|The ultimate goal of the endodontic treatment is either to prevent or cure apical periodontitis. When non-surgical endodontic treatment failed to resolve apical periodontitis or unlikely to improve treatment outcome, periapical surgery was indicated. Long term success of periapical surgery is correlated with sealing efficiency of root-end filling materials because efficient sealing ability minimize egress of irritants from inside the root-canal space to the surrounding periodontium. Mineral trioxide aggregate (MTA) seem to be the gold standard material for periapical surgery. Biodentine is a tricalcium silicate bioactive dentine substitute that has similar physical and biological properties to MTA with a shorter setting time and better handling properties. The aim of this in vitro study was to compare microleakage and marginal adaptation of biodentine, white MTA (WMTA) and glass ionomer cement (GIC) as root-end filling materials using dye extraction method and scanning electron microscope (SEM), respectively. The results of dye absorbance value and interfacial gap width of the three materials were correlated to seek a correlation between microleakage and marginal adaptation of the three root-end filling materials. The results revealed that WMTA had lower dye absorbance values and smaller interfacial gap distance compared to biodentine and GIC with no statistical significant difference between them. Significant positive correlation was found between sealing ability and marginal adaptation of the tested materials. More in vitro and clinical studies are needed to evaluate biodentine as a rootend filling material.|
