ProFile 45/.04, 25 mm: the apical end of the crown-down

A NiTi rotary file for the crown-down technique. Dentsply Sirona use the .04 files for the terminal (apical) part of the canal; this one is an ISO 45 tip on a constant .04 taper (4%).

›  Where it sits. Apical enlargement beyond the standard sequences – the brochure’s “and larger .04 ProFile if necessary”.
›  Safe design, in Dentsply Sirona’s words. A U-shaped flute with radial lands, and a non-cutting tip that “functions as a guide allowing penetration with a minimum pressure”.
›  How it is run. Constant speed between 150 and 350 rpm, a constant in-and-out movement and light apical pressure, never forced – ideally on a motor with both speed and torque control.

Working length is taken with an ISO 010–015 hand file before the apical files go to length; irrigate abundantly and often throughout, as the directions put it. They carry one warning worth passing on: ProFile contains nickel and should not be used where there is a known nickel allergy.

What we get asked

Which files do I need for a whole case?
The brochure sets out a sequence for small, medium and large canals: Orifice Shapers first, then the .06 and .04 files crown-down, then the .04 files at working length. It is in the download below.

How do I tell the tapers apart?
By the rings on the shank: one ring on the .04 files, two on the .06, three on the Orifice Shapers.
