1. Why do we need to classify pulpal and periradicular diseases?
    • 1. To determine the treatment plan (RCT, surgery, antibiotics)
    • 2. To assess the treatment outcome (diagnosis affects prognosis)
  2. What is Reversible pulpitis?
    • A reactive inflammatory process
    • radiographically normal
    • pain with pressure and temperature
    • self limiting inflammation with time and insult removal
    • Monitor first before RCT
    • EX: incipient caries, acute trauma, restorative procedure

  4. What is irreversible pulpitis?
    • Irreperable pulpal injury
    • Spontaneous sharp pains
    • sensitive to cold/hot (lingering sensitivity)
    • Can progress to necrosis if untreated

  6. What is pulpal necrosis?
    • Complete loss of vitality
    • Mostly asymptomatic
    • Can be partially necrotic in multi-rooted teeth
  7. What is hyperplastic pulpitis?
    • Pulp polyps
    • prevalent in young patients
    • usually asymptomatic
    • highly vascularized
  8. Acute periradicular periodontitis
    • Main issues are with pressure. Cannot chew
    • always linked with pulpal disease
    • No PARL, but thickened PDL
    • Needs RCT
  9. Chronic periradicular periodontitis
    • Occasional 'acting up'. No major symptoms
    • Always linked with infected pulp necrosis
    • Distinct PARL radiographicallyImage Upload 4
  10. Acute periradicular abscess
    • Facial swelling and extreme pain
    • ALWAYS linked with pulp necrosis
    • Distinct PARL
    • Needs incision and drainage with antibiotics
  11. Chronic periradicular abscess
    • No major symptoms
    • Always linked with pulp necrosis
    • radiographically distinct PARL
  12. Chronic periradicular Abscess

  13. Condensing osteitis
    • Variant form of CPP
    • Increase in bone density
    • Little or no pain
    • Linkd with necrotic pulp in mandibular molars
