On radiographs, silver points within root canals appear as what?

• A. Radiopaque lines
• B. Radiolucent lines
• C. No radiopacity
• D. Irregular shapes

Answer: (A)

Metallic endodontic filling materials, like silver points, block more X‑rays than the surrounding tooth structure. On a radiograph this shows up as a bright, radiopaque line that runs along the length of the root canal, reflecting the presence and position of the filling. The key idea is that metals are highly radiopaque, so they appear white on the image. This is distinct from radiolucent areas, which look dark, and from materials that don’t show up at all or that don't form a continuous line within the canal.
