The aim of this study is to evaluate the effect of whitening toothpaste on the surface roughness of resin-based restorative materials by different measurement methods. Twenty four specimens from each of human enamel, a microhybrid composite and two nanohybrid composites discs (8.0 diameter × 4.0 mm thick) were divided into two groups (n = 12) according to toothbrushing solutıon and subjected to simulation toothbrushing (30,000 cycles) with both distilled water and whitening toothpaste containing blue covarine. Surface roughness was examined using atomic force microscopy (AFM), profilometer, and scanning electron microscopy (SEM), and the data obtained were subjected to analysis. Ra values of Tescera (TES) were significantly higher than Sonicfill 2 (SF2) when brushing both toothbrushing solutions for initial or 30,000 cycles. Roughness increased for SF2 and TES when brushed for 30,000 cycles and was higher than enamel and Herculite XRV Ultra (HXU). Human enamel was obtained lower surface roughness values brushed with toothpaste compared with distilled water. Evaluation of the surface roughness of control groups using the AFM revealed no statistically significant difference between the groups, but significant differences were found using a profilometer. The use of abrasive whitening toothpaste containing blue covarine and the number of brushing cycles affect the surface properties of human enamel and the restorative material, and also, the clinical success of the restoration. Toothbrushing for 30,000 cycles increased the surface roughness of all materials. The type of toothbrushing solution partially has affected surface roughness.

通过两种不同的方法：原子力显微镜和轮廓仪，研究各种修复材料刷牙后的表面粗糙度值。

本研究的目的是通过不同的测量方法评估美白牙膏对树脂基修复材料表面粗糙度的影响。来自人类牙釉质、微混合复合材料和两个纳米混合复合材料圆盘（直径 8.0 × 4.0 mm 厚）的 24 个样本被分为两组（n = 12) 根据刷牙解决方案，并使用蒸馏水和含有蓝色 covarine 的美白牙膏进行模拟刷牙（30,000 次循环）。使用原子力显微镜 (AFM)、轮廓仪和扫描电子显微镜 (SEM) 检查表面粗糙度，并对获得的数据进行分析。在初始或 30,000 次循环使用两种牙刷溶液时，Tescera (TES) 的 Ra 值显着高于 Sonicfill 2 (SF2)。SF2 和 TES 的粗糙度在刷 30,000 次循环后增加，并且高于搪瓷和 Herculite XRV Ultra (HXU)。与蒸馏水相比，用牙膏刷牙的人牙釉质表面粗糙度值较低。使用 AFM 评估对照组的表面粗糙度显示各组之间没有统计学上的显着差异，但使用轮廓仪发现了显着差异。使用含有蓝色covarine的研磨美白牙膏和刷牙次数会影响人牙釉质和修复材料的表面特性，也会影响修复的临床成功率。刷牙 30,000 次循环增加了所有材料的表面粗糙度。牙刷溶液的类型部分地影响了表面粗糙度。修复的临床成功。刷牙 30,000 次循环增加了所有材料的表面粗糙度。牙刷溶液的类型部分地影响了表面粗糙度。修复的临床成功。刷牙 30,000 次循环增加了所有材料的表面粗糙度。牙刷溶液的类型部分地影响了表面粗糙度。
