Tools of the trade: ViscoStat Clear

As I do a lot of indirect restorations where I’m replacing deep, large fillings, control of haemorrhage is crucial in being able to take an accurate scan or impression. I soak retraction cord in ViscoStat to stop bleeding from the gums. It is very helpful as often the margins are subgingival or very close to the gingiva.

What’s good about it

To get good impressions and scans, I need to effectively control bleeding. I’ve used other products in the past but nothing works as well as ViscoStat. I’ve had situations where there’s blood everywhere and then I pack in some ViscoStat soaked retraction cord and there is not a skerrick of bleeding. 

The other way I use it is when there’s a papilla that’s bleeding where it’s not actually in the sulcus. I soak a piece of gauze pellet and apply it. It works very well but, by far, its major use is when I’m trying to get a clear field of view or a dry field for an impression or a scan.

I’ve also used gingival retraction paste. While it will stop bleeding when you take an impression, any further trauma to the gingiva, like microabrasion prior to cementation, will result in bleeding again. And then, you can’t cement.

I also like that ViscoStat Clear which is, well, clear. It’s easy to accurately apply and the blood doesn’t clot into little lumps. Once you are finished you can just wash it off.

What’s not so good

Patients were so negative about the taste that I tasted it myself. It’s horrible and a bit of a weird sensation. Like fresh Szechuan pepper, it makes the tongue go numb. I give my patients a big warning before I use it with them.
