Protaper Universal Retreatment Files

ProTaper Universal retreatment files are designed to be used in sequence to remove filling materials, such as gutta-percha, carrier-based obturator, 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.

Key Specifications:

• To remove filling material before canal re-shaping
• D1 – cutting tip to facilitate initial penetration
• D2 and D3 – non-cutting tips
• D2 and D3 – to remove material from mid and apical thirds
