Question

Quizplus · Accepted Answer

Dentin is the living tissue located beneath the enamel and cementum layers of the tooth. It is similar to bone in its composition and functions to support the enamel and protect the pulp. Enamel is made up of minerals and is not living tissue, while cementum covers the root of the tooth and helps attach it to the jawbone. The pulp, located in the center of the tooth, contains nerves and blood vessels, but is not similar to bone. The periodontium refers to the supporting structures around the tooth, including the gums, periodontal ligament, and alveolar bone.
