Abstract

Objectives

This in vitro study aimed to investigate the color changes of the bracket-bonded tooth surfaces after the use of 4 different mouthwashes.

Materials and methods

A total of 100 human premolar teeth were randomly divided into 10 equal groups. Color values (L*a*b*) of the buccal surfaces of each tooth were assessed using a digital spectrophotometer. Then the brackets were bonded. The groups were put either in sterile saline (4 test+1 control) or artificial saliva (4 test+1 control) solutions, and test groups were immersed in their mouthwashes (Colgate Plax, Listerine Cool Mint, Klorhex, and Tantum Verde) for 1 min each in the morning/evening to simulate the mouth washing for 21 days after the bonding. After the debonding and finishing procedures, final color measurements were performed. Color changes (∆E) were calculated.

Results

All of the parameters showed statistically significant differences among the groups. The least noticeable color changes were detected in the control groups. The most noticeable color change (ΔE) was observed in the Tantum Verde + artificial saliva group, followed by Tantum Verde + sterile saline and Klorhex + artificial saliva groups, all of which were significantly higher than the control groups.

Conclusion

The use of mouthwashes during orthodontic treatment may cause noticeable changes in tooth color. Listerine Cool Mint may be the choice of mouthwash with its less discoloring effects. Artificial saliva should be preferred in similar in vitro studies to reflect the oral environment better.

Clinical relevance

Mouthwash use during orthodontic treatment may result in different levels of enamel discoloration.

漱口水对托槽粘结牙齿表面变色的影响:一项体外研究

摘要

目标

这项体外研究旨在研究使用4种不同漱口水后托槽粘结牙齿表面的颜色变化。

材料和方法

将总共​​100颗人类前磨牙随机分为10组。使用数字分光光度计评估每个牙齿的颊面颜色值(L * a * b *)。然后将托架粘合在一起。将各组放入无菌盐水(4个测试+1对照)或人工唾液(4个测试+1对照)溶液中,然后将测试组浸入漱口液(Colgate Plax,Listerine Cool Mint,Klorhex和Tantum Verde)中,早晨/晚上各1分钟,以模拟粘合后21天的漱口水。在脱胶和整理步骤之后,进行最终的颜色测量。计算了颜色变化(∆E)。

结果

所有参数在各组之间显示出统计学上的显着差异。在对照组中检测到最不明显的颜色变化。在Tantum Verde +人工唾液组中观察到最明显的颜色变化(ΔE),其次是Tantum Verde +无菌盐水和Klorhex +人工唾液组,所有这些均显着高于对照组。

结论

在正畸治疗期间使用漱口水可能会导致牙齿颜色发生明显变化。Listerine Cool Mint变色效果较小,可能是漱口水的选择。在类似的体外研究中应首选人工唾液,以更好地反映口腔环境。

临床相关性

正畸治疗期间漱口水可能导致牙釉质变色程度不同。
