Abstract
Abstract Objective To evaluate the color adjustment potentials of monoshade universal composites in different shades of class I cavities. Methodology About 132 restorations were performed using monoshade universal composites (Omnichroma, OMNI; Essentia Universal; EU; Charisma Diamond One, CDO), and one simplyshade composite (NeoSpectra-ST, NEO) as control. A transparent silicone mold was used to provide standardized restorations on prefabricated class I cavities of acrylic dentures in B1, A2, and C4 shades. The assessment of color adjustment was performed immediately after, at 24 h, and at 2 weeks, through the cross-polarized dental photographs. The quantitative assessments were performed using a software (Digital Color Meter, Macintosh AC). The collected L*, a*, and b* coordinates from the restorations and the adjacent denture surfaces were used to provide Δ E 00 ⁎ \text{Δ}{E}_{00}^{\ast } values. Shapiro–Wilk, three-way Anova and Tukey HSD Test were used for the statistical analyses (p < 0.05). Results Among all composites and shades, the Δ E 00 ⁎ \text{Δ}{E}_{00}^{\ast } values were significantly the highest (1.27 ± 0.49a) for the immediately after assessments compared to the assessments at 1 day (1.01 ± 0.41b) and 2 weeks (0.97 ± 0.4c)(p < 0.05). At 24 h and 2 weeks of evaluations, the Δ E 00 ⁎ \text{Δ}{E}_{00}^{\ast } values for the control (0.42 ± 0.16H) were significantly the lowest (p < 0.05). Only the control presented imperceptible color changes for all the cavity shades (PT ≤ 0.8). After 2 weeks, EU (1.06 ± 0.32F) and OMNI (1.12 ± 0.18EF) presented significantly lower Δ E 00 ⁎ \text{Δ}{E}_{00}^{\ast } values compared to the CDO (1.29 ± 0.2CD) (p < 0.05). Restorations in lighter cavities presented significantly lower Δ E 00 ⁎ \text{Δ}{E}_{00}^{\ast } values. Conclusion Monoshade universal composites presented acceptable but perceptible color adjustment potentials in class I cavities without the shade selection procedure. Simplyshade composites following the shade selection might still be the best options regarding the level of color adjustment. Monoshade universal composites might provide better color adjustments in cavities with lighter shades.
摘要目的评价单色通用复合材料在不同色调的I类腔体中的调色能力。方法使用单色通用复合材料(Omnichroma, OMNI;Essentia普遍;欧盟;魅力钻石一号(CDO)和一个单色复合材料(NeoSpectra-ST, NEO)作为对照。采用透明硅胶模具对B1、A2和C4色度的预制丙烯酸义齿I类腔体进行标准化修复。在24小时和2周后立即通过交叉偏振牙齿照片进行颜色调整评估。使用软件(Digital Color Meter, Macintosh AC)进行定量评估。收集到的修复体和邻近义齿表面的L*、a*和b*坐标用于提供Δ E 00 \text{Δ}{E}_{00}^{\ast}值。采用Shapiro-Wilk、三向方差分析和Tukey HSD检验进行统计学分析(p < 0.05)。结果在所有复合材料和阴影中,评估后立即的Δ E 00 \text{Δ}{E}_{00}^{\ast}值与第1天(1.01±0.41b)和第2周(0.97±0.4c)值相比显著最高(1.27±0.49a) (p < 0.05)。在24 h和2周评估时,对照组的Δ E 00 \text{Δ}{E}_{00}^{\ast}值(0.42±0.16H)显著最低(p < 0.05)。只有对照组的所有空腔阴影颜色变化不明显(PT≤0.8)。2周后,EU(1.06±0.32F)和OMNI(1.12±0.18EF)的Δ E 00 \text{Δ}{E}_{00}^{\ast}值显著低于CDO(1.29±0.2CD) (p < 0.05)。较轻空腔的修复体具有较低的Δ E 00 \text{Δ}{E}_{00}^{\ast}值。结论单色通用复合材料在I类空腔中具有可接受但可感知的颜色调节电位,无需进行色度选择。关于颜色调整的水平,遵循阴影选择的简单阴影复合材料可能仍然是最好的选择。单色通用复合材料可能在浅色腔中提供更好的颜色调整。
期刊介绍:
Science and Engineering of Composite Materials is a quarterly publication which provides a forum for discussion of all aspects related to the structure and performance under simulated and actual service conditions of composites. The publication covers a variety of subjects, such as macro and micro and nano structure of materials, their mechanics and nanomechanics, the interphase, physical and chemical aging, fatigue, environmental interactions, and process modeling. The interdisciplinary character of the subject as well as the possible development and use of composites for novel and specific applications receives special attention.
