Which bacteria are commonly found in pericoronitis?

• A. Staphylococcus aureus
• B. Fusobacterium, Strep milleri, Peptostreptococcus
• C. Escherichia coli, Pseudomonas aeruginosa, Streptococcus pneumoniae
• D. Clostridium botulinum, Listeria monocytogenes, Actinomyces israelii

Answer: (B)

Pericoronitis is an inflammation of the soft tissue surrounding a partially erupted tooth, most commonly seen with the third molars. In the context of pericoronitis, the microbial flora typically involved consists of anaerobic and microaerophilic bacteria, which thrive in the subgingival environment often seen in cases of pericoronitis. The correct answer highlights specific bacteria known to be associated with the condition. Fusobacterium is an anaerobic bacterium that is often implicated in periodontal diseases, including pericoronitis, as it can evade the host's immune responses in the gingival environment. Streptococcus milleri, part of the Streptococcus anginosus group, is also recognized for its role in oral infections and can be part of the polymicrobial flora associated with abscesses and periodontal disease. Peptostreptococcus, another anaerobic bacterium, is frequently found in deep tissue infections and periodontal infections due to its ability to survive in low-oxygen conditions. In contrast, the other provided choices include bacteria that are less commonly associated with pericoronitis. Staphylococcus aureus, while a significant pathogen in various infections, is not typically linked to pericoronitis. The group involving Escher
