dc.description.abstract This work presents a study of the wear of four dental composites (Concept, XRV, Maxxim, and Belleglass) which are in commercial use. The wear testing was performed using an Atomic Force Microscope (AFM). Several scanning techniques and various cantilevers were attempted. Finally use of a stainless steel cantilever with a tungsten bead attached resulted in quantifiable wear. AFM imaging in contact mode was used for evaluation of the wear tests. Wear rates are reported as volume per 100,000 scans. The AFM measured wear rates rank the tested composites from most to least wear as follows: Concept highest volume of wear XRV Maxxim BelleGlass least volume of wear. Micro-hardness measurements were also conducted. en_US
