Comparatively assess the fluorescence and color adjustment potentials of paste-type and flowable resin composites performed in cervical restorations.
Five paste-type resin composites and 5 highly-filled flowable composites were investigated (n=5 for each). Class V cavities on 50 extracted A2 shade human central incisors were restored. Cross-polarization (CP) and fluorescence illumination (FI) images were recorded for each restoration. Lab* values were analyzed using the Photoshop software and color adjustment (ΔE) and fluorescence adjustment (ΔE) levels were quantitatively assessed. Kruskal Wallis Test, Independent Samples t Test, One Way Anova-Welch test, and Pearson Correlation were used for the statistical analyses. The deemed significance was set at p<.050.
Paste-type composites presented significantly lower ΔE and ΔE values than the flowable composites (p=.006 and p<.001 respectively). ΔE and ΔE values were positively correlated (r=0.584; p<.001). Paste-type Gaenial A'chord presented the lowest ΔE value [7.67 (5.35 - 10.99)], while Estelite Asteria presented significantly the highest [19.94 (17.08 - 22.17)]. Charisma Diamond One Flow presented the highest ΔE value [3.25 (3.13 - 3.39)] and Gaenial A'chord presented the lowest [0.79 (0.48 - 0.87)] which was the only imperceptible score (<0.8). The only clinically acceptable color adjustment was found for Geanial Universal Injectable [1.06 (0.73 - 1.62)] among the flowable composites. ΔE and b* values were positively correlated (r=0.493; p<.001).
Color adjustment level and fluorescence adjustment level were considered coherent for particular composite brands. At the same time, both were better for the paste-type composites than the flowable composites on A2 base shade class V restorations. Fluorescence adjustment potential as well as the color adjustment potential varied among different composite brands regarding paste-type and flowable composites.
Understanding both the color and fluorescence adjustment potentials of paste-type and flowable resin-based composite materials is clinically vital to achieve the high-end esthetics.
比较评估在颈修复中使用的糊状和流动性树脂复合材料的荧光和颜色调整潜力。
研究了 5 种糊状树脂复合材料和 5 种高填充流动性复合材料（每种 5 个）。在 50 颗提取的 A2 色调人中切牙的 5 类 V 腔中进行修复。为每个修复体记录交叉偏振（CP）和荧光照明（FI）图像。使用 Photoshop 软件分析 Lab*值，并定量评估颜色调整（ΔE）和荧光调整（ΔE）水平。使用 Kruskal Wallis 检验、独立样本 t 检验、单向方差分析-Welch 检验和 Pearson 相关进行统计分析。设定显著水平为 p<.050。
糊状复合材料的ΔE 和 ΔE 值明显低于流动性复合材料（p=.006 和 p<.001）。ΔE 和 ΔE 值呈正相关（r=0.584;p<.001）。Gaenial A'chord 糊剂表现出最低的ΔE 值[7.67（5.35-10.99）]，而 Estelite Asteria 表现出最高的[19.94（17.08-22.17）]。Charisma Diamond One Flow 表现出最高的ΔE 值[3.25（3.13-3.39）]，而 Gaenial A'chord 表现出最低的[0.79（0.48-0.87）]，这是唯一可察觉的分数（<0.8）。在流动性复合材料中，仅 Geanial Universal Injectable 可实现可接受的临床颜色调整[1.06（0.73-1.62）]。ΔE 和 b*值呈正相关（r=0.493;p<.001）。
对于特定的复合材料品牌，颜色调整水平和荧光调整水平被认为是一致的。同时，在 A2 基础色调 5 类 V 修复体中，与流动性复合材料相比，糊状复合材料的颜色调整和荧光调整水平更好。在糊剂和流动性复合材料方面，不同复合材料品牌的荧光调整潜力和颜色调整潜力存在差异。
了解糊剂和流动性树脂基复合材料的颜色和荧光调整潜力对于实现高端美学至关重要。
