Overview

Cross-sectional study analyzes microbial profiles in peri-implantitis and healthy teeth, indicating implications for treatment.

Key Points

  • The study aims to analyze microbial profiles at peri-implant sites compared to adjacent teeth and examine factors affecting these profiles.
  • Cross-sectional study involving 43 adults with 100 dental implants and 50 adjacent teeth.
  • Samples collected using sterile paper points and analyzed via quantitative PCR for 22 bacterial taxa.
  • Subgroup analyses performed based on smoking and periodontal health.
  • Peri-implantitis sites exhibited significantly greater bacterial loads for 10 taxa compared to adjacent teeth.
  • Key taxa included Campylobacter rectus and Porphyromonas gingivalis, showing high detection frequencies in peri-implantitis.
  • Clinically, higher proportions of bleeding and suppuration were present at peri-implantitis sites than healthy implant sites.
