Ivoclar Vivadent Apexit Plus - Manual (Page 2)

Contraindication
– Retrograde obturation
– Do not use Apexit Plus in patients with a known allergy
to any of the product’s ingredients.
Side Effects
Avoid contact of Apexit Plus with the skin / mucous
membranes and the eyes. Unset Apexit Plus may cause
slight irritations.
Interactions
The setting time of Apexit Plus in the root canal is dependent
upon the availability of moisture. The setting reaction
can progress very quickly in canals which have been
inadequately dried. The amount of moisture required for
the setting reaction reaches the root canal by means of the
dentinal tubules. The material begins to set at the apex, as
dentin is thinnest in this region and the apical foramen
admits additional moisture. Thus even when using Apexit
Plus, make sure to thoroughly dry the root canal system
prior to performing the obturation. Outside the mouth, on
the mixing pad, Apexit Plus may remain soft for several
days, depending on the ambient humidity.
Application
Remove the cap of the double-push syringe by turning it
1/4 turn counter clock-wise (discard the cap, do not re-use
it!) and replace it with a mixing tip. If the double-push
syringe has been used before, replace the used mixing tip
with a new one just before dispensing Apexit Plus. Insert
the mixing tip. Push the tip completely down until the notch
of the mixing tip is aligned with that of the double-push
syringe. Secure the mixing tip in place by gripping the
coloured base and turning it 1/4 turn clock-wise. The dou-
ble-push syringe contains pre-dosed amounts of Apexit Plus
base and activator, which are automatically mixed and dis-
pensed when the two components are extruded.
You may either pick up the mixed material directly with a
lentulo spiral filler and spin it into the canal, or introduce
the material into the canal with the Intra-Oral Root Canal
Tips, and then use the lentulo to spin it up the canal to the
apical area. Subsequently, the root canal is filled in a
conventional manner using gutta-percha points or warm
gutta-percha.
At room temperature and medium humidity, Apexit Plus
remains soft for several hours after mixing and dispensing.
This permits obturation of multiple canals with a single mix.
The setting time of Apexit Plus is between three and five
hours. In very dry canals, or in situations where the sealer
layer is thicker than usual (e.g. when the single cone tech-
nique is used), the setting time can be more than ten hours.
Further treatment steps may be performed with any suit-
able material. Further manipulation of the root canal sys-
tem, such as the insertion of an endodontic post or an
apicectomy should not be done prior to 24 hours following
root canal obturation.
Apexit Plus does not contain any pharmaceutical substances
such as corticoids, antibiotics or formalde hyde-based
preparations.
Thus apical foci of inflammation are not masked by the
antiphlogistic and immunosuppressive effect of these
additives. To avoid postoperative sensitivity in the event
of an infected canal, however, antibacterial root canal
dressings should be placed prior to applying Apexit Plus.
Should postoperative sensitivity occur, it should cease after
a maximum of 48 hours.
Storage and shelf life
– Do not use Apexit Plus after the indicated date of
expiration.
– As Apexit Plus is temperature insensitive, it may either
be stored at room temperature or in the refrigerator
(2 to 28 °C/ 36 to 83 °F).
– Leave the used mixing tip on the syringe.
Do not replace it with a new one until right before
the next use. Do not re-use the original cap!
