II. Definition

  1. Inflammation of the dental pulp

III. Pathophysiology

  1. Tooth defect allows for dental pulp exposure to pathogens
  2. Predisposing defects in the tooth
    1. Dental Caries
    2. Tooth Fracture
    3. Apical foramen defect
  3. Course
    1. Initial: Tooth cavity develops
    2. Reversible Pulpitis
      1. Mild inflammation from encroaching pathogenic material
    3. Irreversible Pulpitis
      1. Pulp chamber is rigid and does not accomodate increased pressures
      2. Pressure occludes apical foramen vessels
      3. Dental pulp tissue necroses

IV. Symptoms

  1. Reversible Pulpitis: Mild tooth pulp inflammation and encroachment
    1. Pain triggered by hot, cold or sweet stimuli
    2. Provoked by lying supine
  2. Irreversible Pulpitis: Progresses from Reversible Pulpitis
    1. Severe tooth pulp inflammation
    2. Pain is severe, persistent and poorly localized
    3. Pain may radiate to ear, temple, eye or neck

V. Management

  1. Reversible Pulpitis
    1. Dental Caries debris removed
    2. Dental filling applied
  2. Irreversible Pulpitis
    1. Root canal or Tooth Extraction
    2. Do not delay management more than a few days

VI. Complications (of Irreversible Pulpitis)

Definition (NCI) Inflammation of the dental pulp.
Definition (MSH) Inflammation of the DENTAL PULP, usually due to bacterial infection in dental caries, tooth fracture, or other conditions causing exposure of the pulp to bacterial invasion. Chemical irritants, thermal factors, hyperemic changes, and other factors may also cause pulpitis.
