Purpose: To evaluate and compare the fracture toughness and flexural strength of four different core build up materials. Materials and methods: Sixty samples were taken for study, which were equally divided into four groups. Group A includes dual cure composite resin reinforced with zirconia filler particles (Luxacore Z, DMG), group B-light cure composite resin (Lumiglass deepcure, RDT France), group C-zirconia reinforced glass ionomer cement (Zirconomer improved, Shofu) and group D-chemically cure composite resin (Self comp, Prevest Denpro). All the core build up materials were manipulated according to manufacturer’s instructions and poured into mold. A Universal testing machine applied a central load to the specimen in a 3-point bending mode. Fracture of the specimen was identified and the reading recorded by the universal testing machine. The data were analys.. Read More»
