Nickel-Titanium (NiTi) files have revolutionized endodontic procedures, offering flexibility, durability, and efficiency in root canal shaping. NiTi files exhibit superior elasticity, allowing them to navigate curved canals with minimal risk of ledging, transportation, or file separation. They are available in both rotary and reciprocating systems, NiTi files provide precise shaping while preserving tooth structure. Their high fatigue resistance reduces the likelihood of breakage, ensuring safer and more predictable outcomes. Rotary NiTi files operate smoothly at controlled speeds, minimizing patient discomfort and chair time. Reciprocating NiTi files use a back-and-forth motion, reducing torsional stress and enhancing file longevity. Proper irrigation, lubrication, and torque control are essential when using NiTi files to maximize performance and safety.
