Abstract

Objectives: The aim of this study was to investigate the effect of different core materials on the fracture strength of endodontically treated roots. Materials and Methods: Twenty-one (CAD/CAM zirconia post) posts were cemented to the central incisors with a resin cement (Rely X Unicem). After fabrication of core restorations (zirconia, resin core, resin composite), the metal crowns were fabricated on these cores and cemented with a polycarboxylate cement. Each specimen was embedded in an acrylic resin mold. A compressive load was applied on the lingual surface (2 mm below the incisal edge) at 45º angle and crosshead speed of 0.5 mm/min until a fracture occurred. Then fracture strength was measured using a universal testing machine. Data were analyzed using one-way analysis of variance and Tukey tests (p
