Correct answer: D — Risk of damage to the developing permanent successor based on the direction and severity of displacement

The decision to extract or observe a traumatised primary tooth depends primarily on whether the injury poses a risk to the developing permanent tooth germ. Intrusive luxation (where the primary root apex is driven toward the permanent tooth bud) and severe displacement injuries carry the highest risk of damage to the permanent successor (enamel defects, dilaceration, eruption disturbance). If the primary tooth root is displaced toward the permanent tooth bud, extraction is recommended. If displaced away (labially), observation is usually appropriate.
