Owing to their adequate adhesive, esthetic, and mechanical properties resin-based cement has been widely used in dental practice to bond metallic, ceramic, or polymeric indirect restorations (crowns, veneers, inlays, onlays, or fixed partial dentures) in mineralized dental tissues. 1-3 Compared to conventional types of cement, like zinc phosphate and glass ionomer, resin-based cement has improved adhesive and mechanical properties and it is less soluble. 2-4 However, because of their potential cytotoxic effect on pulp-dentine complex 5-7 and the possible occurrence of postoperative hypersensitivity owing to the absence of hermetical sealing on the tooth/cement interface provoked by a
