Abstract:
This study evaluated the design, surface finish, alloy composition, and bending strength of three ultrasonic tips-Ultra X Silver, Gold, and Blue-used for irrigant activation. Using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and bending strength tests, 30 ultrasonic tips were analysed. SEM revealed a flat, non-active tip design for all tips, with Ultra X Silver having the smoothest surface and Ultra X Gold the most irregular. EDS showed that Ultra X Silver was made of a titanium-aluminium alloy, while Ultra X Gold and Ultra X Blue were stainless steel. In bending strength tests, Ultra X Silver demonstrated the highest flexibility (315.3 gf), while Ultra X Gold had the lowest (474.5 gf). Statistical analysis showed significant differences (p < 0.05) in flexibility, surface characteristics, and composition. Ultra X Silver's smoother surface and titanium alloy enhance flexibility, ideal for curved canals, whereas Ultra X Gold offers durability but less flexibility.
