To evaluate the effect of cycling whitening toothpaste with cigarette smoking (WTCS) on the evolution of roughness, color, translucency, and gloss of microfilled, microhybrid, and nanofilled resin composites.
15 specimens of Durafill - DVS, Empress Direct - ED, and Z350 - FZ were divided into three groups according to the toothpastes:: conventional, control group, (Colgate - C) and Whitening (Colgate Luminous White - CW and Oral B 3D White - OW) and roughness, color, translucency, and gloss were evaluated before and after the specimens were submitted to WTCS for 8 weeks. Data were analyzed by two-way ANOVA, 3-way repeated measures ANOVA, and Tukey HSD post hoc test (α= 0.05).
Only ED and FZ brushed with CW and FZ brushed with C presented an increase in roughness after WTCS. The three composites suffered a significant color alteration after WTCS. Excepting DVS brushed with CW, all the other groups presented a significant reduction in translucency after WTCS. DVS was the only resin composite that maintained its gloss stability after WTCS. Whitening toothpastes behaved similarly to conventional (control) toothpaste regarding the evolution of roughness and optical stability of the three resin composites.
Whitening toothpastes were not capable of maintaining the color stability of the three resin composites after 8 weeks of toothpastes-cigarette smoking cycling.
评估含烟循环美白牙膏（WTCS）对微填料、微混合填料和纳米填料树脂复合材料的粗糙度、颜色、半透明度和光泽度变化的影响。
将15个Durafill - DVS、Empress Direct - ED和Z350 - FZ样本根据牙膏分为三组：传统对照组（高露洁 - C）和美白组（高露洁亮白 - CW和欧乐 - B 3D美白 - OW），在样本进行8周的WTCS处理前后评估其粗糙度、颜色、半透明度和光泽度。数据通过双向方差分析、三因素重复测量方差分析和Tukey HSD事后检验进行分析（α = 0.05）。
WTCS处理后，只有用CW刷牙的ED和用C刷牙的FZ粗糙度增加。三种复合材料在WTCS处理后颜色均发生显著变化。除了用CW刷牙的DVS外，所有其他组在WTCS处理后半透明度均显著降低。DVS是唯一一种在WTCS处理后保持光泽稳定性的树脂复合材料。在三种树脂复合材料的粗糙度和光学稳定性变化方面，美白牙膏的表现与传统（对照）牙膏相似。
经过8周的牙膏 - 吸烟循环处理后，美白牙膏无法保持三种树脂复合材料的颜色稳定性。
