Comparison of physical & chemical properties of Angelus MTA and new endodontic restorative material.

ABSTRACT

In current study the Iranian New Endodontic Restorative Material (NERM) with Angelus MTA, has been compared in term of physical and chemical properties such as; PH, Compressive Strength, release of calcium ions, and final phase of each product and setting time. Five samples of each dental material were prepared based on ISO standards to survey the physical and chemical properties of NERM and Angelus MTA. Structural survey for both dental material revealed a similar crystal structure and no significant differences were observed in the microstructure of the NERM and Angelus MTA. Setting time in NERM and Angelus MTA samples was 25 and 17 minutes, respectively (P<0.05). Both materials tested were alkaline and released calcium, the results revealed a higher pH for MTA Angelus than for NERM. The compressive strength values of NERM were greater than the angelus MTA at 14 days. Thus, it can be concluded that NERM has better chemical and physical properties than the Angelus MTA, but Angelus MTA is preferred in terms of setting time. With more studies and considering the physical and chemical properties of NREM, it could be recommended for clinical application because of its accessibility and lower prices.
