Fiber-reinforced Composite Core Filling in the Restoration of Endodontically Treated Molars - a Clinical Study.

Summary

A short fiber reinforced composite base filling material has been shown to improve the strength of a direct composite filling significantly. It prevents fracture propagation and reduces shrinkage strain. These features are needed especially in endodontically treated molars, as root-canal treated teeth are structurally compromised and their restoration is associated with technical failures such as debonding and vertical root fractures.

Application on this core fiber-reinforced composite (FRC) material is simplified when compared to post and core techniques commonly used to restore endodontically treated teeth. Clinically, the use of core FRC offers a cost-effective way to restore endodontically treated molars without root canal involvement.

The purpose of this study is to compare the clinical performance of endodontically treated molars restored with either direct composite restorations with a FRC substructure, or with indirect full-ceramic onlay restorations, i.e. endo-crowns.
