Fibre Post Questionnaire:

1: The concept of decreasing the likelihood for fracture using a circumferential ferrule does not apply to bonded fibre posts.



  1. True*

  2. False

2: Fibre reinforced bonded posts and bonded composite cores show significantly stronger crown retention than cast gold dowels and titanium alloy dowels with composite cores.

  1. True*

  2. False

3: One of the advantages of using fibre posts with bonded cements and bonded cores is the decrease in the potential for root fracture.

  1. True*

  2. False

4: Cast post and cores have a better performance than direct post and core restorations.

  1. True

  2. False*

5: Stiff metallic posts work against the natural function of the tooth, creating zones of tension and shear, both in the dentine and at the interfaces of the luting cement and post.

  1. True*

  2. False

6: With static and fatigue fracture testing under vertical or oblique loadings, the fracture loads of the teeth restored with fiber posts are significantly greater than those of teeth restored with metallic posts.

  1. True*

  2. False

7: The more rigid metallic post can transfer more stress to the root than fiber posts, which increases the probability of root fracture.

  1. True*

  2. False

8: If a fibre post fails clinically, it is more likely to result in a repairable failure than when metallic posts are used.

  1. True*

  2. False

9: Parallel sided posts result in more apical dentin removal resulting in significant weakening of the tooth structure.

  1. True*

  2. False

10: A tapered fibre post results in better adaptation to the root shape and results in less composite luting agent resulting in less likelihood for microleakage causing endodontic failure.

  1. True*

  2. False

11: When etching the canal prior to the bonding procedure any acid etch and tip combination will result in adequate etching of the canal.

  1. True

  2. False*

12: When creating a fibre post and core system separate cement and core material must always be used.

  1. True

  2. False*

13: All fibre posts are essentially the same, and there is very little difference between the various brands currently available.

  1. True

  2. False*

14: All current bonding agents can be used with dual cure and self cure cements that are currently used with fibre posts.

  1. True

  2. False*

15: It makes no difference whether you cut the post with a diamond bur, carbide bur or diamond disc prior to cementing the post.

  1. True

  2. False*

16: All core materials cut like dentin.

  1. True

  2. False*
