Helicobacter pylori (H. pylori) is a gram-negative bacterium predominantly known for colonizing the gastric mucosa, leading to conditions such as chronic gastritis, peptic ulcers, and an increased risk of gastric cancer.

Beyond its gastric implications, emerging evidence suggests that the oral cavity, particularly dental plaque, may serve as a significant reservoir for H. pylori, influencing both its transmission and recurrence.
Presence of H. pylori in the Oral Cavity
Recent studies have detected H. pylori in various oral sites, including dental plaque, saliva, and dental pulp.
A meta-analysis encompassing 23 studies with 1,861 patients found that the rate of co-infection with H. pylori in both gastric tissues and dental plaque was approximately 49.7%.
This significant prevalence underscores the potential role of the oral cavity as a reservoir for the bacterium.
Association with Periodontal Diseases
The relationship between H. pylori and periodontal diseases has been a focal point of recent research.
Some studies suggest that dental plaque and saliva could harbor H. pylori, potentially leading to gastric infections or re-infections post-eradication.
However, the evidence remains inconclusive, with some studies indicating a significant association between periodontal disease and gastric H. pylori infection, while others do not.
Implications for Transmission and Recurrence
The detection of H. pylori in dental plaque and saliva indicates that the oral-oral route could be a plausible mode of transmission.
Moreover, the oral cavity might act as a persistent source of the bacterium, potentially leading to re-infection of the gastric mucosa after systemic eradication therapy.
This possibility highlights the importance of considering oral health in managing H. pylori infections.
Therapeutic Considerations
Given the potential role of the oral cavity in harboring H. pylori, integrating periodontal therapy with standard eradication regimens has been proposed.
A systematic review suggested that periodontal therapy, including mechanical debridement and improved oral hygiene practices, may serve as an adjunctive treatment, potentially enhancing eradication rates and reducing recurrence.
However, further large-scale studies are necessary to confirm these findings.
Conclusion
The oral cavity, particularly dental plaque, may play a significant role in the transmission and recurrence of H. pylori infections.
While evidence supporting this association is growing, further research is essential to elucidate the mechanisms involved and to develop comprehensive treatment strategies that address both gastric and oral reservoirs of the bacterium.
Emphasizing oral hygiene and considering periodontal therapy could become integral components in the effective management of H. pylori-related diseases.
Annual Control Plan for Patients to Minimize the Presence of Helicobacter pylori in Dental Plaque
To reduce the risk of Helicobacter pylori colonization in the oral cavity and minimize its transmission and recurrence, dental professionals worldwide should implement a structured annual control plan.
This plan consists of regular dental check-ups, professional plaque removal, and patient education on optimal oral hygiene practices.
Annual Control Plan
1. Initial Evaluation and Personalized Risk Assessment (Month 1)
- Comprehensive oral examination to assess dental plaque accumulation, periodontal health, and signs of H. pylori-related conditions.
- If necessary, conduct microbial tests to detect H. pylori in the oral cavity.
- Develop a personalized prevention and treatment plan.
2. Professional Plaque Removal and Hygiene Reinforcement (Every 3-4 Months)
- Schedule professional dental cleanings every 3 to 4 months to eliminate plaque and bacterial biofilm, reducing potential H. pylori reservoirs.
- Provide periodontal therapy if needed (scaling, root planing, or antimicrobial treatments).
- Reinforce proper oral hygiene techniques, including brushing, flossing, and the use of antimicrobial mouthwashes.
3. Patient Education and Home Care Monitoring
- Educate patients on the possible link between H. pylori and oral health, emphasizing the importance of oral hygiene in preventing infections.
- Recommend the use of antibacterial toothpaste and mouthwash with chlorhexidine or other antimicrobial agents.
- Advise on dietary modifications to reduce plaque accumulation and promote oral health (e.g., reducing sugar intake and increasing probiotic consumption).
4. Follow-up and Reassessment (Month 12)
- Conduct an annual reassessment to monitor oral health progress and evaluate any signs of H. pylori reinfection.
- If needed, perform additional microbial testing to ensure H. pylori eradication from the oral cavity.
- Adjust the treatment and prevention plan based on individual patient needs.
This structured approach helps maintain optimal oral health, prevents plaque accumulation, and reduces the potential for H. pylori transmission and reinfection.
