Abstract
Wear characteristics of dental amalgams were investigated by in vivo and in vitro tests. Wear of dental amalgam was studied and evaluated using a three - body abrasion test and Pin-On-Disk method. Porcelain was used for preparing disk and materials such as toothpaste, artificial saliva and naturally saliva were used as the third material that was contributed in tribologic system The results showed that effects of various toothpastes on the wear of dental amalgam are considerably different and size, shape and chemical composition of amalgam are important too.
