Abstract:
The in vitro wear of two types of composite resin veneering materials was determined by use of a three-body wear testing device. The wear of a microfilled high-filler content composite resin (Dentacolor) was less than that of a hybrid low-filler content one (Visio-Gem). The worn surface of Dentacolor material was smoother than that of Visio-Gem material. The wear-testing results and scanning electron micrographs demonstrated that the findings obtained by this wear-testing device correlated well with clinical findings.
