Fracture resistance and fracture resistance after fatigue loading of 4 different post and cores in endodontically treated teeth.
This article discusses the fracture resistance of 4 post and core systems including a combined obturator/post system before and after fatigue loading. The obturator/post demonstrated the highest fracture resistance values. The use of a combined obturator/post with a single resin endodontic sealer/luting cement seems promising.
