Yoshi Terauchi broken file removal kit for endodontic retreatment
The TFRK Yoshi Terauchi Broken File Removal Kit is designed for clinicians carrying out complex endodontic retreatment, separated instrument management and broken file removal.
Broken file removal is one of the most technically demanding procedures in endodontics. Success depends on visibility, magnification, ultrasonic control, conservative dentine removal, straight-line access, careful staging and the ability to engage the fractured instrument without unnecessarily weakening the root.
The TFRK system brings together the key instruments needed for this workflow, including ultrasonic broken file removal tips, a micro-explorer, micro-trephine, modified Gates Glidden, K-Endo rotary instrument, Yoshi Loop and polishing accessory.
Toothsaver clinician view
Broken file removal is not simply about pulling out a fragment. A clinical judgement needs to be made to assess whether removal is actually necessary. Bypassing may be the more conservative option, but in some cases a removal attempt is required. Successful removal depends on controlled access, conservative staging, visualisation, ultrasonic troughing and safe engagement of the separated instrument. The TFRK kit is useful because it combines the small instruments needed for each stage of the retrieval process.
Why dentists use the TFRK broken file removal kit
Designed to support the full broken file removal workflow from exploration to ultrasonic exposure and loop retrieval.
Useful in endodontic retreatment cases where rotary or hand instruments have separated inside the canal.
Micro-instruments support controlled dentine removal and careful work around the fractured file.
Available with Woodpecker/E compatible or DTE/S/N compatible ultrasonic broken file removal tips.
The Yoshi Loop helps engage a fragment when ultrasonic loosening alone is not enough.
Includes instruments for gutta percha removal, exploration, trephination, polishing and staging.
Designed for complex endodontic retrieval cases
The TFRK kit is intended for endodontic cases where a separated file or obstructing instrument must be accessed, exposed, loosened and retrieved as conservatively as possible.
In many cases, removal requires a staged approach. The clinician may need to remove coronal obstructions, refine access, expose the coronal aspect of the fragment, create controlled space around the instrument, use ultrasonics to loosen it, and then engage it with a loop system when appropriate.
For microscope-led endodontics
Broken file removal should ideally be carried out with magnification, excellent illumination, careful case selection and a conservative technique. The TFRK kit is designed for clinicians carrying out this type of microscope-led endodontic retreatment.
What is included in the TFRK kit?
The TFRK Yoshi Terauchi Broken File Removal Kit includes the instruments needed for exploration, access refinement, file exposure, ultrasonic activation, loop retrieval and finishing.
Gutta Percha Removal Instrument
TFRK-GPR hand instrument for retreatment access and gutta percha removal.
Micro-Explorer
TFRK-ME micro-explorer for locating, exploring and assessing the fragment or obstruction.
Micro-Trephine Bur
TFRK-MT micro-trephine for controlled access around the separated instrument.
Modified Gates Glidden #3
Modified Gates Glidden #3 for staging and coronal preparation during retrieval workflows.
K-Endo Rotary Instrument
Martensitic-phased NiTi rotary instrument designed for endodontic retrieval workflows.
Yoshi Loop
TFRK-L loop retrieval instrument for engaging and removing separated file fragments.
Brownie Polishing Point
Polishing accessory for smoothing or finishing during the retrieval process.
Broken File Removal Tips
Supplied with compatible ultrasonic tips depending on the selected kit variant.
Ultrasonic tip compatibility options
The TFRK kit is available in variants depending on the ultrasonic system used in your practice.

Clinical applications
The TFRK Yoshi Terauchi Broken File Removal Kit is suitable for endodontic retreatment and advanced root canal cases involving:
- Separated rotary file removal
- Broken hand file removal
- Obstructed canals
- Endodontic retreatment
- Ultrasonic exposure of separated instruments
- Loop retrieval of loosened fragments
- Conservative dentine removal around fractured instruments
- Microscope-led endodontic procedures
Broken file removal: key clinical considerations
Separated instrument removal requires careful case selection. The location of the fragment, canal curvature, remaining dentine thickness, visibility, available coronal access and clinician experience all influence whether removal is appropriate.
In some cases, bypassing the instrument may be more conservative than removal. In other cases, removal may be preferred if the fragment blocks cleaning, shaping or irrigation of infected canal anatomy.
The TFRK system is designed to support removal when the clinician has assessed that retrieval is appropriate and achievable.
Clinical safety note
Broken file removal should be performed by appropriately trained clinicians using magnification, irrigation, careful ultrasonic control and conservative dentine removal. Excessive dentine removal can weaken the root and increase procedural risk.

What is the TFRK Yoshi Terauchi kit?
The TFRK Yoshi Terauchi kit is a specialist endodontic broken file removal and instrument retrieval system designed for separated instrument cases and complex retreatment.
What does TFRK stand for?
TFRK is commonly used to refer to the Terauchi File Retrieval Kit / Terauchi File Removal Kit system for broken file removal.
What is the kit used for?
It is used for endodontic retreatment cases where a separated instrument, broken file or obstruction needs to be accessed, exposed, loosened and retrieved.
Which ultrasonic tip version should I choose?
Choose the Woodpecker/E compatible version for Woodpecker or EMS-compatible ultrasonic systems. Choose the DTE/S/N compatible version for DTE, Satelec or NSK-compatible ultrasonic systems.
Are replacement loop wires available?
Yes. Replacement loop wires are available in 0.8 mm and 1.2 mm options.
Can I buy parts separately?
Yes. Toothsaver lists multiple replacement components, including loop wires, micro trephine, K-Endo, micro explorer, gutta percha removal instrument, Yoshi Loop and polishing rod/brownie.
Does the kit remove every broken file?
No kit can guarantee removal of every separated instrument. Success depends on case selection, canal anatomy, fragment position, visibility, access, clinician experience and the amount of dentine that can be safely removed.
Should broken files always be removed?
Not always. In some cases, bypassing the fragment may be safer and more conservative. The decision depends on the clinical situation and should be made by the treating clinician.
Is magnification recommended?
Yes. Broken file removal is best carried out with magnification and excellent illumination, ideally using a dental operating microscope.
Is this suitable for general dentists?
It is suitable for clinicians with appropriate training and experience in endodontic retreatment and separated instrument management. Less experienced clinicians should seek training before attempting complex broken file removal cases.
