摘      要：The objective of this study was to evaluate the effect of functionalizing a dental adhesive resin with YbF_3/SiO_2 fillers for use as *** of YbF_3/SiO_2 were obtained with the high-energy mechanical milling method and characterized by both physical and chemical *** characterization,the particles were sieved and silanized prior to being incorporated into an adhesive *** stability of the particle suspension was then *** light activation,the radiopacity,degree of conversion,flexural strength and elastic modulus were *** dental adhesive resins with 10 and 15 wt% of filler provided satisfactory radiopacity,while flexural strength and elastic modulus were not *** degree of conversion was statistically lower than that of the control(p0.05).The method used for incorporating the tested ytterbium fluoride/silicon dioxide particles at concentrations of 10 and 15 wt% was shown to be feasible for the development of a radiopaque dental adhesive system.
