1. Introduction - Hindawi Publishing Corporation
One material that is considered to have remineralizing properties and the necessary mechanical properties to function as a dental material is calcium aluminate (CA) [5, 6]. The main mechanism behind bioactive properties of a material has been connected to its negatively charged surface and its release of calcium, phosphate, and hydroxyl groups.

Blends of ordinary Portland cement (OPC) and calcium aluminate cement (CAC) exhibit a very fast setting over a wide range of OPC/CAC ratios. Figure 1 shows a typical example of such behavior, but the exact setting time will also depend strongly on the characteristics of the individual cements employed, and on the water/solid ratio of the mix.

For analysis of cement powders, in addition to the backstered electron signal, X-ray images are collected for Ca, Si, Al, Fe, S, K, and Mg. Because these X-ray images are collected at the same loion as the backstered electron image, this series of images can be coined to determine the mineral phase present at each loion (pixel) in the two-dimensional image (typically 512 pixels

The pure fused calcium aluminate performed better than the regular calcium aluminate in the test conducted. What is clear, though, is that the epoxy modified mortar was by far the best performer. The weight loss was far less for the epoxy modified mortar than for the calcium aluminate or pure fused calcium aluminate(1.14% loss vs. 56.61% and 40.28%, respectively).
