Radiographic appearance categories for idiopathic osteosclerosis include which of the following?

• A. Corticated
• B. Diffuse
• C. Well Demarcated
• D. Irregular

Answer: (C)

Idiopathic osteosclerosis shows up as a localized, dense radiopacity within the jawbone with a clearly defined border. The essential idea is that it forms a sharp, well delineated area that stands out from the surrounding bone. This crisp boundary helps distinguish it from lesions that look diffuse or have irregular outlines. While some benign conditions can have different border styles, the characteristic radiographic appearance of idiopathic osteosclerosis is a well demarcated lesion, making that descriptor the best choice.
