Abstract
The synthesis of a new endodontic mixture based on calcium aluminate cement is reported. Physico-chemical and mechanical properties of the mixture were investigated before and after various hydration periods. Phase analysis of the mixture was performed using X-ray diffraction (XRD), while morphological analysis was performed by scanning electron microscopy (SEM) equipped with EDS which revealed elemental composition of the mixture sample. Investigations of mechanical properties showed that this new endodontic mixture possessed good mechanical properties (compressive strength after 28 days aging was 94 MPa) and relatively short setting time (2 h). Additionally, cytotoxicity of the mixture was investigated by MTT assay, while genotoxicity was investigated by Comet assay, using MRC-5 cell line. The obtained results make this material very promising for potential application in dental practice.
