Paper Title:
Fluoride Release from Composite Materials for Dental Fillings
  Abstract

Fluoride release from composite materials for dental fillings depending on the type of powder filler and dynamical loading is the main problem considered in the paper. The fillers used for research were fluoridated glass (based on Ba-Sr-Al-P-Na-silicate glass), ytterbium fluoride (YbF3) as a fluoride source and nanosilica. In order to estimate the influence of the usage loading value on fluoride release from analyzed samples, the wear tests were carried out by means of special tribotester in presence of phosphate buffer as a lubricant. After friction processes the fluoride release tests were performed in phosphate buffer using direct potentiometry method with fluoride selective electrode. The fluoride emission was analyzed on the basis of: 1) type and amount of fillers powder, 2) using loading. Surface roughness was also investigated. The surface of each composite was analyzed by means of SEM.
