Abstract

UNLABELLED

The longevity and durability of composite resins are influenced by the actions of water, saliva, drinks, food and features of the oral environment.

OBJECTIVE

The aim of this study was to evaluate the effect of mouthwashes containing alcohol on the surface hardness, sorption and solubility of composite resins.

METHODS

Disc-shaped specimens were prepared with two composite resins Z250 (Z2) and Z350XT (Z3). Measurements of Vickers hardness were performed before and after immersion in Plax, PerioGard, Listerine, ethanol and distilled water for 12 h at 37°C, followed by a further 12 h at 37°C in artificial saliva. Sorption and solubility were performed according to ISO 4049. Data were analysed using one-way ANOVA and Tukey tests (α=0.05).

RESULTS

None of the mouthwashes significantly reduced the hardness of the resin Z2 (p>0.05). The greatest change in resin Z3 hardness was produced by PerioGard (p<0.01). Plax produced the lowest changes in the sorption and solubility of resins Z2 and Z3 (p<0.01), followed by Listerine and PerioGard.

CONCLUSIONS

The sorption and solubility properties of the composite resins were more altered by mouthwashes than the surface hardness.

复合树脂的寿命和耐久性受水、唾液、饮料、食物以及口腔环境特征的影响。

目的

本研究旨在评估含酒精漱口水对复合树脂表面硬度、吸附性和溶解性的影响。

方法

用两种复合树脂Z250（Z2）和Z350XT（Z3）制备圆盘形试件。在37℃下将试件浸泡于Plax、PerioGard、李施德林漱口水、乙醇和蒸馏水中12小时，然后在37℃的人工唾液中再浸泡12小时，分别在浸泡前后测量维氏硬度。根据ISO 4049进行吸附性和溶解性测试。采用单向方差分析和Tukey检验分析数据（α=0.05）。
