Abstract

Purpose: 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.

Methods: 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).

Results: 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.

Clinical significance: Whitening toothpastes were not capable of maintaining the color stability of the three resin composites after 8 weeks of toothpastes-cigarette smoking cycling.

美白牙膏-香烟循环中树脂复合材料粗糙度和光学性能的演变。

目的:评价吸烟循环美白牙膏(WTCS)对微填充、微杂化和纳米填充树脂复合材料粗糙度、颜色、半透明度和光泽度演变的影响。方法:将Durafill - DVS、Empress Direct - ED和Z350 - FZ的15个样品根据牙膏分为常规组、对照组、高露洁- C组和美白组(高露洁夜光白- CW组和Oral B 3D白- OW组)，并在提交WTCS前、后进行8周的粗糙度、颜色、透明度和光泽度评价。数据分析采用双因素方差分析、三因素重复测量方差分析和Tukey HSD事后检验(α= 0.05)。结果:WTCS后，只有ED和FZ刷CW和FZ刷C后粗糙度增加。WTCS后，三种复合材料的颜色都发生了明显的变化。除CW刷刷的DVS外，其他各组在WTCS后透明度均显著降低。DVS是WTCS后唯一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的演变方面，美白牙膏的表现与传统牙膏相似。临床意义:美白牙膏不能维持牙膏-香烟循环8周后三种树脂复合材料的颜色稳定性。
