Summary

Anti-infective periodontal therapy, combining mechanical debridement with antibiotics or antiseptics, shows improved outcomes for advanced periodontal disease. Povidone-iodine and sodium hypochlorite offer broad-spectrum antimicrobial benefits with lower resistance risk.

Clinical and experimental dental research·2024

Area of Science:

  • Periodontology
  • Microbiology
  • Pharmacology

Background:

  • Interest in anti-infective periodontal therapy is growing, supported by research and commercial investment.
  • Effective management of periodontal microbiota is crucial for treating periodontal disease.

Observation:

  • Combining mechanical debridement with antibiotic drugs or antiseptic agents enhances treatment efficacy, particularly for advanced periodontal disease.
  • Systemic antibiotics like metronidazole with amoxicillin or ciprofloxacin are effective but can be challenged by yeasts and resistant bacteria.
  • Subgingival antiseptics such as povidone-iodine and sodium hypochlorite offer broad-spectrum antimicrobial action, reduced resistance risk, and lower costs compared to antibiotic devices.

Findings:

  • Mechanical debridement coupled with subgingival povidone-iodine and sodium hypochlorite irrigation is a valuable antimicrobial approach for most periodontal diseases.

  • Antiseptics demonstrate broader antimicrobial spectra and are less likely to induce bacterial resistance or adverse host reactions than antibiotics.
  • The selection of a chemotherapeutic regimen necessitates understanding microbial flora, available agents, and pathogen susceptibility.

    • Implications:

    • Povidone-iodine and sodium hypochlorite represent cost-effective and broadly applicable antimicrobial agents in periodontal care.
    • For moderate to severe periodontitis, adjunctive systemic antibiotics or surgical interventions may be necessary.
    • This approach supports the development of effective and sustainable strategies for managing periodontal infections.
