The in vitro occlusal wear oj two recently introduced, small-particle composite resins was evaluated. Twelve disks of each material were opposed by maxillary third molars and subjected to 300,000 masticatory cycles in a servohydraulic model of the human masticatory apparatus. Before ami after profiles of the surfaces of both the disks and the teeth were mapped and digitally recorded on magnetic disks. P-50 disks showed significantly (P <. 05) less volume loss than did Herculite disks. Enamel that opposed P-50 disks showed significantly CP <, 001) more wear than did enamel that opposed Herculite disks.
