Abrasive and sliding wear of resin composites for dental restorations

The aim of this work was to study the abrasive and reciprocating sliding wear resistance of four commercial resin composites for dental restorations. Resin composite samples were divided into four groups considering the different materials and then separated for compressive, abrasive and sliding tests (n=10). Micro-abrasion tests were performed against a stainless steel rotating ball on 3 N normal load for 300 revolutions in the presence of a...
