Abstract

OBJECTIVES

To compare the relative effects of cigarette smoke (CS), electronic cigarette (EC), red wine, coffee, and soy sauce on the color of enamel, dentin, and composite resin restorations, as well as the effects of whitening treatments.

METHODS

Seventy premolars with composite restorations were exposed to CS, EC aerosol (a novel EC device with MESH™ technology [P4M3 version 1.0, Philip Morris International]), red wine, coffee, and soy sauce for 56 min/day for 15 days. Two whitening sessions with 6% and 35% hydrogen peroxide (HO) were performed on the exposed samples. Teeth exposed to CS and EC aerosol were also brushed with whitening toothpaste for 3 weeks. Color match of resin restorations was assessed, and color changes were compared after exposure and after whitening treatments.

RESULTS

Discolorations in enamel, dentin, and composite resin were observed in the order of red wine > CS > soy sauce > coffee > EC. Color mismatch between enamel and resin restorations occurred only in red wine and CS groups. Brushing with whitening toothpaste removed discoloration caused by EC aerosol; HO treatments were necessary to eliminate discolorations caused by coffee and soy sauce. Discolorations of dentin and resin restorations could not be completely removed by whitening treatments, and color mismatch remained in teeth exposed to red wine and CS.

CONCLUSION

Red wine and CS cause significant tooth discoloration and color mismatch in enamel and resin restorations that are not reversible by whitening treatments. Tooth discoloration associated with EC aerosol was minimal and could be removed by brushing with whitening toothpaste.

CLINICAL SIGNIFICANCE

Red wine drinkers and cigarette smokers have increased risks for tooth discoloration and color mismatch between enamel and composite resin restorations. Whitening treatments may not be effective in correcting the color mismatch. Tooth discoloration associated with EC aerosol is minimal.

摘要

目的

比较香烟烟雾（CS）、电子烟（EC）、红酒、咖啡和酱油对釉质、牙本质和复合树脂修复体颜色的相对影响，以及美白处理的效果。

方法

将 70 颗带有复合修复体的前磨牙暴露于 CS、EC 气溶胶（一种具有 MESH™技术的新型 EC 设备[P4M3 版本 1.0，菲利普莫里斯国际公司]）、红酒、咖啡和酱油中，每天暴露 56 分钟，持续 15 天。对暴露的样本进行两次 6%和 35%过氧化氢（HO）的美白处理。对暴露于 CS 和 EC 气溶胶的牙齿也用美白牙膏刷牙 3 周。评估树脂修复体的颜色匹配，并比较暴露后和美白处理后的颜色变化。

结果

釉质、牙本质和复合树脂的变色顺序为红酒>CS>酱油>咖啡>EC。只有在红酒和 CS 组中观察到釉质和树脂修复体之间的颜色不匹配。用美白牙膏刷牙可去除 EC 气溶胶引起的变色；HO 处理对于消除咖啡和酱油引起的变色是必要的。牙本质和树脂修复体的变色不能通过美白处理完全去除，暴露于红酒和 CS 的牙齿仍存在颜色不匹配。
