Which bacteria are most commonly associated with pericoronitis?

• A. Gram positive cocci
• B. Gram negative, rods, obligate anaerobes
• C. Gram positive rods
• D. Gram negative, cocci, facultative anaerobes

Answer: (B)

Pericoronitis is an inflammation of the soft tissues surrounding a partially erupted tooth, most commonly the third molars (wisdom teeth). The primary bacteria involved in pericoronitis are typically Gram-negative, rod-shaped, obligate anaerobes. In the context of pericoronitis, these bacteria thrive in the anaerobic environment found in the oral cavity, particularly under conditions where there is tissue damage and food trapping, such as the flap of gum tissue around a partially erupted molar. Examples of these bacteria include species such as Porphyromonas gingivalis and Fusobacterium nucleatum. They are known to contribute to the infection and inflammation associated with pericoronitis due to their ability to evade the immune response and establish infection in anaerobic conditions. Understanding the microbial flora involved in pericoronitis can aid in developing effective treatment plans, which may include antibiotic therapy targeting these specific bacteria as well as addressing any obstructive tissue that promotes bacterial proliferation.
