Which term describes the portion of the tooth's internal pumping chamber inside the root?

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

Answer: (B)

The space inside a tooth that houses the nerves and blood vessels is the pulp space, which has two parts: the pulp chamber in the crown and the root canal inside the root. The portion inside the root is called the root canal. It runs from the pulp chamber down through the root toward the tip and is the area treated in root canal therapy. The other terms don’t describe this internal space: the root is the exterior part that anchors the tooth, a sextant is a way of dividing the mouth for measurement, and a suture is a surgical stitch.
