Root Fracture: Findings, Treatment & Trauma Assessment Example

Definition: Fracture confined to the root, often classified based on location (cervical, middle, or apical third).

Clinical Findings:

  • Crown mobility may vary depending on fracture location.
  • Pain on biting or percussion.
  • Possible displacement of coronal fragment; no visible crown loss.

Radiograph:

  • Fracture line visible; may require multiple angled radiographs.
  • Cervical fractures are more challenging to manage than apical ones.

Treatment:

  • Reposition displaced fragments with digital pressure.
  • Stabilize using a flexible splint for:
    • 4 weeks for middle/apical third fractures.
    • Up to 4 months for cervical third fractures.
  • Monitor pulp vitality; treat necrosis in the coronal fragment if needed.

Follow-Up:

  • 4 weeks: Splint removal (longer for cervical fractures).
  • 6-8 weeks, 6 months, 1 year, 5 years: Monitor healing, vitality, and resorption.

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 around the affected area.

Tooth Findings:

  • Tooth #8:
    • Mobility: Marked mobility of the coronal fragment due to the cervical third root fracture.
    • Displacement: Coronal fragment was slightly displaced.
    • Percussion: Tender to percussion.
    • Sensitivity Testing (cold, electric pulp test): Negative, suggesting potential pulpal necrosis.

Radiograph

  • Periapical and CBCT Imaging:
    • Fracture line confirmed in the cervical third of the root.
    • Coronal fragment displacement observed with partial separation of the root structure.
    • No significant alveolar bone involvement was detected.

Plan

Immediate Management:

  1. Repositioning and Stabilization:
    • Repositioned the coronal fragment to align with the apical portion of the root.
    • Applied a flexible splint to stabilize the tooth and ensure immobilization.
    • Splint duration: 4 months due to cervical location of the fracture.
  2. Pulp Therapy:
    • Initiated root canal therapy for the coronal fragment to manage pulp necrosis and prevent infection.
  3. Soft Diet and Hygiene:
    • Advised a soft diet to minimize mechanical stress on the affected tooth.
    • Recommended chlorhexidine rinse (0.12%) twice daily to promote gingival healing and prevent infection.
  4. Medications:
    • Prescribed ibuprofen 400-600 mg every 6-8 hours for pain management.
    • Antibiotics were prescribed (e.g., amoxicillin) if the lacerations or tissue trauma were at risk of infection.

Follow-Up Schedule:

  • 4 Weeks: Clinical and radiographic reassessment to monitor splint stability and evaluate initial healing.
  • 4 Months: Remove splint and reassess mobility and healing of the root fracture.
  • 6-8 Months: Radiographic evaluation to monitor for resorption, healing complications, or ankylosis.
  • 1 Year and Beyond: Periodic monitoring for long-term healing and complications, including root resorption or failure of healing.

Warning About Risks Associated with Dental Trauma

Cervical third root fractures carry a high risk of complications such as pulp necrosis, root resorption, and non-healing of the fracture. Close monitoring and timely follow-ups are crucial to address potential issues and improve long-term outcomes.
