Correct answer: A. Enamel tufts
- A. Enamel tufts
- B. Enamel lamella
- C. Incremental lines of enamel
- D. Enamel cuticle
Explanation
Enamel tufts are hypomineralised structures that arise at the dentinoenamel junction and extend inward, so they are not an external surface feature. Enamel lamellae and the enamel cuticle reach or arise from the enamel surface, while incremental lines may appear externally as perikymata.
