Background: The microorganism Helicobacter pylori has been closely linked to chronic gastritis, peptic ulcer, gastric cancer, and mucosa‐associated lymphoid tissue (MALT) lymphoma. Despite the current treatment regimens that lead to successful management of H. pylori‐positive chronic gastritis, the reinfection rate is high. It has been suggested that one of the possible mechanisms of reinfection is the recolonization from dental plaque. The purpose of this study was to determine whether dental plaque, poor oral hygiene, and periodontal disease were risk factors for H. pylori infection. Methods: Among the 134 patients, 65 patients who had a positive H. pylori serology or positive rapid urease test or histologic evidence for the presence of H. pylori in antral biopsy specimens were categorized as cases. The remaining 69 patients who were negative for H. pylori serology, the rapid urease test, and histology were controls. Results: It was found that the association of periodontal disease and poor oral hygiene with H. pylori infection was not significant. There was a higher prevalence of H. pylori in the dental plaque of patients with gastric H. pylori infection than in controls, but both groups had a surprisingly high positive urease test for H. pylori in plaque (89% and 71%, respectively). Conclusions: H. pylori in dental plaque is seldom eliminated by H. pylori‐eradication therapy, and this may act as a source for future reinfection. Hence, eradication of H. pylori from the dental plaque should be made an important part of comprehensive management of H. pylori‐associated gastric diseases.

“…The presence of H. pylori in dental plaque was examined by RUT and the results were expressed as either positive or negative. Studies have reported specificity of this test of nearly 100%, and sensitivity between 70% and 90% . The prevalence of H. pylori colonization in dental plaque in the present population studied was found to be 54%.…”

This randomized controlled study evaluated the association of Helicobacter pylori (H. pylori) with chronic periodontitis patients with and without type II Diabetes Mellitus. H. pylori is considered to be a pathogen responsible for gastritis, peptic ulcers and a risk factor for gastric cancer. The aim of the present study was to evaluate the association of H. pylori with chronic periodontitis patients with and without type II diabetes mellitus before and after treatment. The prevalence of H. pylori in periodontal pockets was determined by rapid urease test in a 36 patients, which were grouped as Group 1 (Healthy subjects), Group II (chronic periodontitis patients) and Group III (Chronic periodontitis patients with Type II Diabetes Mellitus), 12 in each group before treatment by collecting plaque samples. After treatment, 12 plaque samples were collected and prevalence H. pylori was detected. Group II and Group III had a significantly higher rate of positive results for H. pylori compared to healthy subjects before treatment. After treatment, H. pylori were not detected in Group II and in Group III Only one of 12 chronic periodontitis patients with Type II diabetes mellitus had H. pylori in the periodontal pocket. The prevalence of H. pylori did not differ significantly between the chronic periodontitis patients with and without type II diabetes mellitus. Meticulous scaling and root planning will reduce the prevalence of H. pylori in periodontal pockets.
