The ProTaper Finishing files F1, F2, and F3 have fixed tapers of 7, 8 and 9%, respectively, in their apical extents. However, from D4-D14 they have decreasing percentage tapers even though each cross-sectional diameter gets larger over length.

What are K files?

Premier K-Files are used to enlarge canal after debridement with a reamer. After reamer, use a file one size smaller than the reamer so that the fragments of dentinal shavings can be carried away from the root-canal walls.

How do dentists use ProTaper?

Use the S1, with a brushing action, until working length is reached. Use the S2, with a brushing action, until working length is reached. Reconfirm working length, irrigate, recapitulate and re-irrigate, especially in more curved canals.

What are K files used for?

K files are the universal standard for canal negotiation, shaping, and recapitulation of root canal systems. They are generally used with a quarter turn “watch-winding” motion and vertical pull.

What is the difference between ProTaper and ProTaper gold?

ProTaper Gold was the rotary system that most respected the initial S-shaped canal anatomy. ProTaper Universal was the system that originated the greatest modification of the initial canal, presenting a significant tendency to straighten the apical curvature.
