Which term describes the nerve of the tooth removed from the canal inside the roof and replaced with a filling material?

• A. Root canal
• B. Root
• C. Suture
• D. Root canal treatment

Answer: (D)

The key idea is understanding what the term refers to: the procedure of removing the tooth’s pulp tissue (nerve inside the canal) and filling the space to seal it. That complete process is called root canal treatment. The space itself, the root canal, is simply the hollow passage inside the tooth that used to contain nerves and vessels. It’s not the act of removing and filling. The other terms don’t fit because the root is the part of the tooth, and a suture is stitching material for soft tissues. So, removing the nerve from the canal and then filling it describes root canal treatment.
