Correct answer: D — Damage to the developing permanent tooth germ
Intrusion of a primary incisor carries the highest risk of damage to the developing permanent successor because the apex of the primary incisor is in close proximity to the permanent tooth bud palatally. Depending on the direction of displacement, the intrusive force can directly traumatize the developing tooth germ, causing enamel hypoplasia, dilaceration, arrested root development, or eruption disturbance of the permanent successor. Most intruded primary incisors are left to re-erupt spontaneously.
