assorted sizes
Features and Benefits:
ProTaper Retreament Files are designed to be used in sequence to
remove filling materials, such as gutta-percha, carrier-based
obturators and paste fillers. The three, easily identified files
are designed for the different needs of unfilling the coronal
third, the mid-third and the apical third - before canal reshaping.
A working tip on the D1 file facilitates initial penetration. Each
handle is no more than 11 mm for better visibility.
D1: for the removal of material from the canal1/3.
D2: for the removal of material from the middle 1/3.
D3: for the removal of material from the apcial 1/3.
Use Protocol :
When the rotary removal method is utilized, select the lowest speed
(250-300 rpm) that will effectively engage and remove obturation
material from the canal.
1) Flood the pulp chamber with the appropriate solvent and probe
the canal orifice with an explorer to check if the paste has been
effectively softened.
2) Without engaging dentin, gently press the spinning D1 File into
the material and use a short pecking motion to extract material out
of the canal. Never engage D1 around a canal curvature.
3) Remove the D1 File frequently, inspect the blades for obturation
material and clean the debris from the flutes.
4) Continue with the D1 File, until paste is removed from the
coronal one-third of the canal.
5) Select the D2 File and repeat the same pecking action to extract
obturation material from the middle one-third of the canal. Use a
brushing outstroke motion to remove material from the canal walls.
6) When appropriate, choose the D3 File and, in the same way auger
the more deeply positioned paste material out of the apical
one-third of the canal.
7) Continue with the D3 File as long as the flutes of the
instrument, upon removal, are loaded with obturation material.
8) When the obturation material is short of the canal terminus, use
small sized hand files in the presence of a viscous chelator to
negotiate and secure the rest of the canal.
9) After assessing the glide path, select either manual or rotary
NiTi MTF Files to shape and finish the canal.
