目的：比较2种二氧化锆的色度学指标和透光率，以指导临床修复。方法??制作Vita?In-Ceram?YZ二氧化锆试件共36块，分为6组。其中5组分别采用染色剂LL1~LL5号按照染色步骤进行染色，第6组为空白对照组，烧结后得到0.5?mm厚度试件。制作厚度为0.5?mm?Sirona?inCorisZI二氧化锆试件共30块，分为5组，每组6块。对11组试件进行测色，指标包括L*、a*、b*值和可见光积分透射比（τ值）。结果???不论是Vita或是Sirona瓷块，随着瓷块号增加，其瓷块的明度（L*）值亦随之下降。同时可见光积分透射比（τ值）亦随之下降。Vita?In-Ceram?YZ和Sirona?InCoris?ZI不同颜色的二氧化锆透光率存在差异，颜色相近的瓷块透光率相似，但色度差较大。结论??选择透明度高的二氧化锆材料可以更好地再现牙齿的颜色。
