When cementing a post, how effective are traditional cements on post retention according to the statements?

The effectiveness of traditional cements in post retention can vary based on a number of factors, including the material of the post, the type of cement used, and the technique of cementation. Traditional cements, such as zinc phosphate or glass ionomer, have been commonly used in the past and are known to provide a certain degree of retention. However, their bonding mechanisms are often mechanical, relying on the physical anchorage created by the post's surface texture.

In the context of the statements, the first statement likely refers to the effectiveness of traditional cements in creating an adequate bond for posts, which is considered to be true. Traditional cements can provide sufficient retention, but their performance may not match that of newer resin-based cements, which involve chemical bonding with the post material and can enhance post retention significantly.

The second statement might pertain to the comparative performance of traditional cements in retaining posts versus contemporary materials. If this statement is presented with evidence that highlights a limitation or potential disadvantage of traditional cements in certain scenarios, it would also be considered true.

Therefore, the overall evaluation is that the first statement regarding traditional cements’ effectiveness in post retention is acceptable, while the second statement reflects a more critical view of their limitations, contributing to
