Quick reference guide
Before using any rotary file system:
GLIDE PATH
1. Place rubber dam and prepare access cavity. The Cavity Access Set and Start-X
ultrasonic tips are recommended.
SHAPING
RECOMMENDED
During canal shaping, irrigate, recapitulate with a small-sized hand file
after each sequential PROTAPER NEXT instrument, then re-irrigate.
OPTIONAL
The EndoActivator® is recommended for use during irrigation.
2. Prepare straight line access to canal orifice. The ProTaper SX file may be used.
3. Explore the canal using small-sized hand files, determine working length, verify
patency and confirm a smooth, reproducible glide path.
4. Always irrigate and if necessary, expand the glide path using small-sized
hand files or dedicated mechanical glide path files. PathFiles P1 and P2 are
recommended.
Use PROTAPER NEXT rotary files in a constant rotation at a speed of 300 rpm with
light apical pressure.
Clean flutes of the instruments frequently and check for signs of distortion or wear.
5. In the presence of NaOCl, brush and follow the glide path, with the PROTAPER
NEXT™ X1 (017/04) file, in one or more passes until the working length is
reached.
The PROTAPER NEXT instruments are recommended to be used mechanically
(manually in very severe curvatures) in a clockwise continuous motion.
The PROTAPER NEXT instruments are recommended to be used with a brushing
motion, away from external root concavities, to facilitate flute unloading and apical
file progression.
6. Use PROTAPER NEXT X2 (025/06), exactly as described for PROTAPER NEXT X1
file, until the working length is passively reached.
7. Gauge the foramen with a size 025 hand file and, if this file binds at length, the
canal is shaped and ready for disinfection.
P1
8. If the size 025 hand file is loose at length, then continue shaping with the
PROTAPER NEXT X3 (30/07) and, when necessary, the PROTAPER NEXT X4
(040/06) or PROTAPER NEXT X5 (050/06), gauging after each instrument with
the 030, 040 or 050 hand files, respectively.

2. Select the matching GuttaCore Verifier for PROTAPER
NEXT; set the rubber stopper at working length using
the verifier’s calibration mark; and confirm a passive fit
at working length by rotating in the canal 180°. If the fit
is not passive, use the Verifier as a finishing file to gently
enlarge the canal terminus.

calibration ring on the obturator. The calibration rings are
set at the following working lengths (in millimetres): 18,
19, 20, 22, 24, plus 27 and 29 on the obturators.
7. Heat the obturator and when it is ready (oven audible
beep and flashing light), remove it from the oven. Place
the obturator smoothly, with one slow continuous motion,
into the canal to working length.
8. Remove the handle from the GuttaCore Obturator at
the orifice by bending to either side of the canal wall or
firmly hold the handle with one finger and use a sharp
endodontic spoon excavator to cut off the handle. For
posterior access, the handle may be removed prior to
insertion into the canal with tweezers.
5. Brush a very light coating of AH Plus sealer throughout
the coronal-apical canal system using a sterile
PROTAPER NEXT paper point. Then use an additional
PROTAPER NEXT paper point to remove any excess
sealer that may have accumulated on the canal walls or
pooled in the apex.

6. Place the matching GuttaCore Obturator for PROTAPER
NEXT in the ThermaPrep® 2 oven at the lowest heat
setting (20). Set the working length with the rubber
stopper by placing the stopper directly below the
Fill one canal at a time. To avoid overflow of guttapercha, place absorbent points in the unfilled canals.

OBTURATION SEQUENCE WITH
GUTTACORE FOR PROTAPER NEXT
1. Ensure the canal has been flared coronally so the
GuttaCore™ Obturator has sufficient space to enter
the root canal along the straight line access by using
an orifice shaping instrument as necessary such as
ProTaper® SX file.
