What is the apex of a tooth?

1. The visible part of the tooth above the gum line

2. The root end of the tooth

3. The area where the tooth meets the jawbone

4. The point where the enamel and dentin meet

The correct answer is: The root end of the tooth

The apex of a tooth refers specifically to the tip of the tooth's root. It is an important anatomical landmark because it often houses the apical foramen, through which blood vessels and nerves enter the tooth. This area is crucial for the health of the tooth, as it facilitates the connection between the teeth and the surrounding supportive tissues. Understanding the significance of the apex is vital for dental procedures such as root canals, where treatment focuses on the area surrounding the apex to address issues like infection or damage. The other options describe different parts of the tooth, but none denote the root tip, making the identification of the apex as the root end the correct answer.
