Core Tip

Core tip: The average eradication rate of gastric Helicobacter pylori (H. pylori) has decreased in recent years. However, some foreign studies have shown that the eradication rate of gastric H. pylori may be improved by eliminating the presence of oral H. pylori rather than increasing the dose of antibiotics. In most studies, H. pylori DNA was detected and used to confirm oral H. pylori infection, and later determine whether professional periodontal treatments were effective in killing oral H. pylori. To avoid the expensive and complicated techniques involved with this approach, the current study used a cost-effective and simple method to test for and eliminate oral H. pylori. This method can be used to prove the elimination of gastric H. pylori, and is practical for use in the clinic.
