Occlusal contact area (OCA) wear of two new composite restoratives

The occlusal contact area wear resistance of two new composite restoratives (Z250 and P60) was investigated and compared with two existing materials (Silux and Z100) using a reciprocal compression‐sliding test apparatus. Six wear specimens were made for each material and subjected to wear testing at...

Description
Summary:The occlusal contact area wear resistance of two new composite restoratives (Z250 and P60) was investigated and compared with two existing materials (Silux and Z100) using a reciprocal compression‐sliding test apparatus. Six wear specimens were made for each material and subjected to wear testing at 20 MPa with artificial saliva as lubricant. Wear depth (μm) was measured using profilometry every 20 000 cycles up to 120 000 cycles. Results were analysed using ANOVA/Scheffe’s test (P
