A Raman microprobe technique was applied to analyse the chemical components at the interface layer between dental adhesive resins and dentine. Raman spectra from each spot ( ca. 2 μm in diameter) on the flat surface perpendicular to the interface were measured individually. These spectra indicate the coexistence of the resin and dentine components in a thin layer ( ca. 5 μm in depth) of the dentine side. This provides spectroscopic evidence for the formation of resin‐reinforced dentine.
