This study aimed to investigate the colorimetric properties of newly developed composites for dental trauma splints using various staining solutions during the clinical splinting period. The clear shades of G-Fix (GF), Ortho Connect Flow (OC), Light Fix (LF), and Filtek Z350XT (FZ) were fabricated into 96 disk-shaped specimens. Specimens from each composite group were stored in distilled water, coffee, tea, and red wine solutions at 37ºC. CIE values were measured using a spectrophotometer at 24 h after specimen preparation and at 1 day, 1 week, 2 weeks, 3 weeks, and 4 weeks after storage in each solution. Color differences and translucency parameters were calculated using the initial and measured values. Within the experiment period, the color differences of GF, OC, and LF compared to the initial measurement were smaller than that for FZ for all staining solutions except distilled water. There were no significant color differences between the GF, OC, and LF groups.
本研究旨在探讨在临床夹板期使用各种染色溶液时，新开发的牙科创伤夹板复合材料的比色性能。将 G-Fix（GF）、Ortho Connect Flow（OC）、Light Fix（LF）和 Filtek Z350XT（FZ）的透明色制成 96 个圆盘状样本。将每个复合材料组的样本分别储存在 37°C 的蒸馏水中、咖啡、茶和红酒溶液中。在样本制备后 24 小时以及在每种溶液中储存 1 天、1 周、2 周、3 周和 4 周后，使用分光光度计测量 CIE 值。使用初始值和测量值计算色差和半透明度参数。在实验期间，与初始测量值相比，除蒸馏水外，GF、OC 和 LF 对所有染色溶液的颜色差异均小于 FZ。GF、OC 和 LF 组之间没有明显的颜色差异。
