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.
