Periapical abscess

Classification

• Periapical abscess: The result of a chronic, localized infection located at the tip, or apex, of the root of a tooth.
• Periodontal abscess: begins in a periodontal pocket (see: periodontal abscess)
• Gingival abscess: involving only the gum tissue, without affecting either the tooth or the periodontal ligament (see: periodontal abscess)
• Pericoronal abscess: involving the soft tissues surrounding the crown of a tooth (see: Pericoronitis)
• Combined periodontic-endodontic abscess: a situation in which a periapical abscess and a periodontal abscess have combined (see: Combined periodontic-endodontic lesions).
