Description:

The X7400425RF EDGEFILE X7 .04 #40 25MM is a state-of-the-art rotary endodontic file that delivers outstanding performance, control, and safety during root canal shaping, particularly in medium-length canals needing larger apical preparation. As part of the cutting-edge EDGEFILE X7 series, this file is made from FireWire™ heat-treated nickel-titanium (NiTi) alloy, which is renowned for its exceptional flexibility, controlled memory, and remarkable resistance to cyclic fatigue. These material properties significantly reduce the likelihood of file separation and enable the instrument to adapt closely to the canal's natural curvature, promoting safer and more predictable treatment results. With a #40 tip size, .04 taper, and a 25mm working length, this file is optimally designed for use in premolars and molars where proper apical enlargement is crucial for effective cleaning and obturation. The moderate .04 taper allows for conservative removal of dentin, preserving the structural integrity of the tooth while providing sufficient space for irrigation and filling materials. The file features a non-landed, square cross-section that offers both aggressive yet controlled cutting efficiency, minimizing contact with canal walls and reducing torsional stress. This design encourages smooth file progression and efficient debris removal, helping to prevent common issues like ledging, canal blockage, or transportation. Dentists benefit from improved tactile feedback and seamless instrument navigation, which enhances precision and lessens operator fatigue during procedures. The file’s durable cutting performance and resistance to cyclic fatigue also contribute to reduced chair time and increased patient comfort. Compatible with most rotary endodontic motors, the X7400425RF EDGEFILE X7 integrates effortlessly into a range of clinical practices. Suitable for both general dentists and specialized endodontists, it provides consistent, reliable, and efficient shaping outcomes, thereby supporting optimal root canal therapy results and superior endodontic care.
