ACTIVA is the first dental restorative with a bioactive resin matrix, a shock-absorbing resin component and bioactive fillers that deliver long-term benefits to your patients. ACTIVA is a “smart” material that reacts to pH changes in the mouth and actively participates with teeth and saliva in the dynamic exchange of calcium, phosphate and fluoride ions. ACTIVA chemically bonds to help seal teeth against bacterial leakage, does not cause sensitivity problems, and is ideal for multiple indications, including Class I, II, III and V restorations and bulk filling. In short, ACTIVA is the bioactive restorative and base/liner material you've been looking for.   ( disclaimer )
