A Correct answer
Explanation

A tooth whose restoration may require a post and core usually is filled with Gutta percha or sectional/split cone silver cone. The cone is notched 6 mm from the apical tip, and it is sterilized and is cemented in the root canal. The wedged cemented cone is rotated until it breaks at the notch, and the free end is removed to leave enough space for preparation of a post.
