Dentsply Protaper Universal Retreatment Rotary Files

Dark grey handles no more than 11mm long for better visibility.
One, two or three white bands according to the instrument selected.
3 lengths, 3 progressive tapers and 3 apical diameters to remove materials from coronal, middle and apical thirds of root canals.
The D1 has a working tip to facilitate initial penetration.
ProTaper Universal retreatment 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 has a cutting tip to facilitate initial penetration into the filling material. D2 and D3 both have non-cutting tips and are used to remove material from the mid and apical thirds, respectively.
