**Core Concept**
The "Sharpened Pencil" appearance of the mandibular condyle on a radiograph is a characteristic feature of a specific condition affecting the temporomandibular joint (TMJ). This radiographic finding is associated with a particular type of joint disease that leads to changes in the bone morphology.

**Why the Correct Answer is Right**
The "Sharpened Pencil" appearance is a sign of condylar resorption, a condition where the mandibular condyle undergoes significant bone loss, resulting in a pointed or pencil-like shape on radiographs. This occurs due to the resorption of the cortical bone of the condyle, often as a result of inflammatory or degenerative joint disease, such as rheumatoid arthritis or osteoarthritis. The resorption process leads to the loss of the condylar cortex, creating the characteristic "Sharpened Pencil" appearance.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as the "Sharpened Pencil" appearance is not associated with a normal variation in the shape of the mandibular condyle.
* **Option B:** This option is incorrect as the "Sharpened Pencil" appearance is not a feature of a fracture or trauma to the mandibular condyle.
* **Option C:** This option is incorrect as the "Sharpened Pencil" appearance is not a characteristic feature of a benign tumor or cystic lesion affecting the TMJ.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that the "Sharpened Pencil" appearance is often associated with a poor prognosis for the TMJ, as condylar resorption can lead to significant functional impairment and limited treatment options.

**Correct Answer: C. Condylar resorption.**
