When I mixed the MetaSEAL, the resulting mix was too runny for my liking.  Is it possible to adjust the powder/liquid ratio so that the resulting sealer is thicker?

Yes.  The MetaSEAL viscosity can be adjusted by using between two and three drops of liquid to each scoop of powder.




What is the best method to place the MetaSEAL into the canal?

The recommended method for placing MetaSEAL in a canal is:

1)    After final water irrigation and paper point drying,

a)            Work it into the canal using endodontic hand files, or…

b)            Coat a gutta percha point with MetaSEAL and pump it into the canal with both rotational and up and down motions, and then…

2)    Coat the master point (gutta percha or Resilon®) with MetaSEAL and pump it into the canal with both rotational and up and down motions.  This is then followed by final seating to measurement of the master cone.




Can I use Parkell’s Thermique (or other thermal condensing devices) with MetaSEAL?

No.  Never use a separate hot instrument or a device that introduces heat into a canal which contains MetaSEAL.  Heat will cause the MetaSEAL to quick set in the canal thereby preventing further access to it, and possibly even locking the heated instrument in the prematurely set MetaSEAL.





The MetaSEAL does not seem to harden more than about 1mm when I light cure it.  Is this normal?

Yes.  When you hit the coronal access opening with your curing light, the MetaSEAL will form a light-cured surface scab. This scab acts to seal the canal by preventing leakage during the critical provisional period between the completion of the root canal and the initiation of restorative treatment.




What is the working time for MetaSEAL?

The working time is approximately 30 minutes when spread out thin on a mixing pad.  If you let it sit on the pad for more than 30 minutes, it will no longer set if placed in the canal.
