摘要
In this article, an energy approach based on the correlation between dissipated friction energy and wear volume was used to compare wear resistances of human tooth enamel and four composite dental materials: Arkon, Ecusit, Ful-Fil, and Filtek. The results of the study showed that the wear resistance of enamel is approximately one order or more higher than the one obtained for the dental materials. The effectiveness of the approach used has also been shown. Scanning electron microscopy (SEM) examinations and chemical analysis surfaces subjected to tribological experiments made it possible to uncover substantial differences in the wear mechanisms occurring on enamel and the dental material surfaces. The wear mechanism of the dental materials used in the study is characterized mainly by chemical changes, while enamel is mainly subjected to physical transformations.
