Series of patented, non-circular, non-interrupted flat-sided instruments designed to reduce endodontic stress. A high level of predictable performance, without fear of instrument fracture, eliminates procedural stress for dentists and their patients. In Nickle Titanium. Improved access into canal curvature. Preserves the dentin. Guarantees optimal instrument durability. Lessens risks of thread line clogging and fractures. SafeSiders are color-coded hand reamers with non-circular and flat-sided designs that allow access to curved or calcified canals. They have stainless steel or nickel-titanium composition that prevents clogging of thread lines, breakage, or fracture, minimizing tensile and compressive stress for enhanced file durability.SafeSiders lower the risk of ledging, perforation, and transportation while conserving the dentin.
