Are the view of Helicobacter pylori colonized in the oral cavity an illusion?

Urea breath test (UBT), as a leading preferred non-invasive diagnostic technology, but may not be able to detect oral H. pylori . With negative results of UBT, the patient may have an oral infection. On the basis of the fact of success, eradication rate may increase by 21% in the 95% Cl range after the elimination of oral H. pylori, the author believes oral H. pylori does exist and the oral cavity is the second colonized site aside its primary site of the stomach. H. pylori migrated out of Africa along with its human host circa 60 000 years ago; they are not lives in stomach only. In this review article, evidence established in recent years studies with use more appropriate technology had been listed and discussed. The author considers the oral cavity is a black hole for H. pylori infection that significant effective on gastroenterology and another medical field. The role of the oral cavity as the source of H. pylori infection is so controvert in past years. It seems like a human being having a second-time face to discover H. pylori in the history. Gastric disease: Helicobacter pylori in the mouth H. pylori infection in the mouth could prevent eradication of the infection in the stomach and explain its high recurrence rate. In most cases, infection with the bacterium H. pylori is harmless, but many infected individuals develop stomach ulcers or gastric cancer. In a recent review John Yee of the Research Lab of Oral H. pylori , Everett, USA, argues that oral H. pylori needs to be tackled to clear the bacteria in the stomach. A new H. pylori saliva test is aiding the detection of oral infection and several studies have found a strong association between oral and stomach infection. Yee proposes concomitantly treating the oral infection through professional plaque removal and oral hygiene procedures, and treating the gastric infection with antibiotics. Increasing awareness of oral H. pylori infection could help prevent oral transmission.
