Helicobacter pylori is Gram negative spiral bacterium, who lives in microaerophilic conditions. The infection with this bacterium is mostly acquired in childhood and the improvement of the hygiene practices in older ages leads to decreasing the level of infection. Humans are the main reservoir. This bacterium is transmitted by oral – oral route or fecal – oral route. Inadequate supplement with microbiological clean water, disposition of the fecal and other waste products are the risk factors for infection with Helicobacter pylori. It colonizes the stomach mucosa and causes different diseases as chronic gastritis, stomach and duodenal ulcers, gastric adenocarcinoma and gastric lymphoma. Also this bacterium colonizes the oral cavity and that is why it’s isolated from the dorsum of the tongue and dental plaque. Other places where it can be find is bucal mucosa, oral epithelium and tonsils. There are two possible ways how this microorganism comes in the oral cavity, the first way is by colonizing the oral cavity, the second way is by the reflux of the stomach acid, it comes here and stays in the oral cavity. The presence of H. pylori in the oral cavity results in oral lesions such as periodontal disease, recurrent aphthous stomatitis and halitosis. Early diagnosis is very important for starting the therapy for both conditions oral and gastric infection. The therapy may protect later disorders which can happen because of the persistence of the bacterium. The infection in the mouth is the main source for bacteria in the stomach, therefore, even the bacteria are eliminated from the gastric mucosa, the persistence in the dental plague, tongue results in reinfection. The oral lesions where is H. pylori most detected usually are ulcerative or inflammatory. As is mentioned in the beginning, this is microaerophilic bacterium, so the subgingival plaques are the ideal conditions for growth and existing. Because of the ideal conditions for living H. pylori exists here and causes periodontal disease in association with the dental plaque, including chronic periodontitis. When there is greater plaque index, if it was present before, there is higher risk to be present H. pylori and this two factors may lead to increasing the level of inflammation such as periodontitis. The persistence of H. pylori in subgingival dental plaque can lead to constant reinfection and failure in eradication therapy. This microorganism is possible reason for oral malignant diseases because it is proved that can cause malignancies in the stomach such as adenocarcinoma and MALT lymphoma. The persistence of H. pylori in the mouth is risk factor for dentists to acquire this infection during regular working. They can acquire this infection, or can transmit to their patients, so using glovers, washing hands must be done after finishing work with every patient, to prevent H. pylori to be transmitted by the dentists. Keywords: infection, risks, diseases, mouth, stomach.
