Brush&Bond® and Absolute Dentin™
A 2-part system for predictable and successful restorations
To ensure optimal results when placing a post and core, it is imperative to be certain that the materials being used are compatible. As clinicians, we sometimes have a propensity for mixing and matching different manufacturers’ products because we have become familiar with them and their use. However, for some procedures, it may be advantageous to stick with a particular system from one manufacturer because the components have been scientifically engineered to work together. The results may often prove to be not only successful, but predictable as well.
Studies have shown that some of the one-step, self-etching adhesives exhibit limitations when used in conjunction with self-curing or dual-curing composite materials. The limitations are due to an acid/base incompatibility with the dual-cure component.
Brush&Bond® self-etching dentin/enamel adhesive (Parkell, Inc., www.parkell.com) and Absolute Dentin™ dual-cure composite core material (Parkell, Inc.) have shown to be one system that is clinically and scientifically proven compatible for post and core placement and other restorative procedures. The activator brushes (included in the Brush&Bond kit), are used in conjunction with the Brush&Bond liquid. Using the brushes with the liquid allows the adhesive to be a dual-cure system. Because the initial pH of Brush&Bond is 2.2 to 2.3, the reaction between the calcium in the dentin and the acid monomer in the adhesive produces a virtually neutral pH. The lack of acidity allows the self-cure activator in the Absolute Dentin to polymerize without an issue. The Brush&Bond and Absolute Dentin system is ideal for post and core cementation and build-up. The result is a compatible, durable bond between the dual-cure core composite and the enamel/dentin adhesive.
Brush&Bond is also a reliable desensitizer because it permanently seals dentin tubules to prevent post-op sensitivity. Additionally, it guards the pulp against pathogens that could penetrate leaking margins.
I’ve used Brush&Bond for years, not only as an adhesive, but as an effective desensitizer as well. The combination with Absolute Dentin is just one more clinical advantage for optimizing restorative dentistry.
