Abstract

Objective: To evaluate the shade-matching ability of single-shade resin-based composite restorations in different thicknesses using both instrumental and visual techniques.

Methods and materials: Cavities with 4 mm diameter and 2 mm (n=96) or 3 mm (n=96) depth were prepared in acrylic incisor teeth of shades A2, A3, B3, and C2 and restored with three single-shade resin composites, Omnichroma (Tokuyama Dental America, Encinitas, CA, USA [OM]), Vittra APS Unique (FGM Dental Group, Joinville, SC, Brazil [VU]), Zenchroma (President Dental, Allershausen, Germany [ZC]), and a microhybrid resin composite (Filtek 3M Z250 3M ESPE, St Paul, MN, USA [FZ]) of A2, A3, B3, and C2 shades. Readings were obtained using VITA Easyshade V spectrophotometer for the teeth and restorations. The CIEDE2000 (ΔE00) color difference formula was used, and the values were assessed using three-way analysis of variance (ANOVA). Forty-eight evaluators graded the shade match of 32 different specimens visually as (A) best shade match, (B) intermediate shade match, and (C) poor shade match.

Results: FZ material achieved satisfactory matches for both thicknesses, across all shades, and OM material demonstrated statistically significant lower shade matches than the ZC and the FZ materials (p<0.05). VU exhibited poor shade match with the highest ΔE00 value on C2 shade. According to the visual examination, the best shade matches were observed for FZ on A3-shade and ZC on C2-shade teeth.

Conclusions: Shade matching for 2 mm and 3 mm-thick composite resin restorations is material- and tooth-shade dependent.

单色复合树脂变色龙效应的仪器和视觉评估

目的使用仪器和视觉技术评估不同厚度的单色树脂基复合树脂修复体的色调匹配能力：在色调为 A2、A3、B3 和 C2 的丙烯酸门牙上制备直径为 4 毫米、深度为 2 毫米（n=96）或 3 毫米（n=96）的龋洞，并用三种单色树脂复合材料进行修复：Omnichroma（Tokuyama Dental America, Encinitas, CA、Omnichroma (Tokuyama Dental America, Encinitas, CA, USA [OM])、Vittra APS Unique (FGM Dental Group, Joinville, SC, Brazil [VU])、Zenchroma (President Dental, Allershausen, Germany [ZC])，以及 A2、A3、B3 和 C2 色调的微混合树脂复合材料 (Filtek 3M Z250 3M ESPE, St Paul, MN, USA [FZ])。使用 VITA Easyshade V 分光光度计对牙齿和修复体进行读数。使用 CIEDE2000 (ΔE00) 色差公式，并使用三方差分析（ANOVA）对数值进行评估。48 位评估员对 32 个不同试样的色调匹配度进行了目测分级：(A) 最佳色调匹配度；(B) 中等色调匹配度；(C) 差异色调匹配度：结果：两种厚度的 FZ 材料在所有色调上都达到了令人满意的匹配度，而 OM 材料的色调匹配度在统计意义上明显低于 ZC 和 FZ 材料（p 结论：2 毫米和 3 毫米厚的复合树脂修复体的色调匹配取决于材料和牙色。

期刊介绍： Operative Dentistry is a refereed, international journal published bi-monthly and distributed to subscribers in over 50 countries. In 2012, we printed 84 articles (672 pages). Papers were submitted by authors from 45 countries, in the categories of Clinical Research, Laboratory Research, Clinical Techniques/Case Presentations and Invited Papers, as well as Editorials and Abstracts. One of the strong points of our journal is that our current publication time for accepted manuscripts is 4 to 6 months from the date of submission. Clinical Techniques/Case Presentations have a very quick turnaround time, which allows for very rapid publication of clinical based concepts. We also provide color for those papers that would benefit from its use. The journal does not accept any advertising but you will find postings for faculty positions. Additionally, the journal also does not rent, sell or otherwise allow its subscriber list to be used by any other entity
