In vitro comparison of Biodentine and Riva LC interfaces with cervical dentin and Filtek Z350 in posterior class II open sandwich restorations

Abstract

Class II open sandwich restorations are routinely performed with resin-modified glass ionomer cement as a dentin substitute and with composite resin as an enamel substitute. Biodentine™ is a new calcium silicate-based material. Various authors have evaluated the microleakage of composite resin restorations, where different resin-modified glass ionomer cements and Biodentine, used as a dentin base, were compared in class II open sandwich restorations. The aim of this study was to evaluate and to compare in vitro the sealing ability of Biodentine™ and Riva LC with cervical dentin and Filtek Z350 in posterior proximal restorations using the dye penetration test.
