Sliding Wear of Various Composite Resins and Bovine Enamel

Sliding wear tests were performed on 8 different types of composite resins using bovine enamel as the counterface. The wear level of the composites and the effect induced on the bovine enamel by sliding these composites were examined. Filler content and mechanical properties of composite resins were also studied and evaluated in relation to wear. The wear of microfilled resins was less than that of other resins. A positive correlation was observed between the wear of the resin and the wear depth of the bovine enamel. The filler content, the Knoop hardness and the elastic modulus of resin correlated with the wear level.
