Post and core restorations: does the ferrule effect influence success?


This review evaluating the presence or absence of a ferrule influences the failure rate in fibre-reinforced composite (FRC) post-and-core restorations included 4 studies. While the findings indicate no differences in failure rates between restoration with and with out a ferrule the quality of the evidence is low.

This update of a 2012 Cochrane review of the effectiveness of crowns or conventional fillings for root filled teeth found insufficient evidence to assess the effectiveness of either approach.

Similar performance from glass fibre–reinforced epoxy resin posts and titanium posts in endodontically treated teeth at 7 years


Yesterday (Dental Elf 14th Jan 2012) we looked at a review that compared cast and fibre posts in-vitro. Here we are looking at a trail that compares the use of more flexible, dentine-like (low Young modulus) glass fibre–reinforced epoxy resin posts (GFREPs) with rather rigid, stiff (higher Young modulus) titanium posts (TPs) in order to [read the full story…]

Review of in-vitro studies shows greater fracture resistance for cast posts

shutterstock_25133602 - Cast post & core on model

Endodontically treated teeth (ETT) are considered to be more brittle and subject to fracture. Posts are frequently used to restore ETT and use of the appropriate post material is considered important to a successful restoration.  The aim of this review of in-vitro studies was to compare the fracture load of ETT restored with cast of [read the full story…]

Glass fibre-reinforced posts performed better at 5 years in endodontically treated teeth


Post systems are used in the restoration of endodontically treated teeth where there has been significant loss of the clinical crown. A post provides a method to secure filing material to the tooth.  The aim of this trial was to  assess the survival rate of two different post systems after 5 years of service. Patients [read the full story…]
