The present invention provides a composition based on calcium aluminate cement (CAC) for application in endodontics, comprising: (a) a cement - Al2O3 (> 68.5wt%), CaO (< 31wt%), SiO2 (0.3-0.8wt%), MgO (0.4-0.5wt%), and Fe2O3 (< 0.3wt%); (b) additives: dispersant at a content of 0.4 to 0.8% by weight of the cement, a plasticizer at a content of 2.0 to 4.0% by weight of the cement, and a radiopaque agent at a content of 20 to 35% by weight of the cement; and (c) water, wherein water/cement ratio lies in the range of 0.19-0.24 in the presence of additives. Cementitious product obtained thereof, after setting time, is also disclosed and characterized by enhanced properties when compared to the most used commercial repair cement, MTA. |
