Definition: A fracture involving enamel, dentin, and cementum, without pulp exposure.
Clinical Findings:
- Fractured crown fragment attached to the root; tender on biting.
- Fragment mobility may be observed; sensitivity to temperature or air due to exposed dentin.
Radiograph:
- Detect fracture line involving crown and root.
- Evaluate proximity to the pulp and extent of root involvement.
Treatment:
- Remove loose fragments.
- If fracture is above the gingival margin, restore with composite or crown.
- For subgingival fractures, perform gingivectomy or orthodontic extrusion before restoring.
Follow-Up:
- 6-8 weeks: Monitor restoration integrity and pulp vitality.
- 1 year: Reassess for pulp vitality and secondary complications like resorption or periodontal issues.

Intraoral Findings
Soft Tissues:
- Lacerations: Minor gingival lacerations noted around tooth #8.
- Bleeding: Localized gingival bleeding near the fracture site.
- Swelling: No significant swelling observed.
Tooth Findings:
- Tooth #8:
- Fracture: Crown-root fracture involving enamel, dentin, and cementum without pulp exposure.
- Mobility: Coronal fragment showed slight mobility.
- Displacement: No significant displacement of the coronal fragment.
- Percussion: Tender to percussion.
- Sensitivity Testing (cold, electric pulp test): Normal response, indicating pulp vitality.
Radiograph
- Periapical Radiograph:
- Fracture line extending obliquely from the crown into the coronal portion of the root.
- No signs of pulp exposure or root fracture beyond the coronal segment.
- Periodontal ligament space appeared intact apically.
Plan
Immediate Management:
- Fragment Management:
- The mobile coronal fragment was carefully removed to prevent irritation or further trauma.
- Temporary Restoration:
- Applied a glass ionomer dressing to cover the exposed dentin and protect it from thermal and bacterial irritation.
- Definitive Restoration Plan:
- Planned for crown lengthening or orthodontic extrusion to expose sufficient tooth structure for a permanent restoration.
- Definitive restoration (composite crown or porcelain crown) to be placed after sufficient healing and adjustment.
- Oral Hygiene:
- Advised meticulous oral hygiene with gentle brushing to prevent bacterial contamination.
- Recommended chlorhexidine rinse (0.12%) twice daily for 1 week to promote gingival healing.
- Medications:
- Recommended ibuprofen 400-600 mg every 6-8 hours as needed for pain management.
Follow-Up Schedule:
- 2 Weeks: Evaluate healing of soft tissues and stability of temporary restoration.
- 4-6 Weeks: Reassess the tooth for definitive restoration planning (e.g., crown placement or orthodontic extrusion).
- 3-6 Months: Periodic radiographic monitoring for signs of root resorption or other complications.
- 1 Year: Ensure long-term stability of the definitive restoration and evaluate for periodontal health.
Warning About Risks Associated with Dental Trauma
Crown-root fractures, even without pulp exposure, carry risks such as root resorption, periodontal complications, and delayed healing. Regular follow-ups and reporting of symptoms like increased mobility, pain, or discoloration are essential to ensure successful treatment outcomes.
