The surface properties and color stability of interim crown materials may vary depending on the toothbrushing procedure. This study aimed to investigate the effects of toothbrushing and different toothpastes on the surface roughness (Ra) and color stability of different interim crown materials. Disc-shaped specimens were prepared from four interim crown materials (Tab 2000 (ChPM), Imident (LaPM), Protemp 4 (ChDM), and Telio-CAD (CadPM)). Specimens were divided into four subgroups for the control group (Cnt) and for simulated toothbrushing with distilled water (Dw) or with two different toothpastes (whitening toothpaste (WTp), activated charcoal toothpaste (ACTp)). The specimens’ Ra values were measured before and after 10,000 cycles of toothbrushing. The color parameters were measured and the color differences (ΔE00) were calculated. Data were statistically analyzed by two-way analysis of variance (ANOVA) and Tukey’s HSD tests. A significant increase in the Ra values was observed after toothbrushing, except for the LaPM_Dw, ChDM_Dw, and all the CadPM specimens (p < 0.05). Toothbrushing with toothpastes increased the ΔE00 values of all ChPM and ChDM interim materials (p < 0.05). Before and after all toothbrushing procedures, the CadPM specimens had smoother and ChPM specimens had rougher surfaces than the other interim materials. The two tested toothpastes had similar effects on the Ra of all interim materials. Non-perceivable color changes were seen only with the CadPM_Dw group.
临时冠材料的表面特性和颜色稳定性可能会因刷牙方式而异。本研究旨在探讨刷牙及不同牙膏对不同临时冠材料表面粗糙度（Ra）和颜色稳定性的影响。从四种临时冠材料（Tab 2000（化学固化甲基丙烯酸酯类）、Imident（光固化甲基丙烯酸酯类）、Protemp 4（化学固化双甲基丙烯酸酯类）和Telio-CAD（计算机辅助设计树脂类））制备圆盘形试件。试件分为四个亚组，分别为对照组（Cnt）以及用蒸馏水（Dw）或两种不同牙膏（美白牙膏（WTp）、活性炭牙膏（ACTp））模拟刷牙的组。在刷牙10000次循环前后测量试件的Ra值。测量颜色参数并计算颜色差异（ΔE00）。数据采用双向方差分析（ANOVA）和Tukey氏HSD检验进行统计学分析。除了LaPM_Dw、ChDM_Dw和所有CadPM试件外，刷牙后观察到Ra值显著增加（p<0.05）。用牙膏刷牙增加了所有ChPM和ChDM临时材料的ΔE00值（p<0.05）。在所有刷牙程序前后，CadPM试件的表面比其他临时材料更光滑，而ChPM试件的表面更粗糙。两种测试牙膏对所有临时材料的Ra有相似的影响。仅在CadPM_Dw组中观察到不可察觉的颜色变化。
