Questions and Answers

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
