Abstract

Achieving color match between natural teeth and restorative materials is crucial in dentistry. Factors such as the light source, brightness, and opacity influence tooth color, determined by light absorption and scattering within the material. Advances in CAD/CAM systems have enhanced prosthodontic treatments, particularly with new temporary materials, but data on their color stability and masking ability remains limited. However, data on the color stability and masking ability of these CAD/CAM materials is limited. Telio CAD-Temp and VITA CAD-Temp blocks were cut into slices and polished. Composite resin specimens were prepared using a custom-designed metal resin former and light-cured. Samples were paired randomly and assigned to experimental groups based on base type and thickness ( = 30). Samples were stored in a controlled environment for 24 h before color evaluation using an EasyShade V spectrophotometer. Color difference (Δ) was calculated using *, *, and * values. Statistical analyses included the Shapiro-Wilk test, Levene's test, and three-way ANOVA, with post-hoc comparisons using the Bonferroni method (α = 0.05). Δ was classified according to perceptibility (PT = 1.2) and acceptability (AT = 2.7) values.

摘要

在牙科领域，实现天然牙齿与修复材料之间的颜色匹配至关重要。诸如光源、亮度和不透明度等因素会影响牙齿颜色，而牙齿颜色是由材料内部的光吸收和散射决定的。CAD/CAM系统的进步提升了口腔修复治疗水平，特别是对于新型临时材料而言，但有关其颜色稳定性和遮盖能力的数据仍然有限。然而，这些CAD/CAM材料的颜色稳定性和遮盖能力的数据有限。将Telio CAD-Temp和VITA CAD-Temp块切成薄片并进行抛光。使用定制设计的金属树脂成型器制备复合树脂标本并进行光固化。样本随机配对，并根据基底类型和厚度分为实验组（= 30）。在使用EasyShade V分光光度计进行颜色评估之前，将样本在可控环境中保存24小时。使用*、和值计算颜色差异（Δ）。统计分析包括Shapiro-Wilk检验、Levene检验和三因素方差分析，事后比较采用Bonferroni方法（α = 0.05）。根据可察觉性（PT = 1.2）和可接受性（AT = 2.7）值对Δ进行分类。
