Effect of Dental Plaque Control on Infection of Helicobacter pylori in Gastric Mucosa

Abstract

Long-term professional dental plaque control was associated with less gastric reinfection by H. pylori, suggesting that dental plaque control may help to prevent H. pylori-induced gastric disease or reinfection.

Oral Cavity and Systemic Diseases—Helicobacter Pyloriand Dentistry

“…77.3% of the patients treated with combined periodontal therapy exhibited successful eradication of gastric H. pylori, compared with 47.6% who underwent only triple therapy (26). Similar results were obtained by Jia et al (15). long-term professional dental plaque control was associated with less gastric reinfection by H. pylori, suggesting that dental plaque control may help preventing H. pylori-induced gastric disease or reinfection.…”

An evaluation of selected oral health indicators and cariogenic bacteria titer in patients with Helicobacter pylori

“…Other species of bacteria that secrete urease in the plaque, such as Streptococci, Actinomyces or Haemophilus spp, can cause false positives. 18,19 The research team of Silva et al demonstrated a correlation between the colonization of supragingival plaque and oral health parameters -specifically, between the percentage of the surface covered with dental plaque and the bleeding rates of periodontal pockets. 16 Patients with higher values of these 2 indicators were likely to report the presence of H. pylori in their oral cavities.…”

“…Jia et al emphasize the importance of dental plaque as a temporary reservoir of bacteria and show that long-term professional management reduces re-infection of the stomach following eradication treatment. 19,20 The failure of triple eradication therapy for treating H. pylori in the oral cavity is a consequence of a failure to achieve an effective concentration of antibiotics in the saliva and dental plaque. 19 12 In patients with appropriate oral hygiene, low or even no trace amounts of H. pylori bacteria may be present in the oral cavity.…”

“…19,20 The failure of triple eradication therapy for treating H. pylori in the oral cavity is a consequence of a failure to achieve an effective concentration of antibiotics in the saliva and dental plaque. 19 12 In patients with appropriate oral hygiene, low or even no trace amounts of H. pylori bacteria may be present in the oral cavity. This is explained by the fact that the the bacterium is driven out by early colonizers of the oral cavity.…”

The Emerging Concepts on the Impact of Periodontitis on Systemic Health

“…However, studies conducted in this regard have shown encouraging results. Recently it was reported that plaque control results in lesser prevalence of H. pylori in the gastric mucosa (Jia et al, 2009). Another study reported that 77.3% of the patients treated using a combination of periodontal treatment and triple therapy exhibited successful eradication of gastric H. pylori, compared with 47.6% who underwent only triple therapy (Zaric et al, 2009).…”
