The actual importance of the oral cavity in Helicobacter pylori human infection has caused much controversy. Several articles in specialized literature with antagonic results have seen found. To investigate Helicobacter pylori in oral cavity, samples of subgengival biofilm were collected of 40 dyspeptic patients and underwent to immunocitochemistry and citopatological study by Papanicolaou and Giemsa methods. In addition, Helicobacter pylori was investigated in the stomach by endoscopy. Gastric samples were taken for the urease test, histopathological, immuno - histochemistry and immunocitochemistry examinations. A total of 40 subjects examined, 35 (87,5%) were immunopositive for Helicobacter pylori in dental biofilms, 33 (82,5%) were considered gastric carriers of Helicobacter pylori and 30 (75%) were positive for Helicobacter pylori in both sites. The results showed that the oral cavity, like by the stomach, is an important reservoir of Helicobacter pylori, what make the oral-oral route of Helicobacter pylori transmition stronger in adults. We also concluded that the prevalence of Helicobacter pylori in oral cavity is not dependent on the periodontal status, given that of the 14 subjects without periodontal disease, 13 (93%) were immunoreactive for Helicobacter pylori. Morever, periodontitis doesn t seem to interfere with Helicobacter pylori gastric infection.
