What is referred to as the part of the tooth covered by enamel?

1. Dentin

2. Root

3. Anatomical Crown

4. Gingiva

The correct answer is: Anatomical Crown

The part of the tooth covered by enamel is known as the anatomical crown. This term specifically refers to the visible portion of the tooth that is above the gum line and is covered by enamel, the hard, protective outer layer that provides strength and protects against decay. Enamel is the hardest substance in the human body, and its primary role is to shield the tooth from wear and damage from food and bacteria. Other parts of the tooth mentioned, such as dentin, root, and gingiva, serve different functions. Dentin is the layer beneath the enamel that makes up the bulk of the tooth and provides support but is not covered by enamel. The root is the portion of the tooth that is embedded in the jawbone, anchoring the tooth in place, and is covered by cementum rather than enamel. Lastly, gingiva refers to the gum tissue surrounding the teeth, providing protection and support but is not part of the tooth structure itself. Thus, the anatomical crown accurately describes the enamel-covered part of the tooth.
