Abstract

A study on the assessment and correlation of the wear and surface roughness of minifilled and nanofilled composites finished and polished by different methods was presented. The four sequences were tungsten carbide burs plus Al2O3-impregnated brush (CbBr), tungsten carbide burs plus diamond-impregnated cup (CbCp), diamond burs plus brush (DmBr), and diamond burs plus cup (DmCp). Significantly smoother surface were attained with the sequences CbBr and CbCp, whereas DmCp yielded the roughest surface. Regardless of the finishing/polishing technique, the nanofilled composite exhibited the lowest testing roughness and wear.
