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:
- 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.
- Pulp Therapy:
- Initiated root canal therapy for the coronal fragment to manage pulp necrosis and prevent infection.
- 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.
- 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.
