X‐ray photoelectron spectroscopy has been used to analyse the surface chemistry of dentine, the surface coverage of dentine by an experimental dentine bonding agent and the commercially available gluma Bond system and the hydrolysis of these adhesives. The cut dentine surface is shown to be of high inorganic composition. When this surface is treated with ethylenediaminetetracetic acid, the inorganic component was significantly reduced. The two adhesives were shown to spread effectively on the treated dentine surface and, following incubation in an aqueous environment, neither bonding system appeared to exhibit significant hydrolysis.
