Abstract : This research analyzed trace elements of crystal contained in powdered mineral trioxide aggregate (MTA) with SEM-EDS analysis. The results of this analysis were compared with trace elements, which have the possibility of appearing in the mineralization formation in dentine. Research has shown that some trace elements in the mineralization mechanism include Ca, P, S, Mg, Si, and Al in the root formation of dentin ; include Ca, P, S, and Mg at the completed root of dentin ; and Si and Al were replaced by Ca and P with the formation at the maturation of root. It is assumed that these trace elements of MTA are necessary for the mineralization process of dentine. We suppose that a vital reaction is further promoted by using these elements as a compound.
