Abstract

Objectives: The aim of this study was to evaluate the suitability of fast-setting cement formulations based on Portland cement as dental core build-up materials using two different methods of testing compressive strength and evaluation of setting times. Methods: Four fast-setting cements based on Portland cement and their four respective densified with small particle (DSP) mortars were tested for setting time, constitution of cement by EDAX, and compressive strength using International and British Standards. Ordinary Portland cement (OPC) was used as a control. Results: All the fast-setting cements had a similar elemental composition to OPC and the setting times were less than 7 min. The compressive strength of OPC was different between the two methods (P0.05), but the cylinders showed a tower compressive strength at 28 days (P
