Waldent Seal Pex powder and resin combine to create a root canal filling material with outstanding sealing capability. Due to its precise adaptation to root canal walls and minimal contraction during setting, Seal Pex enables a tight and excellent tissue-compatible obturation. Waldent Seal Pex meets the standards of ISO 6876:1986 (e) for dental root canal filling materials.
Indications:
- Permanent obturation of root canals of teeth of the secondary dentition .
Features
- Resin-based, non-acrylic, eugenol-free sealer.
- Excellent radiopacity.
- Working time 4-6 hours – means no waste of material on pad
- Setting time 9-15 hours – allows for corrections of fillings
- Suitable for all obturation techniques.
- Outstanding dimensional stability and low solubility for a durable, safe seal
- Outstanding flow characteristics to flow into and seal lateral canals
- Silver-free for no discoloration of teeth
- Thermoplastic ability makes it easy to remove
- Compatible with any filling technique.
Composition:-
- Seal Pex Powder: Bismuth oxide, Methenamine, /Titanium dioxide
- Seal Pex Resin: Epoxy Resin
Storage:-
- Store at room temperature.
- Keep the powder bottle and resin tube tightly closed.
Setting time:-
- The setting time according ISO 6876 : 1986 (e) ranges between 9 and 15 hours at 37 °c.
Packaging
- 1 x Powder 10g
- 1 x Liquid 10ml
Driection to Use:
Dosage and mixing:-
- Powder and liquid are mixed on a glass slab using a metal spatula.
- 2 to 3 volume units of powder are mixed with 1 volume unit of resin.
- Mix to a homogeneous consistency which breaks when lifted 1.5 to 2.5 cm (1/2 to 1 inch) above the glass slab.
- If a particularly fluid mix is required, the glass slab with the cement mixture may be carefully warmed over an alcohol flame.
Step-by-step instructions:-
- Apply the mixed cement onto the tip of a lentulo spiral.To avoid the formation of air bubbles in the material and overfilling of the canal, advance the lentulo spiral slowly to the apex running at very low speed.
- Withdraw lentulo very slowly, still running at low speed.
- If seal-pex is used in combination with gutta percha points or other cores and if there is the risk of overfilling, use reamers to apply seal pex into the canal.
- Choose a reamer of the size of the last instrument used during apical root canal preparation.
- Place seal pex by a pumping action of the reamer with simultaneous rotary movement in a counter clock direction.
- It is only necessary to apply a light coating of seal-pex.
- Dip the disinfected and dry master point into seal pex and with pumping motions slowly push it into the canals.
- Additional gutta percha points and lateral or vertical condensation methods can be applied.
