Definition: A fracture involving enamel, dentin, cementum, and pulp.
Clinical Findings:
- Crown fragment attached to the root; visible pulp exposure with possible bleeding.
- Pain, tenderness on biting, and sensitivity to temperature changes.
Radiograph:
- Assess fracture extent and proximity to the pulp.
- Evaluate root involvement and apical health.
Treatment:
Vital pulp (open apex):
- Perform partial pulpotomy with calcium hydroxide or MTA.
- Restore with composite or crown after gingival adjustment if necessary.
- Non-vital pulp (closed apex):
- Perform root canal therapy.
- Restore with definitive restoration (e.g., crown).
- If fracture is subgingival, consider orthodontic extrusion or surgical crown lengthening.
Follow-Up:
- 6-8 weeks: Monitor for pulp healing and restoration stability.
- 1 year: Evaluate root health and healing.
Based on IADT guidelines. (Dent Traumatol 2012;28:2-12)

Intraoral Findings
Soft Tissues:
- Lacerations: Minor lacerations noted on the labial gingiva adjacent to tooth #8.
- Bleeding: Localized gingival bleeding near the fracture site.
- Swelling: Mild swelling noted around the affected area.
Tooth Findings:
- Tooth #8:
- Fracture: Crown-root fracture involving enamel, dentin, cementum, and pulp exposure.
- Mobility: Coronal fragment showed moderate mobility.
- Displacement: No significant displacement of the coronal fragment.
- Percussion: Tender to percussion.
- Sensitivity Testing (cold, electric pulp test): Negative response.
Radiograph
- Periapical and CBCT Imaging:
- Fracture line extending obliquely from the crown into the coronal portion of the root, involving the pulp chamber.
- No evidence of apical or root fractures beyond the coronal segment.
- Periodontal ligament space appeared intact apically.
Plan
Immediate Management:
- Fragment Management:
- The mobile coronal fragment was carefully removed to prevent further trauma.
- Pulp Therapy:
- Partial pulpotomy with calcium hydroxide or MTA was performed to preserve pulp vitality in an open apex.
- For a closed apex, complete pulpectomy/root canal treatment was initiated to address pulp necrosis.
- Temporary Restoration:
- Covered the exposed dentin with a glass ionomer dressing to prevent bacterial contamination and reduce sensitivity.
- Definitive Restoration Plan:
- Planned for crown lengthening or orthodontic extrusion to expose sufficient tooth structure for a definitive restoration.
- Definitive restoration (e.g., composite crown or porcelain crown) to be placed after sufficient healing and root therapy.
- Oral Hygiene:
- Advised meticulous oral hygiene with gentle brushing to avoid bacterial contamination.
- Recommended chlorhexidine rinse (0.12%) twice daily for 1 week to aid healing.
- Medications:
- Recommended ibuprofen 400-600 mg every 6-8 hours as needed for pain management.
- Antibiotics prescribed if signs of infection or significant soft tissue damage are present.
Follow-Up Schedule:
- 2 Weeks: Reassess soft tissue healing and evaluate pulp therapy progress.
- 4-6 Weeks: Plan for definitive restoration after root therapy and gingival healing.
- 3-6 Months: Radiographic and clinical monitoring for resorption or healing complications.
- 1 Year: Evaluate the stability of the definitive restoration and ensure periodontal health.
Warning About Risks Associated with Dental Trauma
Complicated crown-root fractures involving pulp carry risks such as pulp necrosis, root resorption, and periodontal complications. Regular follow-ups and prompt reporting of symptoms like pain, mobility, or discoloration are critical to ensure successful outcomes.
