Question

Odontoblast cells form ______________ of human teeth.

• A. enamel
• B. cement
• C. pulp cavity
• D. dentine

Answer 1

The correct option is D dentine

Odontoblast cells are columnar cells that emerge from the outer layer of the dentine pulp and forms the dentine of human teeth. Dentine is a cementing material that joins the enamel and the pulp. It provides support to the enamel and protects the pulp from microbes.
Enamel is the outermost layer of a tooth. It is the hardest part of the human body.
Cement is a bone-like substance that covers the dentine at the root region of the tooth. It helps in the joining of the tooth in the socket.
Pulp cavity consists of connective tissues, nerve fibres and blood vessels on one end and connects with the odontoblast cells that form the dentine on the other end.
