bi-directional spiral & epoxy root canal cement
Patented Design:
1.
Instrument the canal to an apical size of 30-35 or larger and
produce a smoothly tapered canal space. Remove the smear
layer with 17% EDTA (EDTA Plus, Cat. No. 770-16). EDS rec-
ommends the use of Endo-CHX (2% Chlorhexidine, Cat. No.
750-16) to cleanse the root canal.
2.
Fit the master gutta percha point (We recommend the use of
EDS' Medium Gutta Percha Points. Cat. No 5000-M for the
SafeSider Technique) and verify that it goes to working length.
It may be necessary to trim the apical portion in order to obtain
the snug apical fit indicated by 'tug-back.' This process is
depicted in figures 1, 2, and 3.

3.
Place the bi-directional spiral in a low-speed handpiece set
to run at approximately 1,000 RPM. Ensure that the hand-
piece is running in the forward direction (clockwise). Adjust
the rubber stop to 3mm short of the working length. When
using the bi-directional spiral, ensure that the rubber stop does
not hit the tooth, shift position, and become an inaccurate
guide. (To avoid the rubber stop shifting use SafeSider Endo
Stops Cat. No. 5000-06).
4.
Remove the cap on the EZ-Fill Xpress syringe and attach the
mixing tip as depicted in Figures 4, 5, and 6. Depress the
plunger to express material onto the mixing pad. Discard the
first few drops of sealer as they may be improperly mixed.

5.
Dry the canal with paper points.

Coat the bi-directional spiral with
thick layer of cement (Fig 7) and place
into the canal. Run the spiral at 1,000
RPM for approximately 5 seconds using
a slow, circular up and
down motion of at
least
7-8
stokes
depicted in figures 8,
9, and 10. Use the bi-
directional
spiral
3mm short of length.
If the canal is severe-
ly curved, only take
the bi-directional spi-
ral to the point of
curvature.
The bi-
directional spiral will
force the cement later-
ally coating the walls
and filling any acces-
sory canals.
Note: If a you wish
to thin EZ-Fill you
may heat it with
a warm (not hot) metal spatula.
7.
Repeat step 5 once more
(twice for exceptionally large
canals). Excess cement will exit
coronally, but very little
cement will go beyond the
apex.
8.
Coat the apical 10-12
mms of the prefitted gutta
percha point liberally with
cement and insert point into
the canal.
Excess coronal
gutta
percha
can
removed by searing with a
hot plugger as depicted in
figures 11-12. The cement
will harden in 2 to 3 hours.
9.
If the restoration will not
be completed during the
same visit, create a proper
temporary coronal seal.
10.
If a post-hole is desired
immediately, use a #3 peeso reamer to remove the gutta per-
cha to the depth desired. For maximum post retention and sta-
bility it is recommended that either Flexi-Post or Flexi-Flange
(Essential Dental Systems) be used.
Note: If a you wish to thin EZ-Fill you may heat it with a
warm (not hot) metal spatula.
If material is hard to express, you may run the syringe
under warm water.
Contraindications: Individuals with allergies to epoxy resins,
polyamide resins, or any other component of the root canal
filling material.
