Wear of anterior and posterior composites under accelerated aging

ABSTRACT

The two-body abrasion, compressive strength, and single-pass sliding parameters of three anterior and four posterior composites were determined. Single-pass samples were aged for 900 hours in a weathering chamber. Compressive strength was not correlated with either two-body abrasion or single-pass sliding parameters. The quarters-filled composites had the lowest values of two-body abrasion. The light-cured composites were among the composites with high values of two-body abrasion and track width before aging
