Operating variables affecting the working time of a dual-cure composite luting cement

Dual-cure composite resin luting cements are increasingly being used for the cementation of porcelain veneers, composite and ceramic inlays, onlays and crowns. This investigation assessed the effect of a dual-cure adhesive (Bondlite) on the working time of a dual-cure composite resin luting cement (Porcelite Dual-Cure). An oscillating rheometer was used to measure the working time of the composite resin luting cement with and without prior application of dual-cure adhesive. The results demonstrated that use of the dual-cure adhesive significantly reduced the working time of the manufacturer's dual-cure composite resin luting cement.
