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

Root Formation
Calcification
Apposition
Eruption

The correct answer is: Apposition

Hypoplasia to permanent teeth is the underdevelopment or incomplete development of teeth, which can lead to various dental issues. This condition is caused by damage to the enamel during tooth formation. While root formation (A), calcification (B), and eruption (D) are all important stages in tooth development, they are not the cause of hypoplasia. Apposition (C) is the stage where enamel is deposited and begins to harden, making it the critical time for potential damage that may result in hypoplasia. Therefore, C is the correct answer.
