The reality is, all details matter and the oral environment must be kept meticulous to have restorations that are well placed. Unfortunately, many of the materials we use in dentistry are not forgiving to the harsh oral environment, especially when they are exposed to blood and saliva.
A properly controlled field is of paramount importance when we are taking either a conventional impression using a vinyl-polysiloxane (VPS) or a digital impression. VPS materials are hydrophobic in nature and do not set well when exposed to blood or saliva. Digital technologies have improved drastically; however, they cannot scan through blood or saliva.
To get the field under control, I use a hemostatic agent with a proper delivery system. While there are many products that claim to do an effective job with hemostasis, my go to product for nearly 20 years has been ViscoStat from Ultradent Products.
ViscoSat is a 20% ferric sulfate that stops bleeding in a few seconds when scrubbed onto the bleeding site. When it is used in conjunction with the Dento-Infusor tip and scrubbed into the sulcus, it also stops crevicular fluid, which is equally important. It does this while being relatively kind to the tissue because it uses a patented fumed silica to control the acidity. An additional benefit is the material allows it to stay in place until it is rinsed away.
This single product has allowed me to perform more predictable dentistry than almost anything else we use in our practice. I’m able to capture impressions time and time again on the first attempt when I use this product with a dual cord technique, allowing for predictable adhesive dentistry on a daily basis.
