Bacterial Profile Associated with Peri-Implantitis: A Systematic Review

Area of Science:

• Microbiology
• Periodontology
• Biomaterials Science

Background:

• Peri-implant sulci harbor distinct microbial communities.
• Understanding these differences is crucial for diagnosing and managing peri-implantitis.
• Current literature lacks a consolidated comparison of microbial profiles in healthy versus diseased peri-implant sites.

Approach:

• Systematic review of existing literature.
• Comprehensive search of PubMed, Google Scholar, and Cochrane databases.
• Inclusion of ten studies comparing microbial profiles of healthy and failing implants.

Key Points:

• Significant variations in microbial profiles exist between healthy and diseased peri-implant sulci.
• Gram-negative anaerobic organisms predominate in both conditions but differ in abundance and species.
• Specific red complex bacteria (P. gingivalis, T. forsythia, P. intermedia) are prevalent in diseased peri-implant sites.
• Obligate anaerobic Gram-negative bacteria, including T. denticola, are characteristic of peri-implantitis.

Conclusions:

• Peri-implantitis is associated with a distinct and diverse microbial community.
• Identifying specific bacterial flora in diseased sites can guide targeted treatment strategies.
• Further research into peri-implantitis-associated bacteria is warranted for improved therapeutic interventions.
