Methods: We established an experimental model of rat molars pulpitis, used homemade Calcium hydroxide compound as pulp-cap in pulpotomy of rats' teeth, Calvital and blank were det as the control groups. Forty rats' teeth in each group were observed using light microscope 4 and 12 weeks after pulpotomy.

Methods The resinic artificial teeth were deposited with 50nm or 100nm nanometer amorphous diamond film after pretreated with ultraviolet radiation or polarization.The effect of different methods of pretreatment and thickness of nanometer amorphous diamond films on the wearing resistance of resinic artificial teeth was evaluated.

分别用极化和紫外光照射的方法对人工牙进行预处理后，在其表面分别镀制50nm和100nm的纳米非晶金刚石薄膜，通过对其耐磨性能的测试，评价不同预处理方法和不同厚度薄膜对提高人工牙表面耐磨性能的影响。

Results Resinic artificial teeth deposited with 50nm amorphous diamond film after pretreated with polarization are most close to the natural enamel. Conclusion Nanometer amorphous diamond film improves significantly the wearing resistance of resinic artificial teeth.

结果：纳米非晶金刚石薄膜能显著提高树脂人工牙耐磨性能；两种预处理方法中，极化法实验组的耐磨性能明显优于紫外光照法实验组；极化处理后镀膜50nm的人工牙的耐磨性能最接近于天然牙釉质。
