title: Helicobacter pylori in dental plaque and gastric mucosa: correlation revisited.
abstract: Helicobacter pylori (H. pylori) related gastric infection is highly prevalent in developing countries. Prevalence of bacterium in dental plaque from these regions is also reported to be high, but association between simultaneous colonization of H. pylori in both these sites has not been established yet. Aim of this paper is to review possible association between simultaneous oral and gastric H. pylori colonization in dyspeptic patients. Pertinent literature was reviewed and all available evidence collected from Medline and PakMedinet. Studies conducted in the developing world show conflicting results. Some report a positive relation between oral and gastric H. pylori colonization while others deny any association. This may be due to the population sampled or methodology applied. Further studies are recommended to confirm the association between concurrent presence of H. pylori in dental plaque and gastric mucosa of dyspeptic patients using sensitive and specific tests for detection of bacterium in oral samples.
