Rotary files are generally preferred for removing fillings from canal walls because retreatment with hand files
can be a tedious, time-consuming process.
Root canal transportation with a Ni-Ti rotary file system and stainless steel hand files
in simulated root canals.
In such a case, the instrumentation with the F2 would be carried to a level coronal to the curvature; the preparation of the apical part would then be completed with hand files
Effectiveness of two nickel-titanium rotary instruments and a hand file
for removing gutta-percha in severely curved root canals during retreatment: an ex vivo study.
Can you visualize the contours, hand file
it from the proper metal, and harden it if required?
We recommend that you sharpen it with a hand file
Then I would see the tool room technicians hand file
The root canals were prepared following an endodontic hand file
technique using a Flexofile K file.
To get the slide configuration that I wanted, it took several hours with a hand file
, followed by a belt sander and hand sanding to re-contour the slide.
In most cases the technique only requires one hand file
followed by one single WaveOneTM file to completely shape the canal.
It would be impossible to etch checkering like this with a hand file
because the area you'd want to checker is surrounded by stuff you just don't want to cut.
They found that rotary and ultrasonic techniques removed significantly more residues than the hand file
and irrigating solution techniques.
