The study was done to compare the compressive strength of two core building materials namely Group 1 CoremaxII and Group 2 Ketac Silver. For the purpose of study 20 freshly extracted teeth were taken and endodontically treated. Two groups were made Group 1 Coremax II, Group 2 Ketac Silver. Core build was done and tested under universal testing machine under a compressive load. Study proved that group 1 had significantly high strength then group 2
