HOSA Dental Terminology Practice

Which structure is covered with cementum?

1. The enamel of the tooth

2. The crown of the tooth

3. The root of the tooth

4. The pulp of the tooth

The correct answer is: The root of the tooth

Cementum is a specialized bony substance that covers the roots of teeth. It plays a crucial role in anchoring the tooth to the underlying bone through the periodontal ligament. Unlike enamel, which covers the crown and is the hardest tissue in the human body, cementum is softer and can be remodeled in response to stresses, such as tooth movement during orthodontic treatment. The root is the portion of the tooth that extends below the gum line, and it is vital for the stability and support of the tooth in the dental arch. Therefore, this structure is correctly identified as being covered with cementum.
