All three sizes, which is how the sequence is meant to be bought

The assorted blister holds the whole sequence – 013, 016 and 019 – in one pack of six. Dentsply Sirona designed PathFile® as a three-file progression, and this is the pack that matches how it is used.

The facts

Why this one

Buying the three sizes as singles means three part-used blisters and a running count of which one is short. The assorted pack tracks the sequence instead.

PathFile® was developed with Dr Berutti, Dr Cantatore and Dr Castellucci, and it is the range that established the idea of cutting the glide path with a dedicated rotary instrument rather than a sequence of hand files.

What the evidence says

Berutti and colleagues compared preflaring with hand K-files against PathFile® in one hundred S-shaped training blocks, with an endodontist and an inexperienced clinician each doing both. The PathFile groups showed significantly less modification of canal curvature and significantly fewer canal aberrations – and, notably, the inexperienced clinician using PathFile® produced more conservative shaping than the expert using manual preflaring. (Berutti E et al., Journal of Endodontics 2009 – simulated canals in training blocks, not teeth. Berutti co-developed the instrument.)

A later independent study went to extracted teeth. Zheng and colleagues scanned sixty mesial canals of mandibular first molars by micro-CT and found PathFile® transported the canal significantly less than hand K-files at every level measured, and extruded less debris apically. (Zheng L et al., BMC Oral Health 2018 – ex vivo, micro-computed tomography.)

Questions we get asked

What is in the pack?
Six files covering the three sizes – 013, 016 and 019 – all at 21 mm. To reorder one size on its own, the singles are PathFile® 013, 21 mm · PathFile® 016, 21 mm · PathFile® 019, 21 mm.

Where does it sit against the hand file?
Dentsply Sirona’s sequence has you establish working length with an ISO 008 or 010 hand file first, then take 013, 016 and 019 to length in turn, irrigating between each. The rotary files replace the larger hand files, not the scouting one.

What are the motor settings?
300 rpm, continuous rotation, with light apical pressure and the flutes cleaned frequently. Both motors we stock will run it: X-Smart® Pro+ and VDW.SILVER® RECIPROC®.

Can the files be reused?
No. They are supplied sterile for single patient use. Three files go into one canal in sequence, so the pack of six is one glide path per two canals.

Is there a one-file alternative?
Two, and we stock both. ProGlider® cuts the glide path with a single rotary file on a variable progressive taper; R-PILOT® does it in one reciprocating file on the RECIPROC ALL setting. PathFile® takes three passes and steps up in smaller increments.
