The fine folks over at J. Morita make more than the Root ZX apex locator we know and love. They have been producing some very nice consumable products recently as well. I had a chance to demo their provisional cement, PowerTemp and I have nothing but good things to say about it. Provisional cement is one of those things that you never think about until you have a problem. There are lots of different options on the market. For me, there are certain hall marks I am looking for in a provisional cement. Those hallmarks are:
1- The dispensing system should be easy. I hate having to mix things. Syringe-mixed provisional cement is easy, neat and quick.
2- It needs to be non-eugenol. I use strictly resin cements. Eugenol based provisional cements can interfere with the set of of resin or resin modified glass ionomer cements.
3- It needs to hold tightly. I hate having to waste time with recementing provisionals.
4- It needs to hold tightly but come off when I want it to. I also hate having to cut of provisionals because I can’t remove them.
PowerTemp passed all these tests with flying colors. It is easy and neat to dispense and load a provisional crown. It sets relatively quickly and cleans up easily as well. In every case we have used it, no provisional has came loose. I also never had to cut a provisional off. PowerTemp is non-eugenol so there is no chemical inhibition of resin curing. Like most provisional cements there were some areas of the preparation where the PowerTemp was a bit difficult to remove. This was mainly on resin buildup materials. I used a cotton pellet with chlorhexidine to get those areas clean.
PowerTemp is competitively priced with other provisional cements. I would highly recommend it if you are looking for a provisional cement that is easy to use and does it’s job well.
