Depth of fracture determines which tooth tissues are involved. A primary enamel fracture means the fracture line is confined to enamel, with neither dentin nor pulp breached, and the root intact. Enamel is the hard, outer layer that covers the tooth and is not innervated, so a fracture limited to enamel typically causes no pain and does not expose dentin. If the fracture extended into dentin, you would expect sensitivity and a different classification (enamel-dentin fracture). If the fracture involved the pulp or the root, you would be dealing with a more serious injury requiring more extensive treatment. Therefore, the statement describing a primary enamel fracture is one that specifies enamel involvement only.
