A comparative study of tribological behaviour of dental composites and tooth enamel: An energy approach

Abstract

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.

“…It was further concluded that incorporation of nanoalumina increased hardness and wear resistance of the composites. Sajewicz 13 compared the wear resistance of human tooth enamel and four different commercially available dental materials such as Arkon, Ecusit, Ful-Fil, and Filtek, and found that Filtek dental material exhibited better wear resistance as compared with other materials because it consisted of more amounts of nanofillers. Nowadays, most of the researches are focused on the material properties, physical characterizations, chemical composition, as well as the wear resistance of the dental composites.…”

“…No animal or human studies were identified. The included studies are listed in the Table 1 [22,[24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. The number of publications increased through the years and 13 of 17 articles were published after 2010.…”

“…The number of publications increased through the years and 13 of 17 articles were published after 2010. In addition, 13 studies were published in journals that covered research into mechanical engineering or technology of nanosized and nanostructured materials, including advanced ceramic materials and reinforced plastics and polymer composites [25][26][27][28][29][30][31][32][33][35][36][37][38]; three studies were published in journals that focused on the application of biomaterials and tissue engineering in the medical sciences [24,34,39] and only one was published in a dentistry journal [22].…”

“…Other studies evaluated the effect of temperature and immersion in beverages [26], thermocycling [28], smokeless tobacco at different aging times [34], and different light curing units [39] on mechanical behavior of dental resins. Finally, one article compared the tribological behavior of human enamel with that of some resin composites [32].…”

“…The tribological behavior was investigated for volume loss/penetration depth [22,25,26,29,30,[32][33][34][35]39], roughness [27,28,31,39], plasticity index [26], coefficient of friction [24,25,27,28,30,33,36], wear rate [24,27,33,[36][37][38], Vickers hardness [24,[26][27][28][29]31,36,39], elastic modulus [28,29,35], abrasion resistance [35], flexural [28], and compressive [33] strength.…”
