In the Ellis classification, which category corresponds to enamel fracture?

• A. Enamel and dentin fracture
• B. Enamel fracture
• C. Enamel, dentin, and pulp fracture
• D. Root fracture

Answer: (B)

In this classification, fractures are grouped by how much tooth structure is damaged. An enamel fracture means only the enamel is broken, with no exposure of dentin and no involvement of the pulp. That simple, enamel-only damage is what the Ellis system calls an enamel fracture. Because there’s no dentin exposure or pulp involvement, the prognosis is excellent and treatment is usually minimal, such as smoothing the chipped edge or bonding for esthetics. If dentin were involved, you’d have an enamel and dentin fracture; if the pulp were exposed as well, it would be an enamel, dentin, and pulp fracture; and a root fracture refers to damage in the root itself, not just the crown.
