Abstract

Hyperfine surface layer properties of three types of dental composite resins, highly-filled, conventional, and micro-filled resins, were studied using X-ray photoelectron spectroscopy (ESCA) by a combination of X-ray diffractometry and scanning electron microscopy (SEM). X-ray diffraction and SEM analysis showed clearly that each resin has different characteristics of SiO₂ particle size and distribution. ESCA depth resolution with argon ion etching indicated that in contrast to conventional and microfilled resins, carbon due to polymers of highly-filled resin decreases dramatically with increasing depth in the nanometer range of the resin-rich surface layer.
