Early Adopters: Core-Flo DC Lite
A low viscosity, self-leveling material with fluoride for core build-up, post cementation, and dentin replacement, CORE-FLO DC Lite is a brand extension of Bisco’s tried-and-true stackable core material, Core-Flo DC. Here, Dr. Fred H. Peck, a lecturer, author and accredited member of the American Academy of Cosmetic Dentistry, shares his chair-side experience with this product.
How did you first learn about CORE-FLO DC Lite and what made you decide to start using it?
Dr. Fred H. Peck: I talked to someone at Bisco who told me they’d be coming out with a more flowable build-up material, and I thought that would be some-thing useful. I tested it during the evaluation phase and have been using it since—for about a year.
Is this material fulfilling a specific need that existed previously?
FP: There are times when I want something more flowable. For instance, in a deep area you can end up with voids with regular viscosity material, and lower viscosity material just flows better. In the bottom of an interproximal box or when I’m doing a build-up over a completed endo, I might use the DC Lite all the way through or in combination with the regular DC. So basically, if I need flowability, that’s when I use it.
What features do you consider unique from other build-up materials?
FP: I think the flowablity sets it apart. It cuts very similar to the regular formula, so once it’s cured it’s not too soft. I also like that it’s a self-leveling material because of the flowablity; it levels itself out without having to move the material around.
Can you talk about your overall experience with the product, and whether it has had a chair-side impact or affected patient outcomes?
FP: I have a general practice and do lots of cosmetic and reconstructive cases, and it’s one of my go-to materials. Depending upon what I need, I can ask for Lite or regular, so it gives me more flexibility so I can just keep moving along during a procedure. I’ve used it to cement a few posts and cores, and it has worked fi ne. And in deep core build-ups, it flows into areas where it’s been hard to get other products to go. Also, the fact that it’s dual-cured means that I don’t have to worry about access to the light. The biggest thing is that when I’m prepping the tooth, I’m not getting voids like I would with other materials. Even with regular flow materials, I might get a void here and there that I need to go back and fill. Fewer voids make things easier.
You’ve talked about flowability and self-leveling as advantages of this material. Can you think of a specific case that illustrates the usefulness of these features?
FP: The CORE-FLO DC Lite is ideal to use in a deep preparation, such as over a root canal. The tooth structure is hard to access for both placement and light curing, because it can be deep. One advantage of CORE-FLO DC Lite is its flowability and self-leveling feature. A recent crown preparation case featured this situation where this author was confident that the material covered the gutta percha, flowed well, and left no voids on an upper first molar. After the material leveled, it was light cured to begin the complete curing process and complete the crown build-up. The crown prep was completed, a final impression was taken, and the temporary placed with the eventual placement of the all-ceramic crown.
What else do you feel practitioners should know about this product?
FP: The material works well in areas that are deep, hard to access, and hard to visualize—for example, subgingival. I feel more confident that I’ll get a good seal in those areas with this material. It also works great to block out undercuts, fill small areas of decay in a prep, and fi ll any type of void from other materials.
