Summary
This case study shows a rare horizontal root fracture that healed spontaneously for 15 years before causing an abscess. Histological analysis revealed cementum as the primary repair tissue, highlighting a unique healing response in dental trauma.
Area of Science:
- Dentistry
- Oral Surgery
- Dental Traumatology
Background:
- Horizontal root fractures are uncommon dental injuries.
- Dr. Andreasen's classification details four repair outcomes: calcified tissue, connective tissue, connective and bony tissue, or granulation tissue interposition.
Observation:
- A 27-year-old female presented with a dento-alveolar abscess 15 years after trauma to her anterior teeth.
- Radiographs showed a horizontal root fracture in the middle third of the left upper central incisor with irregular hard tissue formation at the fracture site.
Findings:
- The fracture exhibited spontaneous healing over 15 years.
- Histological examination identified cementum as the predominant component of the repair tissue at the fracture site.
Implications:
- This case demonstrates a rare instance of long-term spontaneous healing of a horizontal root fracture.
- The findings suggest cementum plays a significant role in the repair of such dental injuries, even after a prolonged period.
