Article Synopsis
  • Endodontic infections include issues like pulp necrosis and abscesses, where identifying harmful bacteria like Enterococcus faecalis and others is crucial for proper diagnosis and treatment.
  • A systematic review analyzed the prevalence of these bacteria using the Checkerboard DNA-DNA hybridization technique across 17 studies, evaluating 620 samples, finding high prevalence rates (74% for E. faecalis, 63% for P. gingivalis, etc.).
  • The presence of these bacteria can hamper endodontic therapy effectiveness and is often linked to recurring infections, making DNA-DNA hybridization a valuable and efficient tool for tailored endodontic treatments.
