Exploring a new Portland cement-free calcium silicate cement -Part 1: Synthesis of dicalcium and tricalcium silicate.

Mineral trioxide aggregate cement is an excellent pulp-capping material; however, its base Portland cement contains highly toxic elements and is expensive. This study aimed to explore the possibility of using calcium silicate cement without Portland cement. Synthesis was attempted via firing using calcium silicate (CS), as the base material, and calcium oxide (CA).
