OBJECTIVE
The objective of this study was to compare the color stability of acrylic teeth immersed in a pigmenting solution.
METHODS
An experimental study was carried out in 40 acrylic teeth from two commercial companies which were immersed in coffee and distilled water (control). The teeth were divided into 4 groups of 10 teeth each: Group-1 (Duratone-n® teeth immersed in distilled water), Group-2 (Duratone- n® immersed in coffee), Group-3 (Ivostar® teeth immersed in distilled water) and Group-4 (Ivostar® teeth immersed in coffee). The specimens were immersed in the respective solutions for 10 minutes a day for a period of 14 days. Finally, the samples were stored in an incubator at a constant temperature of 37 ° C. The color was recorded at two time-points (baseline time and at 14 days) using the Vita Easyshade® V spectrophotometer. The results were analyzed using the Stata 14 program.
RESULTS
Ivostar® teeth immersed in coffee (2.24) and distilled water (2.88) showest the highest ∆E values compared to Duratone-n® teeth immersed in coffee (1.53) and distilled water (1.60).
CONCLUSION
After exposure to coffee, the Duratone-n® brand teeth presented greater color stability compared to those of the Ivostar® brand.
目的
本研究的目的是比较浸泡在色素溶液中的丙烯酸牙的颜色稳定性。
方法
对来自两家商业公司的40颗丙烯酸牙进行实验研究，将其浸泡在咖啡和蒸馏水中（作为对照）。牙齿被分为4组，每组10颗：第1组（Duratone-n®牙浸泡在蒸馏水中），第2组（Duratone-n®浸泡在咖啡中），第3组（Ivostar®牙浸泡在蒸馏水中）和第4组（Ivostar®牙浸泡在咖啡中）。标本每天在各自的溶液中浸泡10分钟，持续14天。最后，将样品储存在37°C恒温的培养箱中。使用Vita Easyshade® V分光光度计在两个时间点（基线时间和14天时）记录颜色。使用Stata 14程序分析结果。
结果
与浸泡在咖啡（1.53）和蒸馏水中（1.60）的Duratone-n®牙相比，浸泡在咖啡（2.24）和蒸馏水中（2.88）的Ivostar®牙显示出最高的∆E值。
结论
与Ivostar®品牌的牙齿相比，Duratone-n®品牌的牙齿在接触咖啡后表现出更高的颜色稳定性。
