The BioRoot RCS is a hydraulic tricaclium-based cement that contains tricalcium silicate, zirconium oxide, calcium chloride, povidone, and polycarboxilate.
[16] The powder component of the material consists of tricalcium silicate, dicalcium silicate, calcium carbonate and oxide filler, iron oxide shade, and zirconium oxide, respectively, whereas zirconium oxide serves as a radio-opacifier.

The alkalinization of the medium and release of calcium ions are related to the formation of portlandite (calcium hydroxide) by tricalcium silicate and dicalcium silicate during the setting time of MTA.

Tricalcium silicate ([Ca.sub.3][Si[O.sub.4]]O, PDF#01-073-2077) was evident only in the PBS and control groups of the BC sealer (Figures 2(c) and 2(d)).
Most important reactions are tricalcium silicate and dicalcium silicate reacting with water to produce calcium silicate hydrates (C-S-H) and calcium hydroxide [Ca [(OH).sub.2]].
Upon the addition of water, tricalcium silicate rapidly reacts to release calcium ions, hydroxide ions, and a large amount of heat.
