#55 x 21mm Pac-File NiTi Rotary File with 0.04 Taper – 6/Pack (FNT210455)

• A nickel-titanium (NiTi) rotary file specifically designed for high-precision root canal shaping in endodontic procedures, featuring a #55 tip size, a .04 taper, and a 21mm length

• Comparable to K3, Vortex, HyFlexNT, Endosequence

Uses

• Large Canal Shaping:

• Ideal for the final preparation of wide canals, such as those found in maxillary central incisors or palatal roots

• Apical Finishing:

• Used to create a clean, larger apical seat to ensure proper irrigation and obturation

• Retreatment:

• Effective for removing larger volumes of old gutta-percha or sealer during secondary root canal procedures

• Universal Handpiece Integration:

• Operates reliably across all common rotary endodontic techniques designed for constant-taper sequences

Features

• #55 Tip Diameter:

• A larger tip size for significant mechanical debridement of infected dentin

• American-Made NiTi:

• Constructed from premium, super-elastic nickel-titanium for high flexibility despite the larger size

• Visual Safety Signal:

• The file is designed to unwind before it breaks, giving the clinician a visual warning to stop and replace the file

• Constant .04 Taper:

• Provides a predictable, narrow taper that preserves more natural tooth structure than .06 taper files

• Calibration Markings:

• Includes laser-etched rings for precise depth control within the 21mm length

• Industry Compatibility:

• Comparable in function to systems like K3, Vortex, HyFlex NT, and Endosequence

Benefits

• Extreme Fatigue Resistance:

• Offers 490% more resistance to cyclical fatigue compared to standard NiTi files, crucial for larger diameters which are typically stiffer

• Preserves Canal Anatomy:

• Despite its size, it stays centered in the canal to prevent ledge formation or apical transportation

• Cutting Efficiency:

• The three-flute design ensures rapid debris removal, reducing the time the patient spends in the chair

• Cost-Effective:

• High durability allows for more efficient use without sacrificing the safety of the procedure

• Direct System Compatibility:

• Serves as a seamless clinical alternative to market-leading file sequences like K3, Vortex, HyFlexNT, and Endosequence without needing adjustments to pre-set motor settings
