What is the exposed portion of the tooth that is covered by enamel?

• A. Decay
• B. Dentin
• C. Crown
• D. Prophylaxis

Answer: (C)

Enamel covers the part of the tooth that you can see above the gum line, and that visible portion is called the crown. The crown is the part of the tooth that is exposed in the mouth and is covered by enamel for protection. The root, which sits below the gum, is protected by cementum, not enamel. So when the question asks for the exposed portion covered by enamel, the crown is the correct answer. Decay refers to a process that can affect enamel or dentin, dentin is the layer beneath enamel, and prophylaxis is a cleaning procedure, not a tooth part.
