摘要
目的 :分析并比较光固化和化学固化玻璃离子水门汀及几种临床常用遮色剂的遮色力。方法 :以玻璃离子及遮色剂作为实验对象 ,经测色后分别计算在黑白底色上的△E。结果 :LGIC、CIC的平均△E黑 -△E白 为 14 96± 1 76,三种临床常用遮色剂平均值为 3 5 2 3± 6 0 1。结论 :LGIC、GIC的遮色力比临床常用遮色剂大 ,且相差非常显著 (P <0 0 1)。
Objective: To analyze and compare the opacity of LGIC , GI C and other commonly-used opaquers. Methosds: ΔE of LGIC, GIC an d other opaquers was assessed by means of of spectrophotmetric color measurement with black and white background. Results: The average ΔE bla ck -ΔE white of LGIC and GIC was 14 96±1 76, while that of another thr ee commonly-used opaquers was 35 23±6 01. Conclusion: The op acity of LGIC and GIC is stronger than that of commonly-used opaquers(P<0 01) .
