F2 Medical TF4 Endodontic Files
Product Information
The product is called To & Fro PLUS Endodontic Files (TF4) WaveOneGold
Compatible EndoFiles. These files are reciprocating, single-file system used
for endodontic procedures. They are heat-treated and made from gold NiTi
using advanced metallurgy,which enhances flexibility.
The product comes in four sizes: #20/.07 Taper, #25/.07 Taper, #35/.06
Taper, and #45/.05 Taper.
Product Usage Instructions
- Establish straight-line coronal and radicular access.
- In the presence of a viscous chelator, use a size #10 hand file to verify a glide path to length. In more restrictive canals, use asize #10 hand file in any region of a canal to create a glide path.
- Expand this glide path to at least 0.15mm using either a manual or dedicated mechanical file, such as ET Files or the dedicated TF4 File.
- Always initiate the shaping procedure with the PRIMARY file (#25/.07 Red) in the presence of sodium hypochlorite.
- Use gentle inward pressure and let the PRIMARY file passively progress through any region of the canal that has a confirmed glide path.
- After shaping 2-3mm of any given canal, remove and clean the PRIMARY file, then irrigate, recapitulate with a size #10 hand file, and re-irrigate.
- Continue with the PRIMARY file in 2-3 passes to pre-enlarge the coronal two-thirds of the canal.
- Utilize a brushing motion on the outstroke to eliminate coronal interferences or to enhance shaping results in canals that exhibit irregular cross-sections.
- In more restrictive canals, use a size #10 hand file, in the presence of a viscous chelator, negotiate to the terminus of the canal.
- Gently work this file until it is completely loose at length. Establish working length, confirm patency, and verify the glide path.
- Expand this glide path to at least 0.15mm using a manual or mechanical glide path file.
- Carry the PRIMARY file to the full working length in one or more passes.
- Upon reaching length, remove the file to avoid over-enlarging the foramen.
- Inspect the apical flutes. If they are loaded with dental debris, then the shaping is finished.
- If the PRIMARY file doesn’t progress, then use the SMALL file (#20/.07 Yellow) in one or more passes to working length and then use the PRIMARY file to working length to optimize the shape.
- When the shape is confirmed, proceed with 3-D disinfection protocols.
- If the PRIMARY file is loose at length with no dental debris inthe apical flutes, continue shaping with MEDIUM file (#35/.06 Green) and/or LARGE file (#45/.05 White) until the apical flutes are loaded.
