is responsible for most of the early strength.
Biodentinetm contains tricalcium silicate
with additives such as powder and a liquid, containing Calcium chloride to speed up setting.
It is a compound mixture of hydrophilic tricalcium silicate
, tricalcium oxide, and tricalcium aluminate with some other oxides.

43], by means of scanning electron microscopy, dispersive energy X-ray, X-ray diffraction, and optical profilometry characterization techniques, observed that tricalcium silicate
is more bioactive than Portland cement.
Beta form of dicalcium silicate appears at 1300 oC to 1350 oC whereas tricalcium silicate
at 1400 oC to 1450 oC, during manufacturing process of Portland cement [1, 2].
Additions of calcium chloride also result in a decrease in the dormant or induction period in the hydration of tricalcium silicate
MTA is cement composed of tricalcium silicate
, tricalcium aluminate, tricalcium oxide, silicate oxide and bismuth oxide.
It contains tricalcium silicate
, tricalcium aluminate, tricalcium oxide, silicate oxide and other mineral oxides forming a hydrophilic powder which sets in the presence of water.
Key words: acid neutralization; basicity; calcium phosphate cement; endo-materials; mineral trioxide aggregate; setting time; tricalcium silicate
