Marginal microleakage and modified microtensile bond strength of Activa Bioactive, in comparison with conventional restorative materials

Abstract

Activa Bioactive without a bonding agent showed significantly lower µTBS to dentin, and higher microleakage at the enamel and dentin margins. Application of adhesive resin with Activa Bioactive provided a dentine bond strength and marginal seal comparable to other restorative materials.
