Abstract

This study investigates how the cavity depth of restorations influences the color adjustment potential of universal shade bulk-fill resin composites. Standard cavities, with diameters of 4 mm and depths of either 2 or 4 mm, were created at the center of artificial teeth occlusal surfaces. A structural-colored bulk-fill resin composite and two pigment-incorporated universal shade bulk-fill resin composites were used. Each resin composite was placed into the cavity to assess its color adjustment potential in relation to the artificial tooth color. Following application, the resin composites' surfaces were polished using diamond-impregnated silicone polishers. Color difference analysis revealed ΔE*ab values of 3.3-4.6 and 2.2-9.6 for structural-colored resin composites and pigment-incorporated universal shade resin composites, respectively, as well as ΔE₀₀ values of 2.7-3.4 and 1.7-5.8 for these resin composites, respectively. These findings suggest that the tested bulk-fill resin composites' color adjustment potential was influenced by restoration depth.

通用遮光散装树脂复合材料的色彩调节潜力。

本研究探讨了修复体的龋洞深度如何影响通用色散填充树脂复合材料的颜色调节潜力。在人工牙齿咬合面的中心位置制作了直径为 4 毫米、深度为 2 毫米或 4 毫米的标准牙洞。使用一种结构色体填充树脂复合材料和两种颜料混合通用色体填充树脂复合材料。将每种树脂复合材料放入龋洞中，以评估其与人工牙齿颜色的调色潜力。使用后，使用金刚石浸渍硅树脂抛光剂对树脂复合材料的表面进行抛光。色差分析表明，结构色树脂复合材料和颜料融入通用色树脂复合材料的 ΔE*ab 值分别为 3.3-4.6 和 2.2-9.6，而这些树脂复合材料的 ΔE00 值分别为 2.7-3.4 和 1.7-5.8。这些结果表明，所测试的散装填充树脂复合材料的颜色调节潜力受到修复深度的影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
