Abstract

INTRODUCTION

Colour stability of composite materials is an essential property that greatly influences the longevity of dental restorations. Once in the oral cavity, dental materials must provide a stain resistance ability against environmental exposures, such as coffee. This experimental study compares the colour stability of two composite resin materials with differing nanocompositions.

OBJECTIVES

Analyze the effect of coffee on the colour stability of nanohybrid composites and nanocomposites.

MATERIAL AND METHODS

40 composites discs were utilized in total, with 20 fabricated of an Ormocer-based nanohybrid composite (Admira Fusion) and 20 of a UDMA-based nanocomposite (Normofill nanoceram) in shade A2. 10 discs of each material were then immersed in coffee or water for 12 days. Colour measurements were taken before and after the staining period using a VITA Easyshade spectrophotometer. The colour difference (ΔE) of both composites was calculated using the CIE Lab* values.

RESULTS

Both Ormocer-based nanohybrid composites (Admira Fusion) and UDMA-based nanocomposites (Normo fill nanoceram) exhibited a colour change after the 12-day period. The UDMA-based nanocomposite (Normo fill nanoceram) exhibited significantly more discolouration compared to the Ormocer-based nanohybrid composite (Admira Fusion).

CONCLUSIONS

Overall, there was a significant difference in colour generated by immersion in coffee as compared to water. Additionally, the Ormocer-based nanohybrid composite (Admira Fusion) exhibited significantly greater colour stability as compared to the UDMA-based nanocomposite (Normo fill nanoceram).

摘要

引言

复合材料的颜色稳定性是一项至关重要的特性，对牙科修复体的使用寿命有很大影响。一旦置于口腔中，牙科材料必须具备抵抗诸如咖啡等环境暴露的抗染色能力。本实验研究比较了两种具有不同纳米成分的复合树脂材料的颜色稳定性。

目的

分析咖啡对纳米混合复合材料和纳米复合材料颜色稳定性的影响。

材料与方法

总共使用了40个复合树脂圆盘，其中20个由基于Ormocer的纳米混合复合材料（Admira Fusion）制成，20个由基于UDMA的纳米复合材料（Normofill nanoceram）制成，色号为A2。然后将每种材料的10个圆盘分别浸泡在咖啡或水中12天。在染色期前后使用VITA Easyshade分光光度计进行颜色测量。使用CIE Lab*值计算两种复合材料的颜色差异（ΔE）。

结果

基于Ormocer的纳米混合复合材料（Admira Fusion）和基于UDMA的纳米复合材料（Normo fill nanoceram）在12天之后均出现了颜色变化。与基于Ormocer的纳米混合复合材料（Admira Fusion）相比，基于UDMA的纳米复合材料（Normo fill nanoceram）变色更为明显。
