Description:

The X7450425RF EDGEFILE X7 .04 #45 25MM is a premium rotary endodontic file designed to deliver outstanding performance, control, and safety during the shaping of medium-length root canals that necessitate larger apical preparations. As part of the EDGEFILE X7 line, this file is made from FireWire™ heat-treated nickel-titanium (NiTi) alloy, recognized for its superior flexibility, controlled memory, and high resistance to cyclic fatigue. These characteristics significantly diminish the likelihood of instrument separation and facilitate the file’s adherence to the canal's natural curvature, promoting safer and more predictable instrumentation. With a #45 tip size, .04 taper, and a 25mm working length, the X7450425RF is perfectly suited for shaping premolars and molars where accurate apical enlargement is necessary. The .04 taper allows for conservative removal of dentin, preserving tooth structure while ensuring sufficient space for effective irrigation, disinfection, and obturation. This taper method supports a controlled yet efficient preparation of the canal to achieve optimum cleaning and filling. The file’s non-landed, square cross-section enhances its efficiency in cutting, which decreases the risk of excessive contact with canal walls and minimizes torsional stress. This feature promotes enhanced file progression, effective removal of debris, and reduces complications like ledging, canal blockage, or transportation. Consequently, the result is a smoother and more efficient root canal treatment. Clinicians gain from improved tactile feedback and ease of navigation when using the X7450425RF EDGEFILE X7, leading to increased precision and reduced operator fatigue during procedures. The file’s strong cutting ability, combined with its flexibility and resistance to cyclic fatigue, ensures shorter treatment times and heightened patient comfort. Fully compatible with most rotary endodontic motors, the X7450425RF fits seamlessly into diverse clinical workflows. It is suitable for both general dentists and endodontic specialists, providing predictable, efficient, and safe shaping of root canals, thereby supporting superior endodontic care and optimal therapeutic results.
