Zusammenfassung:A novel amorphous divalent metal ion salt for enhancing the manageability of a Portland cement and its application in dental field are disclosed. Typical formula (I), (II), or (III) of this amorphous metal ion salt are shown as following: wherein, M2+, A-, B-, C-2, D-3, x, y, and z are defined the same as the specification. The manageability of Portland cement includes short setting time and tendency of cement paste sticking together. A novel tooth filling material comprises: a Portland cement, a bone substitute substance, and an amorphous divalent metal ion salt with formula of (I), (II), or (III). In addition, a novel root canal filling material comprises: a Portland cement, a radiopaque substance, and an amorphous divalent metal ion salt with formula of (I), (II), or (III). This amorphous divalent metal ion salt in the filling material of the present invention can improve the sticking together and reduce the setting time, thus offering more convenient in dental applications.
