本研究的目的是评价用不同的实验室聚合体系聚合的两种间接复合材料(Sinfony和Pearleste)的颜色稳定性。用其专有的聚合系统(Visio和PELCURE系统)或金属卤化物光聚合装置(Hyper LII)分别对60、120和180 S进行制备。在37℃保存24小时后,将样品浸入纯净水或茶中。用牙色度计(ShadeEye NCC)在黑白背景下测定从基线评估到4周后的颜色变化。测定了1976年L(*)a(*)b(*)值,并将其换算成DeltaE(*)(Ab)值。当材料与专有的Visio系统聚合时,浸泡在茶叶中的Sinfony材料的DeltaE(*)(Ab)值最高。在纯净水和茶叶中浸泡的珍珠岩材料基本上不受聚合体系的影响。在与Hyper LII基团聚合的12个基团中,11个基团的DeltaE(*)(Ab)值在Pearleste材料中显著低于Sinfony材料。可以得出结论,当材料与PearlCURE系统或与Hyper LII单元聚合时,Pearleste材料对颜色变化是稳定的。
The purpose of the current study was to evaluate the color stability of two indirect composite materials (Sinfony and Pearleste) polymerized with different laboratory polymerization systems. Disk specimens were prepared with their proprietary polymerization systems (Visio and Pearlcure systems) or with a metal halide light polymerization unit (Hyper LII) for 60, 120, and 180 s. After storage at 37 degrees C for 24 h, the specimens were immersed in either purified water or tea. Color change between baseline evaluation and after 4 weeks was determined with a dental chroma meter (ShadeEye NCC) using black and white backgrounds. CIE 1976 L(*)a(*)b(*) values were determined, and they were converted into DeltaE(*)(ab) values. The DeltaE(*)(ab) value of the Sinfony material immersed in tea was the highest when the material was polymerized with the proprietary Visio system. The Pearleste material immersed in purified water and tea was not affected substantially by the polymerization systems. Among the 12 groups polymerized with the Hyper LII units, DeltaE(*)(ab) values of 11 groups were significantly lower for the Pearleste material than for the Sinfony material. It can be concluded that the Pearleste material was stable against color change when the material was polymerized with either the Pearlcure system or with the Hyper LII unit.
