Endodontics · single question

What is the typical bacterial profile of an endodontic (periapical/dental) abscess?

  1. One to two aerobic species
  2. One to two anaerobic species
  3. More than three aerobic species
  4. Polymicrobial, more than three predominantly anaerobic species
Show answer and explanation

Correct answer: D. Polymicrobial, more than three predominantly anaerobic species

Endodontic abscesses are polymicrobial and predominantly anaerobic, typically involving multiple (often more than three) species.Other options: Aerobe-only or one-to-two-species descriptions understate the polymicrobial, anaerobe-dominant nature of these infections.Key exam takeaway: Endodontic/periapical abscesses are polymicrobial and mainly anaerobic.
