The purpose of this study was to investigate the influence of different radiopacifiers on the physicochemical and biological properties of novel calcium silicate based endodontic ceramic enriched with bioactive nanoparticulated hydroxyapatite - ECHA. Namely, ECHA was used as a basis for mixing with the following radiopacifiers: strontium fluoride (SrF2), zirconium dioxide (ZrO2) and bismuth oxide (Bi2O3). For comparison, Portland cement (PC) and mineral trioxide aggregate (MTA) were used. The following physicochemical characteristics were examined: the radiopacity, setting time, compressive strength, porosity, wettability and pH value. The biocompatibility of the cements was assessed by crystal violet, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) and cell adhesion assays. The highest radiopacity was obtained for the ECHA + Bi2O3 mixture and MTA that were statistically significant in comparison to other materials (p lt 0.05). Both initial and final setting times... as well as compressive strengths were statistically lower for experimental cements than for PC and MTA (p lt 0.05). The lowest total porosity was observed in the ECHA + ZrO2 group when compared with the other two experimental cements (p lt 0.05), but not when compared with PC and MTA (p > 0.05). Experimental cements exhibited statistically higher contact angles of glycerol than PC and MTA (p lt 0.05). For blood plasma, a statistical difference was found only between ECHA + Bi2O3 and PC (p lt 0.05). All investigated materials had alkalization ability. Cell viability assays revealed that the extracts of tested cements did not exhibit cytotoxic effect on L929 cells. Scanning electron microscopy had shown a high degree of cell proliferation and adhesion of cells from apical papilla on experimental cements' surfaces. Novel endodontic ceramics with nano-hydroxyapatite addition have satisfactory biological and physicochemical properties when compared to MTA and PC controls. Considerable lower setting time of experimental cements might present a huge advantage of these synthesized materials in clinical practice. SrF2 presents a novel promising radiopacifying agent for dental cements manufacturing.
