A periapical abscess that is draining can resemble which of the following?

Question

Quizplus · Accepted Answer

A periodontal abscess can present with similar symptoms to a draining periapical abscess, as both involve localized swelling, pain, and when drained may produce purulent exudate. However, a periodontal abscess typically arises from infection within the periodontal pocket and involves destruction of the surrounding periodontal tissues, while a periapical abscess arises from a dental pulp infection and involves the destruction of bone at the apex of the affected tooth. Pericoronitis (A) is the inflammation of the soft tissues surrounding a partially erupted tooth, typically a wisdom tooth, and is not related to a periapical abscess. An allergic reaction (B) would not be related to dental pathology, and linear gingival erythema (D) is a clinical presentation of HIV-associated periodontitis that is not associated with abscess formation.
