Definition: A region of fibrous tissue formation instead of bone after extraction or surgery.
Radiographic Features:
- Location:
- Any site of previous surgery or extraction
- Sometimes seen at the apex of endodontically treated teeth where infection/inflammation didn’t heal with bone
- Edge:
- Well-defined
- Characteristic ‘rolled’ appearance (likened to a bundt pan)
- Shape: Round to ovoid
- Internal structure: Radiolucent
- Number: Typically single, but may be multiple
Key points:
- Represents normal healing in some cases
- More common in maxilla than mandible
- Generally asymptomatic and stable over time
Clinical significance:
- Usually doesn’t require treatment
- Important to differentiate from pathological lesions
- May complicate implant placement or other surgical procedures in the area
- Regular monitoring recommended to ensure stability
Note: Correlation with patient history of previous procedures is crucial for accurate diagnosis. If the lesion shows changes over time or is symptomatic, further investigation may be necessary to rule out pathology.
