EndoREZ®

3. Remove cap from TwoSpense ® 2 syringe. Express a small amount on pad to verify uniform flow of base and catalyst (Fig. 1).
Confirm the presence of the mixer inside the Ultra-Mixer mixing tip. Attach Ultra-Mixer tip to the TwoSpense 2 syringe.
Express a few millimeters of “mixed” material onto mixing pad before filling into the Skini syringe to assure that mixed
material is flowing.
4. Attach appropriate length NaviTip to Skini syringe. Ensure tip is firmly attached to prevent tip loss during sealer/filler
placement.
5. Insert Ultra-Mixer tip into back end of Skini syringe. Dispense desired quantity of material in back end or front end of syringe
(Fig. 2). Insert plunger and press down until air is out of syringe and material is flowing from NaviTip. Express a small amount
on pad. Note quantity that flows from NaviTip in a few seconds, this gives an idea of how long it takes to fill the canal.
Important note: Make sure canal has been cleaned and shaped before inserting NaviTip with EndoREZ into canal. This is
necessary for quality root canal treatment, but it is also important to prevent dentin debris etc. from jamming with EndoREZ
into tip end and preventing flow from tip.
6. Insert NaviTip into canal to within 2-3mm of apex or short of snug fit within canal (Fig. 3). Do not deliver into
canal if a tight fit is noted. Doing so may express excessive EndoREZ beyond apex (see precaution #5). If you don’t
see EndoREZ flowing up canal around NaviTip, stop delivering and ensure tip is not clogged or ensure material is not
being expressed past the apex. Do not use force to push EndoREZ plunger to express material as you might push
material past apex. Do not use plastic tips or Capillary tips to deliver EndoREZ into canal.
7. Withdraw Skini syringe slowly while delivering sealer into canal space. Filling canal space to pulpal floor will provide
adequate sealer to obturate canal.
8. Insert pre-fit master cone into place. Avoid multiple placements and pumping action to minimize risk of expressing
EndoREZ beyond apex (see precaution #5). Note: For large canals insert extra gutta percha cones to minimize large
masses of EndoREZ; simply “harpoon” in as lateral condensation is not necessary.
9. Trim excess gutta percha at canal orifice with hot instrument. EndoREZ will begin to set in 7 to 8 minutes, and will be firm
set in canal in 15 to 20 minutes (body temperature).
10. Mixing tip should be left onTwoSpense 2 syringe between patients.
11. It is normal for EndoREZ to not completely set in the one to three millimeters immediately adjacent to provisional filling
materials. It has long been known that eugenol and eugenol-like chemistries inhibit the set of most all dental resins (one to
three millimeters deep potentially). To facilitate immediate definitive bonded restoration placement and to minimize or prevent
surface inhibition under provisionals, a small quanitiy of Ultra-Blend ® plus or a flowable composite can be delivered via a
Black Micro ® tip to the just placed EnodREZ at the canal orifice and light cured.
Pad mixing and syringe delivery:
To mix EndoREZ, remove cap from the TwoSpense 2 syringe and express material directly onto mixing pad and mix with spatula
as usual. Backload material into small skini syringe with spatula. Deliver mixed EndoREZ to canals with NaviTip attached per
steps 5 thru 7 above. Place gutta percha, etc. as per steps 8 onward.
Note: As with other resins, oxygen inhibition will greatly affect or prevent setting of mixed EndoREZ on the open mixing pad.
Posts:
Begin post preparation with number 2-4 Gates Glidden Drill first, followed by post preparation drills of choice. EndoREZ is easily
drilled out for placement of posts. We recommend microabraded titanium or bondable resin/fiber PermaPosts cemented with
PermaFlo ® DC dentin adhesive and dual cure resin luting system.
