To assess the color stability and surface roughness of bioactive resin-based composite following exposure to coffee staining and brushing with whitening toothpastes.
Disk-shaped specimens of Filtek Z250 (FZ), Beautifil Flow Plus (BFP), Activa Presto (AP), and Fuji II LC (FII) were stained with coffee and then brushed with one of three toothpastes, conventional (C-TP), non-peroxide whitening (W-TP) or hydrogen peroxide-containing whitening toothpaste (HPW-TP) for 10 000 cycles. Changes in color (ΔE) and surface roughness were measured.
Two-way ANOVA revealed a significant interaction between restorative material and toothpaste type in roughness (p = 0.049) and ΔE (p = 0.007). FII consistently had the highest surface roughness change across all toothpastes, and AP showed significantly higher value than BFP and FZ with C-TP and W-TP (p < 0.001). For color change, FII displayed significantly higher ΔE between baseline and staining, as well as between staining and post-brushing with every toothpaste (p < 0.001). All materials had clinically unacceptable ΔE ranging from 4.82 ± 1.72 to 11.15 ± 1.44 post-brushing compared to baseline with every toothpaste, with the lowest value observed in Fll with W-TP (p < 0.001). For individual color parameters (ΔL, Δa, Δb), AP exhibited significantly greater ΔL changes between baseline and post-brushing compared to FZ, BFP, and FII (p < 0.001). No significant differences were observed for Δa or Δb across materials at any measurement stage (p > 0.05). Additionally, the effect of toothpaste type on individual parameters, as well as the interaction between material and toothpaste type, was nonsignificant (p > 0.05).
All materials tested showed increased roughness and unacceptable staining with none returning to baseline color or achieving acceptable color change post toothbrushing, irrespective of toothpaste type.
Understanding the effects of staining and whitening toothpastes on bioactive resin-based composites is important for optimizing material selection and maintenance protocols to ensure long-lasting esthetic outcomes in patients prone to staining.
评估生物活性树脂基复合材料在接触咖啡染色及用美白牙膏刷牙后的颜色稳定性和表面粗糙度。
将Filtek Z250（FZ）、Beautifil Flow Plus（BFP）、Activa Presto（AP）和Fuji II LC（FII）的圆盘形试件用咖啡染色，然后用三种牙膏之一，即传统牙膏（C-TP）、非过氧化物美白牙膏（W-TP）或含过氧化氢的美白牙膏（HPW-TP）刷牙10000次循环。测量颜色变化（ΔE）和表面粗糙度。
双向方差分析显示，修复材料和牙膏类型在粗糙度（p = 0.049）和ΔE（p = 0.007）方面存在显著交互作用。在所有牙膏中，FII始终具有最高的表面粗糙度变化，并且在使用C-TP和W-TP时，AP的表面粗糙度值显著高于BFP和FZ（p < 0.001）。对于颜色变化，FII在基线与染色之间以及染色与使用每种牙膏刷牙后之间均显示出显著更高的ΔE（p < 0.001）。与基线相比，使用每种牙膏刷牙后，所有材料的临床可接受ΔE范围为4.82±1.72至11.15±1.44，其中在使用W-TP的FII中观察到的值最低（p < 0.001）。对于各个颜色参数（ΔL、Δa、Δb），与FZ、BFP和FII相比，AP在基线与刷牙后之间显示出显著更大的ΔL变化（p < 0.001）。在任何测量阶段，各材料之间的Δa或Δb均未观察到显著差异（p > 0.05）。此外，牙膏类型对各个参数的影响以及材料与牙膏类型之间的交互作用均不显著（p > 0.05）。
所有测试材料均显示粗糙度增加且染色不可接受，无论牙膏类型如何，刷牙后均未恢复到基线颜色或实现可接受的颜色变化。
了解染色和美白牙膏对生物活性树脂基复合材料的影响对于优化材料选择和维护方案非常重要，以确保在易染色患者中获得持久的美学效果。
