Abstract

The present investigation studies the wear of dental resin filled by silicon carbide nanofibers (SiC NFs) concentrations. The materials used are dental resin and SiC NFs. Four groups of the resin specimens are prepared; one as received and three groups reinforced by SiC NFs in concentrations of 0.1, 0.2 and 0.3 wt. %. SiC NFs are manually mixed with the dental resin. The specimens are then light cured from both sides for 40, 60 and 99 seconds using a visible light curing unit. It was found that high curing times give high wear resistance compared to low curing times. Wear resistance displayed by all the tested specimens increased up to  0.1 wt. % SiC NFs , then decreased with increasing SiC NFs contents. Besides, composite containing 0.3 wt. % SiC NFs gives the lowest wear resistance. Based on the results, it can be noticed that wear resistance are considerably affected by curing times and SiC NFs concentrations.
