Wear characteristics of aged and unaged composite restorative materials were compared using single-pass sliding. There were differences in wear track widths, tangential forces, and surface failure classifications between aged and unaged composites. Changes in surface wear characteristics upon aging were attributed to surface degradation in the composite materials.
