This can lead to less favorable long-term outcomes, such as in bone repair or secondary therapy. Inspired by the strong antibacterial activity of zinc and copper ions, we developed a nonstoichiometric dicalcium silicate (C 2 S) substituted by 5% or 10% Zn or Cu to endow it with appropriate multifunctions. It was found that the foreign ion substitution could inhibit free CaO content and

Strontium-Substituted Dicalcium Silicate Bone Cements

In the present study, we developed a Sr-incorporated dicalcium silicate (C2S) bone cement as a potential candidate for bioactive self-setting bone cement in orthopaedics and stomatology. The Sr-C2S powders containing 0.3–6.8% Sr in molar ratio were prepared by means of chemical co-precipitation, and the results of XRD analysis indicated the incorporation of Sr element into the lattice of C2S ...

Except for the bismuth oxide component, PC and MTA have a similar main composition of tricalcium and dicalcium silicate, which during hydration, produce calcium silicate hydrate gel and calcium hydroxide (CH). However, MTA showed lack of potassium, and less calcium dialuminate, and calcium sulfate unhydrated compared to type I PC (Parirokh Torabinejad 2010a).
