    Basics

    Description

    • Collection of pus in supporting structures of teeth:
      • Periodontal ligament
      • Alveolar bone
    • Periodontal pockets result from progression of periodontal disease and resultant bone loss:
      • Food and debris accumulate in periodontal pockets
      • Coronal epithelial tissues can reattach to tooth while bacteria and food debris remain trapped in pocket, impairing drainage
      • Food and debris become secondarily infected in the setting of impaired drainage
    • Complications:
      • Osteomyelitis
      • Dentocutaneous fistula
      • Cavernous sinus thrombosis
      • Ludwig angina
      • Maxillary sinusitis
      • Mediastinitis
      • Tooth loss
      • Sepsis

    Pediatric Considerations
    • Periodontal abscess is rare in children
    • Periapical abscess is more common:
      • Originates in pulp
      • Associated with caries

    Etiology

    • Anaerobic gram-negative rods
    • Peptostreptococci
    • Viridans group streptococci
    • Neisseria species
    • Usually polymicrobial
