The width of a post should not exceed what fraction of the root diameter?

The correct answer is: 1/3

The correct answer is 1/3 because the width of a post should ideally not exceed one-third of the root diameter to maintain a proper ratio for the restoration's durability and stability. If the post is too wide in relation to the root diameter, it can compromise the structural integrity of the tooth and can lead to potential complications in the future. Therefore, ensuring the appropriate ratio between the post width and the root diameter is crucial for the long-term success of the dental restoration.
