Resin composite restorative materials can mimic the natural color and shade of the tooth. However, exogenous colorants from food and drinks can stain them due to adsorption. The influence of Indian food colorants and spices on resin composite restorations has not been evaluated extensively.
This study aims to evaluate the staining capacity of microhybrid and nanohybrid resin-based composites, to saffron extract, tandoori powder, and turmeric powder.
Forty samples of microhybrid (Kulzer Charisma) and nanohybrid (3M Filtek Z350) resin composites were prepared using an acrylic template of dimension 5 mm × 3 mm. They were randomly divided into four groups and immersed into solutions of saffron extract, tandoori powder, and turmeric powder. Distilled water was used as the control group. Color values (LFNx01, aFNx01, bFNx01) were measured by colorimeter using the CIE LFNx01aFNx01bFNx01 system before and after 72 h of immersion. Color differences ΔEFNx01ab were statistically analyzed.
Two-way ANOVA and post-hoc Tukey (honest significant difference) test were done using IBM SPSS Statistics for Windows, Version 19.0. Armonk, NY: IBM Corp.
: All the immersion media changed the color of the resin composites to varying degrees. However, turmeric solution showed the maximum mean color variation ΔEFNx01ab of 14.8 ± 2.57 in microhybrid resin composites and 16.8 ± 3.50 in nanohybrid resin composites.
Microhybrid and nanohybrid resin composites tend to stain to Indian food colorants, especially to turmeric powder.
树脂复合材料修复材料可以模仿牙齿的天然颜色和色泽。然而，来自食物和饮料的外源性着色剂会因吸附作用而使其染色。印度食用色素和香料对树脂复合材料修复体的影响尚未得到广泛评估。
本研究旨在评估微混合和纳米混合树脂基复合材料对藏红花提取物、坦都里粉和姜黄粉的染色能力。
使用尺寸为5毫米×3毫米的丙烯酸模板制备40个微混合（库尔泽魅力）和纳米混合（3M Filtek Z350）树脂复合材料样本。将它们随机分为四组，并浸入藏红花提取物、坦都里粉和姜黄粉的溶液中。蒸馏水用作对照组。在浸泡72小时前后，使用色差仪通过CIE LFNx01aFNx01bFNx01系统测量颜色值（LFNx01、aFNx01、bFNx01）。对颜色差异ΔEFNx01ab进行统计分析。
使用IBM SPSS Statistics for Windows 19.0版进行双向方差分析和事后Tukey（诚实显著差异）检验。纽约州阿蒙克：IBM公司。
所有浸泡介质均使树脂复合材料的颜色发生了不同程度的变化。然而，姜黄溶液在微混合树脂复合材料中的平均颜色变化ΔEFNx01ab最大，为14.8±2.57，在纳米混合树脂复合材料中为16.8±3.50。
微混合和纳米混合树脂复合材料容易被印度食用色素染色，尤其是姜黄粉。
