Abstract

Aim: To assess the effect of modeling liquid on the microhardness of single-shade universal composites.

Materials and methods: A total of 60 disk-shaped samples were prepared in six groups [Omnichroma (OM), Essentia Universal (EU), Vittra APS Unique (VA), OM + Signum, EU + Signum, and VA + Signum] for surface microhardness measurements. Samples were stored in a coffee solution for 7 days and after that bleached with an Office bleaching agent (Total Blanc Office). Surface microhardness was measured for baseline, after staining, and after bleaching. A two-way analysis of variance test was used for statistical analysis (P < 0.05).

Results: In terms of microhardness, there is a statistically significant difference (P < 0.05) between the two categories with and without modeling liquid. The alterations in microhardness measurements at baseline, after staining, and after bleaching are statistically significant (P < 0.05). The Essentia groups showed the lowest microhardness findings at all measurement times. Microhardness values decreased significantly more when EU was applied along with modeling liquid than when it was not applied at different intervals.

Conclusions: Modeling liquid affects the microhardness of single-shade composites. Microhardness is reduced when modeling liquid is used for all three single-shade universal composite resins at three different times.

模型液对单色复合树脂显微硬度的影响：体外研究

目的：评估造型液对单色通用复合材料显微硬度的影响：共制备了 60 个圆盘状样品，分为六组[Omnichroma (OM)、Essentia Universal (EU)、Vittra APS Unique (VA)、OM + Signum、EU + Signum 和 VA + Signum]进行表面显微硬度测量。样品在咖啡溶液中存放 7 天，然后用办公室漂白剂（Total Blanc Office）漂白。分别测量基线、染色后和漂白后的表面微硬度。采用双向方差分析进行统计分析（P < 0.05）：在显微硬度方面，使用和不使用造型液的两类牙面之间存在显著差异（P < 0.05）。基线、染色后和漂白后的显微硬度测量值的变化均有统计学意义（P < 0.05）。Essentia 组在所有测量时间的显微硬度结果都最低。在不同的时间间隔内，与不使用造型液时相比，使用 EU 和造型液时显微硬度值的下降幅度更大：结论：造型液会影响单色复合材料的显微硬度。在三个不同时间段对所有三种单色调通用复合树脂使用建模液时，显微硬度都会降低。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
