Pulpitis
Pulpitis
Inflammation of the dental pulp, the soft tissue inside a tooth.
Caries-induced Pulpitis
Caries-induced Pulpitis
Bacteria enter the dentine through tubules, causing inflammation of the pulp. This is the primary cause of pulpitis.
Trauma-induced Pulpitis
Trauma-induced Pulpitis
Trauma causes pulp exposure, allowing bacteria to invade and inflame the pulp.

Study Notes
Pulpitis Causes
- Caries: Dental decay (caries) exposes dentin, allowing bacteria to invade the pulp via dentinal tubules. This triggers a fluid movement effect. ICDAS 5 and 6 classifications indicate the extent of dentin invasion.
- Trauma: Fractures or physical trauma expose pulp, introducing bacteria. Deep lesions, thermal trauma (from restorative materials), and chemical irritation (from poor restoration seals) can directly harm the pulp.
- Perio-Endo Lesion: Untreated gum disease (periodontitis) can compromise periodontal structures, allowing bacteria to reach the pulp through the root canals. This can cause bone destruction. Caries affecting the pulp leads to pulp necrosis, abscess, and alveolar bone loss.
Pulpitis Clinical Signs and Symptoms
- Pain: Pulpitis pain is associated with specific nerves.
- Myelinated nerves (short, sharp pain): Found around pulp horns and coronal border. Reversible pulpitis involves these nerves; pain is temporary and relieved when the stimulus stops and may be caused by sensitivity to hot, cold, sweet, or sour.
- Unmyelinated nerves (dull, constant ache): Located deeper around the pulp core and apex. Irreversible pulpitis affects these nerves. Pain is severe, constant, often worse at night, and lingers. Loss of sleep is common, and pain relief often requires analgesics.
Diagnostic Assessment for Pulpitis
- History: Taking a thorough history, focusing on specific details about the pain:
- Tooth involved?
- What triggers pain?
- What relieves it?
- When does the problem occur? (e.g., time of day)
- Nature of pain (short/sharp/constant)?
- Analgesic use?
- Clinical Examination: Visual examination of the tooth:
- Identify problematic tooth/location.
- Observe tooth colour.
- Check for cavities, fractures, and restoration integrity (margins of existing fillings, depth & marginal ridge).
- Examine surrounding tissue for signs of inflammation.
- Special Tests:
- Thermal Tests: Using cold (e.g., ethyl chloride) and hot (e.g., gutta-percha) stimuli to assess sensitivity.
- Electric Pulp Test: Evaluating pulp vitality using electrical stimulation.
- Laser Doppler Flowmetry (LDF): Measures pulp blood flow.
- Radiological Examination: Bitewing and periapical radiographs to asses for decay and other abnormalities.
