Mechanical and microstructural characterisation of new calcium aluminate cement (EndoBinder)
The aim of this study was to carry out a mechanical and microstructural characterisation of calcium aluminate cement [EndoBinder (EB)] by compressive and diametral tensile strength tests, Vickers microhardness test and scanning electron microscopy analysis. Test specimens were made according to the type of cement used [EB, grey mineral trioxide aggregate (GMTA) and white mineral trioxide aggregate (WMTA)] and the setting time tested (24 h, 7 days and 21 days). The mean values obtained after mechanical tests showed that EB presented higher compressive strength, with statistically significant difference to WMTA (7/21 days), and higher diametral tensile strength, with statistically significant difference to GMTA (7/21 days) and WMTA (21 days). EndoBinder presented higher microhardness values, differing statistically from GMTA (21 days) and WMTA (7/21 days). The SEM analysis showed a more homogeneous microstructural arrangement for EB, with particles of uniform size and shape. EndoBinder presented adequate mechanical properties, frequently superior to mineral trioxide aggregate, making it a feasible option for endodontic treatment.
