Abstract

Background: The aim of this study was to evaluate the surface color stability, transluceny and gloss changes of seven different universal resin composites after bleaching treatment protocol.

Methods: Fifty-six disc-shaped specimens were prepared, with eight specimens each of the universal resin composites Filtek Z250 (F), Filtek Universal (FU), Harmonize (H), Vittra Unique (VU), Omnichroma (O), Essentia Universal (EU), Charisma Diamond One (CDO). Prepared specimens were divided into two for color change, translucency, gloss (n = 8). Initial color and gloss measurements and translucency calculations were made on the prepared samples. After measurements, in-office bleaching gel was applied to the specimen surfaces three times, and each application time was 15 min. After the bleaching protocol, the measurements were repeated, and the values were statistically analyzed using the one-way ANOVA, Tukey HSD test, Kruskal-Wallis test, Dunn's test, Paired samples t-test (p < 0.05).

Results: Vittra Unique group had statistically significantly higher ΔE values than the FU, H and EU groups (p < 0.05). CDO had significantly higher ΔE than the H group (p < 0.05). O had higher TP values than all other groups for T0 and T1 (p < 0.05). A significant decrease in gloss values was observed after bleaching in all material groups compared to the initial.

Conclusions: The organic content of resin composites is an important factor in color stability, with higher molecular weight resins may being less affected by bleaching agents.

室内漂白剂对通用树脂复合材料光学性能的影响：体外分析。

背景：本研究的目的是评价7种不同的通用树脂复合材料在漂白处理方案后的表面颜色稳定性、透光性和光泽变化。方法：制备56个圆盘形标本，其中Filtek Z250 (F)、Filtek universal （FU）、Harmonize (H)、Vittra Unique （VU）、Omnichroma (O)、Essentia universal （EU）、Charisma Diamond One （CDO）通用树脂复合材料各8个标本。将制备好的标本按颜色变化、透明度、光泽度分为两组（n = 8）。对制备的样品进行了初步的颜色和光泽测量以及半透明性计算。测量结束后，将办公室内漂白凝胶涂抹于标本表面三次，每次涂抹时间为15 min。漂白方案完成后，重复测量，并采用单因素方差分析、Tukey HSD检验、Kruskal-Wallis检验、Dunn检验、配对样本t检验(p)进行统计学分析。结果：Vittra Unique组ΔE值显著高于FU、H和EU组(p)。树脂复合材料的有机含量是影响其颜色稳定性的重要因素，分子量较高的树脂受漂白剂的影响较小。
