title: [An XPS and SEM study of the chemical-micromorphological characteristics of the dentin-resin adhesive interface. I].
abstract: In this preliminary note the author examined the chemical characterisation of dentin surfaces after treatment with an acid conditioner (nitric acid), using the XPS and Auger techniques, to evaluate whether micromorphological variations already reported by other authors are associated with changes of a chemical nature. The results of this study show an alteration of the superficial chemical component of dentin following treatment with the conditioner that would enable the realisation of closer binding with composite materials.
