Which feature is associated with a simple (traumatic) bone cyst?

The characteristic feature associated with a simple (traumatic) bone cyst is that it will scallop up between the teeth. This is due to its nature as a benign, cortically confined lesion that can expand and cause resorption of the adjacent bone, leading to a scalloped appearance on radiographs. This scalloping is a key radiographic feature that helps differentiate it from other lesions, as it signifies the cyst's growth pattern and its tendency to displace surrounding structures rather than simply pushing them away.

Unlike painful swellings, which may indicate other pathologies, and the notion that immediate surgical intervention is required, simple bone cysts can often be asymptomatic and may not necessitate urgent treatment. While these cysts can occur in various locations, they are not confined to the maxillary region; rather, they may be found in both the mandible and maxilla, often in the premolar or molar areas. Thus, the scalloping feature is primary in identifying a simple bone cyst on imaging and plays a significant role in diagnosis.
