What is the outer mineralized layer of the tooth crown called?

Explanation:
Enamel is the outer mineralized layer of the tooth crown. It is the hardest tissue in the body, highly mineralized and formed by enamel-forming cells called ameloblasts. Enamel covers the visible crown, providing a tough, protective surface for chewing and resisting wear, while the underlying dentin supports it and the pulp lies inside. Dentin sits beneath enamel and makes up most of the tooth’s bulk, cementum covers the root to anchor the tooth to the socket, and pulp is the soft tissue inside. Because the question asks for the outer mineralized layer of the crown, enamel is the correct choice.
