The presence of Helicobacter pylori in oral cavities of patients with leukoplakia and oral lichen planus.

Objective: Helicobacter pylori infection is one of the most common bacterial infections in men. This gastrointestinal pathogen is closely related to gastritis, peptic ulcers, and the increased risk of gastric cancer. Numerous studies have indicated oral cavities as possible Helicobacter pylori reservoirs.

Porphyromonas gingivalis in periodontal pockets and heart valves.

Background: There is evidence that advanced infectious chronic periodontal inflammatory disease may have an impact on general health including cardiovascular diseases. The aim of this clinical study was to evaluate the ability of Porphyromonas gingivalis to colonize heart valves and, subsequently, to assess whether there is an association between the presence of the DNA of Porphyromonas gingivalis in periodontal pockets and in degenerated heart valves.

Materials And Methods: Thirty patients were enrolled in the study and 31 valve specimens harvested during cardiac surgery operations were examined.

Role of PCR in Helicobacter pylori diagnostics and research--new approaches for study of coccoid and spiral forms of the bacteria.

Helicobacter pylori since Marshall and Warren's discovery has been an object of interest of gastroenterologists and many researchers of other specialties. What needs to be highlighted is also the growing interest of dentists in the role of oral residue of H. pylori in oral pathologies such as burning mouth syndrome, periodontitis and gingivitis.
