservoir for gastric H. pylori.
- To discuss challenges and future research directions in H. pylori oral transmission.
- To explore implications for dental professionals regarding H. pylori.
Main Methods:
- Literature review of studies detecting H. pylori in oral samples.
- Analysis of culture and PCR detection methods for H. pylori in saliva and dental plaque.
- Synthesis of evidence regarding the oral-to-gastric transmission hypothesis.
Main Results:
- H. pylori has been detected in human dental plaque and saliva using culture and PCR.
- The oral cavity is a potential reservoir facilitating H. pylori transmission.
- Evidence suggests a role for oral hygiene in managing H. pylori.
Conclusions:
- The oral cavity plays a potential role in the transmission of gastric H. pylori.
- Further research is needed to clarify the exact mechanisms and significance of oral H. pylori.
- Dental professionals should be aware of H. pylori oral carriage and its implications.
