Randomized clinical study comparing metallic and glass fiber post in restoration of endodontically treated teeth.

Background: Post-retained crowns are indicated for endodontically treated teeth (ETT) with severely damaged coronal tissue. Metallic custom and prefabricated posts have been used over the years, however, due to unacceptable color, extreme rigidity and corrosion, fiber posts, which are flexible, aesthetically pleasing and have modulus of elasticity comparable with dentin were introduced.

Aim: To compare clinical performance of metallic and glass fiber posts in restoration of ETT.
