Abstract

BACKGROUND

The aim was to compare and assess the effects of tocopherol, glutathione (GSH), and sodium ascorbate (SA) on bleached enamel's resin tooth-colored microshear bonding capacity.

MATERIALS AND METHODS

After flattening, out 120 sound human premolars and dividing the teeth into four groups: Group A: No bleaching or antioxidants (the control group), Group B received SA, Group C received GSH, and Group D received tocopherol.

RESULTS

The resin tooth-colored was bonded in just one step, and the microshear degree of adhesion of tooth-colored to bleached enamel was evaluated. The data were analyzed using a one-way ANOVA followed by the Tukey test.

CONCLUSION

The microshear degree of adhesion (SBS) of tooth-colored resin diminishes after bleaching. Nonetheless, antioxidants such as SA and GSH can effectively restore the reduced degree of adhesion capacity.

摘要

背景

目的是比较和评估生育酚、谷胱甘肽（GSH）和抗坏血酸钠（SA）对漂白牙釉质树脂牙齿颜色微剪切粘结能力的影响。

材料与方法

将120颗健康人前磨牙磨平后分为四组：A组：不进行漂白或使用抗氧化剂（对照组），B组接受SA，C组接受GSH，D组接受生育酚。

结果

树脂牙齿颜色仅一步粘结完成，并评估了牙齿颜色与漂白牙釉质的微剪切粘结程度。数据采用单因素方差分析，随后进行Tukey检验。

结论

漂白后牙齿颜色树脂的微剪切粘结程度（SBS）降低。尽管如此，SA和GSH等抗氧化剂可以有效恢复降低的粘结能力程度。
