Introduction: This study aimed to evaluate and compare the apical sealing ability of different irrigation regimens (NaOCl, CHX, NS, and MTAD) . Methods: Seventy intact extracted single-rooted human teeth were selected. The roots were resected at 3 mm short of the apical foramen after access preparation. The canals were prepared with profile. This rotary file moved forward into the apical for...

Purpose This study aimed to examine novel techniques using prototype endodontic obturators obturate a resin-based sealer. Methods Powder-liquid ratios of MetaSEAL Soft were changed obtain suitable root canal sealing, and the physical properties for various powder-liquid analyzed according ISO-6876. Tensile bond strength was also examined. Prototype with combination thread numbers pitch angles s...

Abstract Magnetic fluids are the suspensions composed of magnetic nanoparticles, surfactants, and non-magnetic carrier liquids. widely used in various fields, especially sealing, because their excellent features, including rapid response, flexible flow ability, tunable magneto-viscous effect, reliable self-repairing capability. Here, we provide an in-depth, comprehensive insight into theoretica...
