The wear of cental amalgam was studied by single- and double-pass sliding and by a silicon carbide abrasion test. A dispersed amalgam showed significantly better resistance to two-body abrasion than the spherical amalgams tested. The wear amalgam was determined by resistance to penetration and by a ductile mode of surface failure over the load range studied. Differences in the wear of amalgam a...

OBJECTIVES The aims of this study were to test whether the bond strength of a hybrid composite and a PMMA-based veneer to CAD/CAM polymers would improve after pre-treatment and to evaluate the failure types after debonding. MATERIALS AND METHODS Three types of PMMA-based (CAD-Temp, artBloc Temp and TelioCAD) CAD/CAM blocks were obtained (N = 360, n = 15 per test group). They were divided into...

Ravelling atau butiran lepas adalah salah satu jenis kerusakan jalan berupa disintegrasi permukaan perkerasan aspal yang disebabkan pelepasan partikel agregrat berkelanjutan, berawal dari menuju ke bawah pinggir dalam. dapat terjadi karena beberapa faktor, diantaranya kadar dan air void. Penelitian ini bertujuan untuk mengetahui pengaruh void sebanyak 2%, 4%, 7% 4,5%, 5,5%, 6,5% terhadap ravell...

Context: Nanocomposites are becoming popular today because of the manufacturers claiming high surface smoothness and good abrasion resistance properties thus improving the longevity of the restoration. Aims: This in vitro study was carried out to investigate the effect of nanofillers on surface roughness and abrasion resistance of nanofilled compositeFiltek Z350 (3M ESPE) and nanohybrid composi...
