Abstract

We applied the Raman microprobe technique to analyze the chemical components at the interface layer between dentine and resin.A thin layer, about 5μm under interface, where both resin components and dentine components were present.These finding strongly suggest that resin reinforced dentine.In addition, 4-META or 4-MET appear to be more highly concentrated in this layer than in the resin side of the interface.
