It is difficult to eradicate Helicobacter pylori from dental plaque by triple therapy.

Abstract

The high coexisting infection rate of H. pylori in both stomach and dental plaque implies that dental plaque can serve as another reservoir of H. pylori. H. pylori in dental plaque was hardly eradicated by triple therapy. Dental plaque may be a potential source for recrudescence of gastric infection after successful systemic therapy.
