Fracture resistance of fiber post in endodontically treated teeth

TL;DR

This study compares the fracture resistance of different fiber posts in endodontically treated teeth using various cements.

Contribution

The study evaluates the performance of custom-made and prefabricated fiber posts with different resin cements in enhancing fracture resistance.

Findings

GC Everstick post showed better fracture resistance compared to other posts regardless of cement used.

Maxcem elite resin cement provided higher fracture resistance than GC Fujicem cement.

Abstract

Management of an endodontically treated tooth is a challenging task. Post and core procedure helps to enhance the fracture resistance
of endodontically treated teeth. Hence the present study was done to evaluate the fracture resistance of custom made GC Everstick post
to prefabricated Tenax fiber post and Angelus Reforpostluted with two different resin cements on endodontically treated teeth. Sixty
extracted human mono-radicular teeth were included. They were endodontically treated and standardized to 15mm from the root apex and
then decoronated. The specimens were randomly divided into 3 groups and each group was further alienated into 2 subgroups. The teeth
were randomly selected and treated with an Everstick post, Angelus reforpost, Tenax trans fiber post and were cemented using Maxcem
elite and GC Fujicem cement. The core was standardized to 4mm. All the Samples were thermocycled and embedded in the acrylic resin
blocks then subjected to compressive load of 1mm/min at 1350 angulation to evaluate the fracture resistance. Thus, we show that the GC
Everstick Post showed better fracture resistance when compared to other post irrespective of the resin cement used.Maxcem elite resin
cement provided better fracture resistance.
