Abstract
This study was evaluated the wear resistance of 2 dentals materials in different pH medium. Wear of on dental resin (Super Lux) and on dental resin composite (VHL Hybrid) was measured with time. Wear tests were conducted using a conventional tribotesters. The wear device works like the pin-on-disk where a human tooth slides on the dental material sample. Two wear modes were considered: Dry and lubricated sliding. For the last mode, water (pH7), base (pH14) and acid (pH1.5) were used as lubricant. Wear depth (height loss) was measured using micrometric dial comparator. In general, the results show that the wear curves tend to a linear function and have similar trend and the wear quantity increases with time. Put aside the acid, the 2 other lubricants (bases and water) were minimized wear compared to the dry mode. The last mode gave a wear weaker than that of the acid and it for the used materials. In the other hand, the resin composite had the lower material loss than the dental resin and it for modes of wear considered.
