Research Abstract

In the minimal intervention, apatite cement was sometimes used as a syringe injection. High liquid to powder ration of the apatite cement aiming to improve the handling property leads to the decrease in the mechanical strength of the set cement. So the new method to improve the wettability of the apatite cement is needed. In this study, the effect of ozone treatment on the mechanical strength and operability of the apatite was demonstrated. After the ozone treatment, the DTS values are twice higher than that of non-treated one.
