| Feature | Favors Cyst | Favors Tumor (e.g. ameloblastoma) |
|---|---|---|
| Border | Well-defined, corticated (thin radiopaque rim) | May be well- or ill-defined; margins can be scalloped |
| Locularity | Usually unilocular | Often multilocular - classic "soap bubble/honeycomb" pattern |
| Growth pattern | Slow, hydraulic/expansile pressure producing smooth cortical expansion | Can cause frank cortical perforation and soft-tissue extension |
| Root resorption | Rare, usually just root divergence/blunting | More common and more aggressive, especially with ameloblastoma |
| Tooth displacement | Common (cyst pushes adjacent teeth) | Also common, but roots can additionally be resorbed rather than just displaced |
