We seal and fill our canals with PCA Root Canal Sealer.
Notice the phrase 'seal and fill'. These are two separate and distinct processes.
We have emphasized for years that those who use gutta percha, mainly use it as a disposable plugger. It is used as a method of pushing the cement into the nooks and crannies of the canal space...and the left there for the sake of convenience.
If you doubt that this is true. Use this 'reductio ad absurdam'. Leave out the cement. What would happen? Leave out the gutta percha. What would happen? And then it becomes obvious that the essential part is the cement.
Even those who use molten gutta percha with a syringe(with few exceptions), use cement to fill the gaps.
We are rather proud to note that we have been teaching this since 1976. Now most of the major companies offer some sort of filling syringe and some sort of cement to fill with. Imitation, they say, is the most sincere form of flattery. We thank them. :)
Recently two companies have advertised their syringes and syringeable products in national publications.
The interesting thing is that they are all coming around to where we have been since the beginning, namely mechanical preparation with cement fills. The only difference being that most use some sort of plug and then backfilling.
We have approached the problem head on i.e. coming up with a way to fill AND seal with cement using technology to control the flow of cement instead of "corking" the apex first.
Check us out. I think that you'll agree that our method is far superior and MUCH simpler.
The simplicity comes from two angles:
