What is the primary source of retention for passive posts?

The threaded design of the post

The luting cement used for cementation (correct)

The frictional resistance between the post and the root canal

The mechanical adaptation of the post to the dentin walls

What is the potential risk of screwing a post into the root canal?

Dentin hypersensitivity

Inadequate cementation

Vertical root fracture (correct)

Insufficient retention of the post

What is the advantage of quartz fiber posts in terms of root fracture potential?

They are more flexible than traditional metal posts

They appear to be advantageous with regard to root fracture potential (correct)

They produce less stress concentration at the coronal portion of the root

They are more resistant to corrosion
