AB  - OBJECTIVE: To evaluate wear resistance and hardness of three kinds of new 
      composite resins. METHODS: Three kinds of new composite resins, Solidex, 
      Spectrum, Filtek Z350, were tested. Enamel as control group. A refited MG-200 
      wear machine was used in this study. Scanning electron microscope (SEM) was used 
      to observe the friction surface of each tested material. Hardness of each tested 
      material was determined by Vickers indentation technique. The data of wear and 
      hardness were analyzed by Mann-Whitney test and 1-way ANOVA. The relationship 
      between the hardness of the composites and the amount of wear of them was 
      determined by a regression analysis method. RESULTS: Filtek Z350 showed the 
      lowest volumetric wear and highest Vickers hardness in the composites (P < 0.05). 
      No significant differences in wear and hardness were observed between Solidex and 
      Spectrum (P > 0.05). Significant relationships were observed between the hardness 
      of the composites and the amount of wear of them (r = 0.968 6) (P < 0.05). 
      Different wear characters of the friction surface of the tested materials were 
      observed by SEM. CONCLUSION: Nanofilled composite was superior to the hybrid 
      composite in wear resistance and hardness.
