Dilaceration to permanent teeth is due to damage during what step?

  1. Calcification

  2. Eruption

  3. Apposition

  4. Root Formation

The correct answer is: Root Formation

Dilaceration to permanent teeth occurs when there is a sharp bend or curve in the root or crown of the tooth, usually due to trauma during the root formation stage. This trauma can cause abnormal growth in the developing tooth structure, resulting in an irregular shape. During root formation, any injury or damage to the tooth bud can lead to dilaceration. The other options - calcification, eruption, and apposition - are important stages in tooth development but are not specifically associated with the formation of dilacerations.
