      • Traumatic infection
      • Hematogenous infection
      • Iatrogenic infection
    • Odontogenic infection
      • Periapical infection
      • Pericoronitis

    • Pathways of Periapical infection
    • Pericoronitis Lower third molar
    • Infection---Arising
      • Host--- defense system
      • Microbe---virulence quantity
      • Local circumstance
      Balance Imbalance Scale
    • Mutation
      • Influence factors
      • Changing directions

    • How to diagnose?
      • Local Signs and Symptoms
      • Systemical Signs and Symptoms
      Signs and Symptoms
    • Local Signs and Symptoms
      • Pain
      • Swelling
      • Surface erythema
      • Pus formation
      • Limitation of motion
      Locally
    • Systemical Signs and Symptoms
      • Fever
      • Lymphadenopathy
      • Malaise
      • Toxic appearance
      • Elevated white blood cell count
    • How to treat?
      • Acute stage
      • Chronic stage
    • Acute stage
      • Host
      • Antibiotic therapy
      • Surgical drainage and incision
    • Host
      • Migration of white blood cell
      • Production of antibodies
      • Most important factor --- final outcome
      • The infections--- cured by the host, not by antibiotics
      Critical Principles Defense Mechanisms
    • Principles for choosing appropriate antibiotic
      • causative organism
      • sensitivity
      • specific, narrow-spectrum antibiotic
      • least toxic antibiotic
      • drug history(success, allergic and toxic)
      Antibiotic era
    • Principles of antibiotic administration
      • Proper dose
      • Proper time interval
      • Proper route of administration(oral, parenteral)
      • Combination antibiotic therapy
    • Surgical drainage and incision
      • How to judge the pus formation?
      • Purposes of surgical drainage and incision
      • Principles of surgical drainage and incision
    • How to judge the pus formation?
      • Three stages
      • Inoculation
      • Cellulitis
      • Abscess
      • Duration--- >5 days
      • Palpation---Fluctuant
      • Appearance---Reddened
      • Needle aspiration
      • B-ultrasound
      • CT
      Characteristic
    • Fluctuant examination
    • Purposes of surgical drainage & incision
      • Rid the body of toxic purulent material
      • Decompress the tissues
      • Allowing better perfusion of blood containing antibiotics and defensive elements
      • Increased oxygenation of the infected area
    • Infection in masseteric space
    • Infection in multi-space Ludwig’s angina
    • Principles of surgical drainage & incision
      • Place the incision in an esthetically acceptable
      • Place the incision in a dependent position to encourage drainage by gravity
      • Dissect bluntly through deeper tissues and explore all portions of the abscess
      • Place a drain and stabilize it with sutures
    • Principles of surgical drainage & incision
      • Lesion tooth---Impacted tooth
      • Osteomyelitis
      Chronic stage Surgical removal of the focus

      • The trait of Infection
      • Odontogenic infection
      • mutation of infectious
      • Diagnosis of the infection
      • Diagnosis of the abscess formation
      • The principles of the treatment
