Stages of Odontogenic Infections: Comparison of inoculation vs Cellulitis vs abscess

Odontogenic infections arise from the progression of aerobic and anaerobic bacteria through caries, necrotic pulp and deep periodontal pockets. As the progression occurs the infection shows different stages Clinically. Thus, Odontogenic infections seem to pass through four stages.

  • Inoculation Stage:
    • Duration: (0-3 days)
    • Soft, mild tender on palpation and doughy swelling
    • Initial stages in which gm positive cocci( Streptococci) are invading and colonizing the host.

  • Cellulitis Stage:
    • Duration: 1-5 days
    • Hard, red, inflamed, and tender due to intense inflammatory response
    • Mixed bacteria is (both aerobic and anaerobic) are predominate in this stage
  • Abscess Satge:
    • Duration: 4-10 days
    • Soft, smaller and mild tender swelling 
    • Anaerobic bacteria predominate causing liquefied abscess in this stage 
  • Resolution stage: 
    • After the  abscess drains spontaneously through skin and mucosa or it is surgically drained, resolution stage begins.
    • The host immunity system destroys infecting bacteria
    • The process of healing takes place
