Resin coating should always be included in the conversation with immediate dentin sealing, but it isn’t. Immediate dentin sealing can increase bond strengths by 400%, but resin coating functions at the opposite end of the adhesive equation by reducing polymerization stress to the hybrid layer.

Dr. Alleman discusses materials used in resin coating — flowable composites — their history, uses and how to use them effectively when establishing your hybrid layer. Once again, it all comes back to decoupling with time.
