The aim of this study was to determine the influence of mouthrinses on the surface roughness of a nanofilled composite resin after toothbrushing. One hundred nanofilled composite resin specimens were prepared and randomly distributed into two groups-brushed and non-brushed-and then assigned to five subgroups, according to the mouthrinse solutions (n = 10): Colgate Plax Fresh Mint, Oral B, Cepacol, Colgate Plax, and artificial saliva. Each sample was immersed in 20 mL of the mouthrinses for 1 minute, 5 days per week, twice a day, for a 3-week period. The control group used in the study was one in which the specimens were not subjected to brushing and remained only in artificial saliva. Toothbrushing was performed once a week for 1 minute, for 3 weeks. Surface roughness measurements (Ra) were performed after the immersion period and toothbrushing, by means of a profilometer. Data were analyzed by two-way ANOVA and Tukey's test. Analysis revealed that the association between toothbrushing and Colgate Plax Fresh Mint produced the lowest surface roughness (p < 0.05). All other groups tested (Oral B, Cepacol, Colgate Plax, artificial saliva) exhibited no statistically significant differences between surfaces, whether subjected to toothbrushing or not (p < 0.05). It was concluded that the surface roughness of the nanofilled composite resin tested can be influenced by the mouthrinse associated with toothbrushing.
本研究旨在确定漱口对牙刷牙后纳米复合树脂表面粗糙度的影响。制备了 100 个纳米复合树脂样本，并随机分为两组——刷牙组和非刷牙组，然后根据漱口液（n=10）分为五个亚组：高露洁派斯薄荷、欧乐 B、仙柏力克、高露洁派斯和人工唾液。每个样本均在 20ml 的漱口液中浸泡 1 分钟，每周 5 天，每天两次，持续 3 周。研究中使用的对照组是指样本未进行刷牙且仅置于人工唾液中的组。每周进行一次 1 分钟的刷牙，持续 3 周。浸泡期和刷牙后，使用轮廓仪进行表面粗糙度测量（Ra）。数据通过双因素方差分析和 Tukey 检验进行分析。分析显示，刷牙和高露洁派斯薄荷之间的关联产生了最低的表面粗糙度（p<0.05）。所有其他测试组（欧乐 B、仙柏力克、高露洁派斯、人工唾液）在是否进行刷牙方面，表面之间均无统计学差异（p<0.05）。结论是，所测试的纳米复合树脂的表面粗糙度可能受到与刷牙相关的漱口液的影响。
