Helicobacter pylori in dental plaque
Journal of Clinical Gastroenterology
|September 1, 1995
Summary
Helicobacter pylori (H. pylori) can reside in dental plaque, acting as a reservoir for reinfection even after stomach treatment. Eradicating H. pylori from dental plaque remains a significant challenge for permanent cure.
Area of Science:
- Microbiology
- Gastroenterology
- Oral Health
Background:
- Helicobacter pylori (H. pylori) was traditionally considered confined to the gastric and duodenal mucosa.
- Recent findings identify H. pylori in human dental plaque (DP), challenging previous understanding of its reservoirs.
- Prevalence varies globally, being more common in developing countries.
Discussion:
- Failure of standard triple therapy to eradicate H. pylori from DP, while successful in the gastric mucosa, suggests DP as a potential reservoir.
- This raises concerns about H. pylori reinfection of the gastric mucosa from the oral cavity.
- Permanent cure of duodenal ulcers may necessitate eradication from both gastric and dental plaque sites.
Key Insights:
- Dental plaque is identified as a significant reservoir for Helicobacter pylori.
- H. pylori in dental plaque may contribute to treatment failure and reinfection of the gastric mucosa.
- Current therapeutic strategies are ineffective for eradicating H. pylori from dental plaque.
Outlook:
- Further research is needed to develop effective strategies for H. pylori eradication from dental plaque.
- Investigating the role of dental plaque in H. pylori epidemiology and treatment outcomes is crucial.
- Novel approaches targeting oral reservoirs are essential for achieving sustained H. pylori clearance.

01:16Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy
Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...
01:30Peptic Ulcer Disease I: Introduction
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

01:27The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
01:27Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
01:24Peptic Ulcer Disease II: Pathophysiology
Peptic ulcer disease develops when protective mechanisms of the gastrointestinal mucosa are overwhelmed by harmful factors, leading to localized erosions in the stomach or proximal duodenum. The main causes are Helicobacter pylori infection and chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs).Helicobacter pylori–Induced InjuryBacterial Adaptation and Colonization:H. pylori is a spiral, Gram-negative bacterium adapted to the acidic stomach. and transmitted through oral-oral or...
